[Live-devel] openRTSP-captured mp4 broken

[Marcin]

Hello,
I had to do almost the same goal as You - record incomming AV stream 
(h264/aac) to MP4 files. What i did was that live555 only dumped streams 
into separate files and then i used MP4Box to merge them into working 
mp4 file.
Greetings,
Marcin

However, this is difficult to do well, because the ".mp4" file format is ill-suited for what we are trying to do here: Record a file that properly represents incoming audio and video frames that are time-stamped.  But undoubtedly this is one part of our code that could be improved.
