While it can be used as a generic QUIC (and WebTransport) library, it also comes with experimental native RTP Over QUIC (RoQ) and Media Over QUIC (MoQ) support. At the time of writing, there's no support for HTTP/3 beyond the simple establishment of WebTransport connections. 5 | 6 | For more information and documentations, make sure you pay the [project website](https://imquic.conf.meetecho.com) a visit! 7 | 8 | > **Note well:** in its current stage, the library should be considered at an **alpha** stage, and very experimental due to its lack of support for some QUIC stack functionality. It is currently being used by Meetecho for prototyping RoQ and MoQ demos in local and controlled environments, and will probably not always work as expected in more challenging network scenarios. 9 | 10 | ## Dependencies 11 | 12 | To compile imquic, you'll need to satisfy the following dependencies: 13 | 14 | * [GLib](https://docs.gtk.org/glib/) 15 | * [pkg-config](http://www.freedesktop.org/wiki/Software/pkg-config/) 16 | * [quictls](https://quictls.github.io/) (QUIC TLS) 17 | * [Jansson](https://github.com/akheron/jansson) (optional; QLOG support) 18 | 19 | > **Note:** You can also use BoringSSL, instead of quictls, by passing `--enable-boringssl=`, albeit without early-data support. If BoringSSL is installed in `/opt/boringssl`, the configure script will expect header files in `/opt/boringssl/include` and shared (not static) objects in `/opt/boringssl/lib64`. You'll then need to manually export `LD_LIBRARY_PATH` to the path where BoringSSL shared objects are, when using an application that's linked to the library. 20 | 21 | Should you be interested in building the imquic documentation as well (public and internal), you'll need some additional tools too: 22 | 23 | * [Doxygen](https://www.doxygen.org) 24 | * [Graphviz](https://www.graphviz.org/) 25 | 26 | Notice that, at the time of writing, only Linux is supported as a target, but the library should compile on macOS as well. Both macOS and Windows, as well as other platforms, are planned as a target in future releases. 27 | 28 | ## Compile 29 | 30 | Once you have installed all the dependencies, just use: 31 | 32 | sh autogen.sh 33 | 34 | to generate the configure file. After that, configure and compile as usual to start the whole compilation process: 35 | 36 | ./configure --prefix=/usr 37 | make 38 | make install 39 | 40 | Note that the configure script uses `pkg-config` to look for quictls by using the `openssl+quictls` name, which is how it's packaged in some repositories to avoid conflicts with OpenSSL. In case that doesn't work for you, you can use the `QUICTLS_CFLAGS` and `QUICTLS_LIBS` environment variables to specify the include and lib directory of the library when launching the configure script, e.g. 41 | 42 | QUICTLS_CFLAGS="-I/opt/quictls/include/" \ 43 | QUICTLS_LIBS="-L/opt/quictls/lib64/ -lssl -lcrypto" \ 44 | ./configure [..] 45 | 46 | Should that still result in compilation issues, you can try adding the path to the quictls library to ld, which is what the above mentioned repositories do, e.g. 47 | 48 | echo "/opt/quictls/lib64" > /etc/ld.so.conf.d/quictls-x86_64.conf 49 | ldconfig 50 | 51 | If you're interested in QLOG support, add `--enable-qlog` when launching the `configure` script. Notice that this will require [Jansson](https://github.com/akheron/jansson). 52 | 53 | You can build some demo applications by adding `--enable-echo-examples` (basic QUIC/WebTransport client/server demos), `--enable-roq-examples` (RoQ demos) and `--enable-moq-examples` (MoQ demos). 54 | 55 | To build the documentation, add `--enable-docs`. 56 | 57 | ## Examples 58 | 59 | To learn more about the demo examples, refer to the related [README.md](examples/README.md). 60 | 61 | ## Help us! 62 | Any thought, feedback or (hopefully not!) insult is welcome! 63 | 64 | Developed by [@meetecho](https://github.com/meetecho) 65 | -------------------------------------------------------------------------------- /autogen.sh: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | 3 | srcdir=`dirname $0` 4 | test -z "$srcdir" && srcdir=. 