/README.md:
--------------------------------------------------------------------------------
1 | * 目的: 一个基于FFmpeg视频转码 App 1.0 版本，名字叫【狗子】，英文名【Gouzi】。
2 | * 时间: 2018.11.8 ~ 2019.2.8 / 3 months / 12 weeks
3 | * 节奏: 每周一个小版本 version 0.1 0.2 0.3 ... 0.11 1.0，每周四发版本。
4 | * ver 0.4: 基本款：能用
5 | * ver 0.1 选视频
6 | * ver 0.2 整个集成 FFmpeg
7 | * ver 0.3 转码
8 | * ver 0.4 视频输出/Log展示
9 | * ver 0.8: FFmpeg 瘦身
10 | * ver 0.5 本地编译 FFmpeg 去掉不必要模块
11 | * ver 0.6 尝试直接调用 FFmpeg 库代码并适配 Android 端代码
12 | * ver 0.7 继续精简 FFmpeg 代码
13 | * ver 0.8 继续精简 Ffmpeg 代码
14 | * ver 1.0: 终极款：轻量
15 | * ver 0.9 - ver 1.0 继续精简 FFmpeg 代码
16 |
17 |
18 | 这个项目的难点不在于 Android 端，而在于 FFmpeg 的适配。由于 FFmpeg 没有 Android 版本，所以必须通过 JNI 方式配合 FFmpeg 编译的 so 包去配合使用。问题在于 FFmpeg 编译的 so 包体积非常大，全量编译包有将近 20M，这对于目前安装包只有 13M 的即刻来说是不可接受的。所以这个项目的大部分精力是用来精简 FFmpeg，计划从小版本 0.5 开始就做这部分。
19 |
20 | 精简的方式主要是自定义编译 FFmpeg 和代码层面对 FFmpeg 进行剪裁。第一部分相对简单，网上也有很多教程。难的是第二种方式，因为这里需要阅读 FFmpeg 源码，而 FFmpeg 几乎都是 c/c++ 写的，我上一次看 c 代码还是在大学时候。但第一种的精简大小很有限，必须尝试第二种。写这个开发计划的目的就是为了督促我知难而上，这部分代码也会放在我 github 的公开库上面，这么做的目的也是为了防止我半途而废，希望最后不要打脸🙏🙏🙏。

1 | ### H264 存储传输格式: Annex B / AVCC
2 |
3 | ```
4 | NALU is basic unit.
5 |
6 | Then,
7 |
8 | annexb format:
9 |
10 | ([start code] NALU) | ( [start code] NALU) |
11 |
12 | avcc format:
13 |
14 | ([extradata]) | ([length] NALU) | ([length] NALU) |
15 | ```
16 |
17 | In annexb, [start code] may be 0x000001 or 0x00000001.
18 |
19 | In avcc, the bytes of [length] depends on NALULengthSizeMinusOne in avcc extradata, the value of [length] depends on the size of following NALU and in both annexb and avcc format, the NALUs are no different.

21 | ### Annex B
22 |
23 | NALU/NAL: Network Abstraction Layer Units
24 | 开始码 00 00 00 01 / 00 00 01
25 | Nalu 第一个字节:
26 | bit0 通常为0
27 | bit1-bit2 为0表示没有被别的 nalu 引用，否则被别的 nalu 引用，值越大越重要
28 | bit3-bit7 表示 nalu type:
29 |
30 | | 0 | Unspecified | non-VCL |
31 | |---|---|---|
32 | |1|Coded slice of a non-IDR picture|VCL|
33 | |2|Coded slice data partition A|VCL|
34 | |3|Coded slice data partition B|VCL|
35 | |4|Coded slice data partition C|VCL|
36 | |5|Coded slice of an IDR picture|VCL|
37 | |6|Supplemental enhancement information (SEI)|non-VCL|
38 | |7|Sequence parameter set|non-VCL|
39 | |8|Picture parameter set|non-VCL|
40 | |9|Access unit delimiter|non-VCL|
41 | |10|End of sequence|non-VCL|
42 | |11|End of stream|non-VCL|
43 | |12|Filler data|non-VCL|
44 | |13|Sequence parameter set extension|non-VCL|
45 | |14|Prefix NAL unit|non-VCL|
46 | |15|Subset sequence parameter set|non-VCL|
47 | |16|Depth parameter set|non-VCL|
48 | |17..18|Reserved|non-VCL|
49 | |19|Coded slice of an auxiliary coded picture without partitioning|non-VCL|
50 | |20|Coded slice extension|non-VCL|
51 | |21|Coded slice extension for depth view components|non-VCL|
52 | |22..23|Reserved|non-VCL|
53 | |24..31|Unspecified|non-VCL|
