Android-在mp4容器中混合原始h264

Question

I have raw h264 data of my frames and its presentationTimeUs and I want to mux data in mp4 container. How can I do it with ffmpeg or any library except MediaMuxer ?

Update: I need a command to write h264 data of just one frame to mp4 container including presentatoinTimeUs

Answer 1

You can't write arbitrary H264 raw data without associated meta-information, either with ffmpeg or any library. Container such as MP4 exist so that a player knows how to handle that raw data (eg each frame's PTS, codec configuration, movie size, color format, etc), and more things that are not included in the raw compressed video stream.

You can however do the reverse, if you need to later analyze a compressor's bitstream:

ffmpeg -i file.mp4 -f h264 out.h264