5 | 6 | mkdir -p m4 7 | 8 | autoreconf --verbose --force --install || exit 1 9 | -------------------------------------------------------------------------------- /configure.ac: -------------------------------------------------------------------------------- 1 | AC_INIT([imquic],[0.0.1],[https://github.com/meetecho/imquic],[imquic],[https://imquic.conf.meetecho.com]) 2 | AC_LANG(C) 3 | AC_CONFIG_AUX_DIR([.]) 4 | AC_CONFIG_MACRO_DIR([m4]) 5 | 6 | AC_ENABLE_SHARED(yes) 7 | AC_ENABLE_STATIC(no) 8 | 9 | AM_INIT_AUTOMAKE([foreign subdir-objects]) 10 | AM_SILENT_RULES([yes]) 11 | 12 | AC_USE_SYSTEM_EXTENSIONS 13 | 14 | AC_PROG_CC 15 | 16 | LT_PREREQ([2.2]) 17 | LT_INIT 18 | 19 | # Common CFLAGS 20 | CFLAGS="$CFLAGS \ 21 | -fPIC \ 22 | -fstack-protector-all \ 23 | -fstrict-aliasing \ 24 | -pthread \ 25 | -Wall \ 26 | -Warray-bounds \ 27 | -Wextra \ 28 | -Wformat-nonliteral \ 29 | -Wformat-security \ 30 | -Wformat=2 \ 31 | -Winit-self \ 32 | -Wlarger-than=2097152 \ 33 | -Wmissing-declarations \ 34 | -Wmissing-format-attribute \ 35 | -Wmissing-include-dirs \ 36 | -Wmissing-noreturn \ 37 | -Wmissing-prototypes \ 38 | -Wnested-externs \ 39 | -Wold-style-definition \ 40 | -Wpacked \ 41 | -Wpointer-arith \ 42 | -Wsign-compare \ 43 | -Wstrict-prototypes \ 44 | -Wswitch-default \ 45 | -Wunused \ 46 | -Wno-unused-parameter \ 47 | -Wno-unused-result \ 48 | -Wwrite-strings \ 49 | -Werror=implicit-function-declaration" 50 | 51 | case "$CC" in 52 | *clang*) 53 | # Specific clang flags 54 | CFLAGS="$CFLAGS \ 55 | -Wno-initializer-overrides \ 56 | -Wno-missing-noreturn" 57 | ;;

Different blog posts 20 | * are available that provide more context, like this 21 | * QUIC intro, 22 | * a RoQ devblog 23 | * and one on MoQ. 24 | * The imquic repo also comes with a few \ref examples that 25 | * demonstrate the usage of all those protocols in different roles and 26 | * scenarios. 27 | * 28 | * While you can write your own RoQ and MoQ parsers on top of the raw 29 | * imquic QUIC functionality, the library also provides an internal 30 | * implementation of both protocols, with ad-hoc interfaces aimed at 31 | * making their use in an application as simple as possible. 32 | * 33 | * \par Public (API) and internal documentation 34 | * The documentation is divided in two parts: 35 | * 36 | * - a public documentation, in case you're interested 37 | * in using imquic in your application; 38 | * - an internal documentation, in case you're interested 39 | * in studying imquic and/oc contributing changes and fixes. 40 | * 41 | * \section copyright Copyright and author 42 | * 43 | * imquic © 2024-2025 Meetecho (https://www.meetecho.com/) 44 | * 45 | * \author Lorenzo Miniero ( \ref credits ) 46 | * 47 | * \section lcns License 48 | * This program is free software, distributed under the terms of the MIT 49 | * License.

Unfortunately, 77 | * this is not the world we live in, and so you might still encounter 78 | * issues using imquic, e.g., unexpected crashes and the like. We always 79 | * try and tackle bugs as soon as we spot them, but some issues may be 80 | * always lingering in the background. 81 | * 82 | * Should you encounter a bug or a crash, open a new 83 | * issue 84 | * on GitHub. Make sure you carefully read the 85 | * guidelines 86 | * for contributing, or otherwise we may decide to close the issue and 87 | * not even look at it. 88 | * 89 | * What's important for us to look into issues and bugs definitely is 90 | * having enough information to do so. As such, whenever possible try to 91 | * provide as many details and data as possible. Quite useful to us are 92 | * GDB stacktraces and/or AddressSanitizer output. The following sections 93 | * give a quick overview on how you can collect this information after 94 | * a crash, but for a more detailed description of the tools you should 95 | * refer to the related documentation pages and tutorials. 96 | * 97 | * \section gdb GDB 98 | * GDB is the GNU Project Debugger 99 | * and is an effective tool for looking at what has happened (or is 100 | * happening) inside an application. As such, it's quite useful to spot 101 | * bugs and the like, as it can provide information about the values of 102 | * variables when they were used and the application crashed. 