FFMpeg将RGB图像编码为H264 [英] FFMpeg encoding RGB images to H264

问题描述

Hello
我开发了一个DirectShow过滤器，它有2个输入引脚（1个音频，1个视频）。我使用libavcodec / libavformat / libavutil的FFMpeg编码视频到H264，音频到AAC和mux it /流使用RTP。到目前为止，我能够使用libavcodec正确编码视频和音频，但现在我看到FFMpeg似乎也支持RTP多路复用。 Unfortunatelly，我找不到任何示例代码，显示如何执行H264编码和RTP多路复用。是否有人知道样品？

Hello I'm developing a DirectShow filter which has 2 input pins (1 for audio, 1 for video). I'm using libavcodec/libavformat/libavutil of FFMpeg for encoding the video to H264, audio to AAC and mux it/stream using RTP. So far I was able to encode video and audio correctly using libavcodec but now I see that FFMpeg seems to support RTP muxing too. Unfortunatelly, I can't find any example code which shows how to perform H264 encoding and RTP muxing. Does anybody know good samples?

推荐答案

尝试检查 HandBrake 。具体来说，此文件 muxmp4.c ，这是一个jem我发现使用FFMpeg / RTP。请务必正确使用 av_interleaved_write_frame（）和元数据字段。这些是我记得对于RTP的一些关键差异。

Try checking out the code in HandBrake. Specifically, this file muxmp4.c, which was a jem I found working with FFMpeg / RTP. Be sure and use av_interleaved_write_frame() and the extradata fields correctly. Those were some key differences I remember for RTP.

然而，我有一些稳定性问题与RTP / RTSP与FFMpeg，（我相信它变得更好）。我有更好的运气与 live555 ，你可以看看 VLC 和 MPlayer for好的例子如何使用它。

Still, I had some stability issues with RTP/RTSP with FFMpeg, (I'm sure it's getting better). I had much better luck with live555, and you can look at the code in VLC and MPlayer for good examples on how to use it.
