How to dump the H264/RTP stream to a file without losing time info ?
3 février 2014, par Fernando SilveiraI coded an application to receive RTP packets via TCP (no packets are lost) from a hardware camera and dump its H264 packets to a file so I could play the video using MPlayer or VLC. This is already working and I pretty much did the steps described here. The commands to play the video are
mplayer -fps 24 -demuxer h264es foobar.h264
andvlc foobar.h264
.The issue is now when I play the video. The camera changes the FPS frequently and because I drop the RTP info when writing the H264 file, the timestamp of each frame is lost. My question is : what do I have to do to fix the frame frequency ? Should I create empty/blank P-frames (if that is possible) ? If so, how would I do it ?
Any solution using Linux compatible tools or libraries (like ffmpeg, libx264, libavcodec) using shell, C/C++ or Python is very much welcome.
PS : I have almost no experience with video encoding and RTP.