103 | * 104 | * First of all make sure that debugging symbols are enabled by reconfiguring imquic like this: 105 | * 106 | \verbatim 107 | CFLAGS="-Og -g3 -ggdb3 -fno-omit-frame-pointer" ./configure [..] 108 | \endverbatim 109 | * 110 | * Once done configuring, do a \c make \c clean (to make sure 111 | * everything is recompiled from scratch) and then a \c make and \c make \c install. 112 | * 113 | * When imquic crashes, you should get a core dump file somewhere. This is 114 | * a recorded state of the application memory at the time of crashing, and 115 | * so a backtrace of what lead to an issue can help. You can open such 116 | * a core dump file via gdb this way: 117 | * 118 | \verbatim 119 | gdb /path/to/bin/your-imquic-app /path/to/coredump 120 | gdb bt 121 | \endverbatim 122 | * 123 | * The \c bt command retrieves the backtrace, and is what you should provide 124 | * as part of your new issue. 125 | * 126 | * \note Please \c DON'T paste this backtrace in the issue text. Use a 127 | * service like Gist or 128 | * Pastebin and pass the generated 129 | * link instead. 130 | * 131 | * \section sanitizer Address Sanitizer 132 | * An even better tool for spotting issues is 133 | * Address Sanitizer, 134 | * a fast memory error detector. Since it can spot memory errors, it's 135 | * very useful to find out about hidden race conditions and the like. 136 | * 137 | * Unlike GDB which can be used as is, though, to use Address Sanitizer 138 | * you'll first need to recompile imquic with some new settings, as it 139 | * requires a specific dependency on a library, libasan, which you'll need 140 | * to install through your repository manager if needed. Besides, you'll 141 | * need at least gcc 4.8 for this to work: older versions of gcc won't 142 | * work. 143 | * 144 | * Once you've installed libasan, reconfigure imquic like this: 145 | * 146 | \verbatim 147 | CFLAGS="-O0 -g3 -ggdb3 -fno-omit-frame-pointer -fno-optimize-sibling-calls -fsanitize=address -fsanitize-address-use-after-scope -fno-sanitize-recover=all" LDFLAGS="-fsanitize=address" ./configure [..] 148 | \endverbatim 149 | * 150 | * Of course you're free to add whatever additional configuration parameter 151 | * you were using before: the important parts are the environment variables 152 | * before that. Once done configuring, do a \c make \c clean (to make sure 153 | * everything is recompiled from scratch) and then a \c make and \c make \c install 154 | * as usual. 155 | * 156 | * At this point, your imquic version should be Address Sanitizer compliant. 157 | * To make sure, try using \c ldd to check whether libasan is indeed a 158 | * dependency or not: 159 | * 160 | \verbatim 161 | ldd src/.libs/libimquic.so | grep asan 162 | \endverbatim 163 | * 164 | * If it is, you're done: whenever imquic crashes for any reason, you'll 165 | * get additional output from Address Sanitizer automatically with details 166 | * on what went wrong, and that's what you should provide as part of the 167 | * issue content. Just as a side note, please beware that using Address 168 | * Sanitizer imquic will run just a bit slower, even though not to the 169 | * point of being unusable (as when using, e.g., valgrind). 170 | * 171 | * \note Please \c DON'T paste Address Sanitizer output in the issue text. 172 | * Use a service like Gist or 173 | * Pastebin and pass the generated 174 | * link instead. 175 | * 176 | */ 177 | 178 | /*! \page credits Credits 179 | * 180 | * imquic © 2024-2025 Meetecho (https://www.meetecho.com/) 181 | * 182 | * \b Author: 183 | * Lorenzo Miniero 184 | * 185 | * Several open source components have been used to implement this software: 186 | * 187 | * - \b GLib: http://library.gnome.org/devel/glib/ 188 | * - \b pkg-config: http://www.freedesktop.org/wiki/Software/pkg-config/ 189 | * - \b quictls: https://quictls.github.io/ (QUIC TLS) 190 | * 191 | */ 192 | 193 | /*! \page license License 194 | * 195 | * This program is free software, distributed under the terms of the MIT License. 196 | * 197 | * \verbinclude LICENSE 198 | */ 199 | 200 | /*! \page changelog Tagged versions and Changelog 201 | * 202 | * There are different tagged versions on the imquic repository.

