## WEB播放器 |

### WasmVideoPlayer |

||||
|
||||
在 Web 端进行软解码首先会想到使用 JavaScript。libde265.js 是用 C 开发的开源 H.265 编解码器 libde265 的 JavaScript 版本(确切地说是 libde265 的 asm.js 版本，后面会说明)。经测试，使用 libde265.js 并不是一个音视频播放的完善方案，存在帧率偏低和音视频不同步等问题。此外，JavaScript 作为解释型脚本语言，对于 H.265 解码这种重度 CPU 密集型的计算任务而言，也不是理想的选择，于是继续探寻更优方案。 |

## Android/iOS video player |
||||
|
||||
### ijkplayer |
||||
|
||||
h265 is disabled by default, you need to modify config/module-lite.sh to enable it, see README. |

mpegts 支持H265只能在PC、Android浏览器上播放 iOS不行 |

https://blog.csdn.net/smallhujiu/article/details/81703434 |
||||
|
||||
RTMP进行了标准扩展，播放器上ijkplayer也扩展了该修改。 |

### ZFPlayer |

|

基于AVPlayer，支持横屏、竖屏（全屏播放还可锁定屏幕方向），上下滑动调节音量、屏幕亮度，左右滑动调节播放进度。 |

支持hevc flv ffmpeg已完成编译 |
||||
|
||||
``` |
||||
/root/ffmpeg_sources/ffmpeg |
||||
``` |
||||
|
||||
修改文件： |
||||
|
||||
``` |
||||
libavformat/flv.h |
||||
libavformat/flvenc.c |
||||
libavformat/flvdec.c |

``` |
||||
|
||||
nginx-rtmp stat模块无法准确识别H265编码 |
||||
|
||||
|
||||
|
||||
测试推流命令行： |
||||
|
||||
``` |
||||
~/bin/ffmpeg -re -i rtsp://192.168.3.101/ch01 -c:v libx265 -profile:v main -c:a aac -b:a 128k -f flv rtmp://127.0.0.1:1935/live/test |
||||
``` |
||||
|
||||
|
||||
|
||||
## TS |
||||
|
||||
H265封装成TS流，查看openHEVC-ffmpeg-2.5源代码，及一些H265的TS流视频文件，基本的方式跟H264是一样的，这里主要注意的地方就是流类型不一样，H264的值为0x1b，H265的值为：0x24 |
||||
|
||||
**MPEG-2 TS** |
||||
https://blog.csdn.net/smallhujiu/article/details/80753765 |
||||
|
||||
转格式： |
||||
|
||||
``` |
||||
ffmpeg -i input.mp4 -c copy output.ts |
||||
ffmpeg -i input.mp4 -c copy output.flv |
||||
#从1.mp4 copy一个文件，使其moov头在尾部 |
||||
ffmpeg -i 1.mp4 -c copy -f mp4 output.mp4 |
||||
#从1.mp4 copy一个文件，使其moov头在头部： |
||||
ffmpeg -i 1.mp4 -c copy -f mp4 -movflags faststart output2.mp4 |
||||
#测试flv->ts |
||||
~/bin/ffmpeg -i rtmp://127.0.0.1:1935/live/testh265 -c copy -y -f mpegts 265.ts |
||||
|
||||
报错： |
||||
video:0kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown |
||||
``` |
||||
|
||||
|
||||
|
||||
GPAC可以把x265生成的hevc流(.hevc)打包成.mp4和.ts文件，其使用方法如下： |
||||
|
||||
**MP4Box** |
||||
|
||||
``` |
||||
./MP4Box -add name_of_annexB_bitstream.(bit,bin,265) -fps 50 -new output.mp4 |
||||
./MP4Box -v -add Catus_1920x1080_50_qp32.bin:FMT=HEVC -fps 50 -new output.mp4 |
||||
./MP4Client output.mp4 # to play HEVC mp4 content |
||||
``` |
||||
|
||||
|
||||
|
||||
**mp42ts** |
||||
|
||||
``` |
||||
./mp42ts -prog=hevc.mp4 -dst-file=test.ts |
||||
./mp42ts -prog=output.mp4 -dst-file=hevc.ts |
||||
./MP4Client test.ts # to play HEVC transport streams |
||||
``` |