Notice that they're meant as simple demo examples, and are not strictly speaking representative of the coding style you should adhere to, or indicative of the expected performance of the library. 5 | 6 | There are a few different client/server examples showing how you can use imquic for: 7 | 8 | * generic QUIC applications (raw QUIC and/or WebTransport); 9 | * native RTP over QUIC (RoQ) support; 10 | * native Media over QUIC (MoQ) support. 11 | 12 | You can choose which examples to build by passing arguments to the `./configure` script. 13 | 14 | All demos allow you to create QLOG files, assuming QLOG support is available in the library. You can enable it passing `-Q `, where `` will need to be the path to a valid folder for server examples, and a path to a file to create for client examples. By default, this will serialize QLOG to contained JSON files, but you can create sequential JSON files by passing `-J` instead. Notice that, even when QLOG is enabled, the examples won't save anything by default: you're required to specify what you want to trace using one or multiple calls to `-l ` (where `` can be `quic`, `http3`, `roq` or `moq`; `-l quic -l moq` will trace both QUIC and MoQ in the MoQ examples, for instance). 15 | 16 | ## Echo examples 17 | 18 | To build the client/server echo examples, pass `--enable-echo-examples` to the `./configure` script. This will build two command line applications, namely: 19 | 20 | * `imquic-echo-server`, a basic QUIC/WebTransport echo server; 21 | * `imquic-echo-client`, a basic QUIC/WebTransport echo client. 22 | 23 | Both provide a few configuration options: pass `-h` or `--help` for more information. 24 | 25 | This example launches a raw QUIC server (since `-q` is passed), negotiating the `doq` ALPN, listening on port `9000`, using the provided certificate, and saving the shared TLS secrets to the provided `SSLKEYLOGFILE` (e.g., for live debugging of the QUIC traffic via Wireshark): 26 | 27 | ./examples/imquic-echo-server -q -a doq -p 9000 -c ../localhost.crt -k ../localhost.key -s ../key_log.log 28 | 29 | This has the echo client connect to that server: 30 | 31 | ./examples/imquic-echo-client -q -a doq -r 127.0.0.1 -R 9000 32 | 33 | This other example launches a WebTransport server (since `-w` is passed) instead: 34 | 35 | ./examples/imquic-echo-server -w -p 9000 -c ../localhost.crt -k ../localhost.key -s ../key_log.log 36 | 37 | This has the echo client connect to that server: 38 | 39 | ./examples/imquic-echo-client -w -r 127.0.0.1 -R 9000 40 | 41 | In both cases, the client will then send a single `ciao` buffer on a bidirectional `STREAM` that the server will echo back. Both client and server can be configured to offer both raw QUIC and WebTransport at the same time. 42 | 43 | ## RTP Over QUIC (RoQ) examples 44 | 45 | To build the RTP Over QUIC (RoQ) examples, pass `--enable-roq-examples` to the `./configure` script. This will build two command line applications, namely: 46 | 47 | * `imquic-roq-server`, a basic RoQ server, that will just print the flow ID and RTP headers of the incoming packets; 48 | * `imquic-roq-client`, a basic RoQ client, that will listen for RTP packets on some UDP ports, and restream them via QUIC. 49 | 50 | Both provide a few configuration options: pass `-h` or `--help` for more information. 51 | 52 | This launches the RoQ server on port `9000`, using the provided certificate, and saving the shared TLS secrets to the provided `SSLKEYLOGFILE` (e.g., for live debugging of the QUIC traffic via Wireshark); raw QUIC is used (`-q`), but unlike before the ALPN is omitted, since it will automatically be set by the RoQ stack in the library: 53 | 54 | ./examples/imquic-roq-server -q -p 9000 -c ../localhost.crt -k ../localhost.key -s ../key_log.log 55 | 56 | This launches the RoQ client to connect to that server, waiting for audio RTP packets on port `15002` (whose flow ID on RoQ will be `0`) and for video RTP packets on port `15004` (whose flow ID on RoQ will be `1`), and using a separate `STREAM` for each RTP packet: 57 | 58 | ./examples/imquic-roq-client -q -a 15002 -A 0 -v 15004 -V 1 -r 127.0.0.1 -R 9000 -m streams 59 | 60 | Sending RTP traffic to those ports (e.g., from GStreamer, FFmpeg, Janus RTP forwarders or others), will have the RoQ client send them to the RoQ server. 61 | 62 | ## Media Over QUIC (MoQ) examples 63 | 64 | To build the Media Over QUIC (MoQ) examples, pass `--enable-moq-examples` to the `./configure` script. This will build a few command line applications, namely: 65 | 66 | * `imquic-moq-pob`, a basic MoQ publisher (basically a clone on `moq-clock` in [moq-rs](https://github.com/kixelated/moq-rs)); 67 | * `imquic-moq-sub`, a basic MoQ subscriber (with support for a few different kinds of media); 68 | * `imquic-moq-test`, a basic MoQ publisher/subscriber that implements the [testing protocol](https://afrind.github.io/moq-test/draft-afrind-moq-test.html) draft (still WIP); 69 | * `imquic-moq-relay`, a basic MoQ relay. 70 | 71 | All provide a few configuration options: pass `-h` or `--help` for more information. 72 | 73 | Having a relay available is a prerequisite for testing the client demos. The `imquic-moq-relay` application is a basic (and not very performant) relay implementation with support for most of the MoQ features. This launches a MoQ relay that can be reached both via raw QUIC and WebTransport (`-q -w`), and that only accepts connections negotiating version -07 of the draft (`-M`): 74 | 75 | ./examples/imquic-moq-relay -p 9000 -c ../localhost.crt -k ../localhost.key -q -w -M 7 -s ../key_log.log 76 | 77 | Assuming a relay (`imquic-moq-relay` or others) is listening on that address, this creates a MoQ publisher using WebTransport (`-w`) that publishes the current time to the `clock` namespace and `now` track; since `-M` is not provided, support for multiple versions of MoQ is offered: 78 | 79 | ./examples/imquic-moq-pub -r 127.0.0.1 -R 9000 -w -n clock -N now -w -s ../key_log.log 80 | 81 | A MoQ subscriber for that namespace/track (with `-t text` to tell the application to interpret the objects as text) using raw QUIC (`-q`) can be run as following: 82 | 83 | ./examples/imquic-moq-sub -r 127.0.0.1 -R 9000 -q -n clock -N now -t text -s ../key_log.log 84 | 85 | Assuming [moq-rs](https://github.com/kixelated/moq-rs)'s `moq-pub` application is publishing a video file to a relay, this command will subscribe to the MP4 container video (`-t mp4` will instruct the subscriber to save the objects to the provided file): 86 | 87 | ./examples/imquic-moq-sub -r 127.0.0.1 -R 9000 -w -n pippo -N 0.mp4 -t mp4 -o test.mp4 88 | 89 | Assuming Meta's [moxygen](https://github.com/facebookexperimental/moxygen) relay is running on that address and that a [moq-encoder-player](https://github.com/facebookexperimental/moq-encoder-player/) instance is publishing audio and video, this creates a MoQ subscriber (on WebTransport) to both tracks that prints the LOC header (`-t loc`) of each incoming object: 90 | 91 | ./examples/imquic-moq-sub -r 127.0.0.1 -R 4433 -w -H /moq -n vc -N 12345678-audio -N 12345678-video -a secret -t loc -w -s ../key_log.log 92 | 93 | `imquic-moq-sub` also supports `FETCH` to obtain objects from a relay, both in standalone and (assuming v08 of the draft is used) joining mode. You enable `FETCH` by specifying the order you want using `-f`: by default this enables standalone fetch, but if you want a joining one (meaning a `SUBSCRIBE` is sent too) you also need to specify the preceding group offset via the `-j` property. This is an example of subscribing to the current time with a joining fetch that's just interested in all objects from the latest group (`-j 0`): 94 | 95 | ./examples/imquic-moq-sub -r 127.0.0.1 -R 9000 -w -n clock -N now -t text -M 8 -f ascending -j 0 96 | 97 | `imquic-moq-test` implements the publisher side of the [MoQT tester draft](https://afrind.github.io/moq-test/). At the time of writing, even though it's a publisher, it acts as a QUIC and/or WebTransport server and never announces any namespace, meaning it's expected that subscribers interested in testing it will need to connect to it directly, as part of point-to-point functional tests. This is an example of how it can be launched as a server that supports both raw QUIC and WebTransport (since both `-q` and `-w` are passed): 98 | 99 | ./examples/imquic-moq-test -c ../localhost.crt -k ../localhost.key -p 9000 -q -w 100 | 101 | You can then use the demo subscriber to specify which objects should be delivered and how by using the namespace tuple as specified in the draft, e.g.: 102 | 103 | ./examples/imquic-moq-sub -r 127.0.0.1 -R 9000 -w -n moq-test-00 -n 0 -n 2 -n 1 -n 10 -n "" -n 6 -n 10 -n 2 -n 500 -n 2 -n 2 -n 1 -n 3 -n 3 -N "" 104 | -------------------------------------------------------------------------------- /examples/echo-client-options.c: -------------------------------------------------------------------------------- 1 | /* 2 | * imquic 3 | * 4 | * Author: Lorenzo Miniero 5 | * License: MIT 6 | * 7 | * Command line options for imquic-echo-client 8 | * 9 | */ 10 | 11 | #include "echo-client-options.h" 12 | 13 | static GOptionContext *opts = NULL;
