[FFmpeg-devel] [PATCH] MPEG-TS/-PS : better probing for duration and start-time for all streams in a container

I have uploaded 2 mpg files (with corresponding *.txt) :
MPEGprobing_starttime-duration.mpg : the file I quoted in my previous post, 13Mo
MPEGprobing_starttime-duration2.mpg : the same file trimmed (symptoms remains strictly identical to the 13Mo version) = 6Mo to fit the 10Mo barrier limit if it were a very strong requirement for you (I was unsure about it)

It is not ideal because the starting of the file is a little bit "crude" : the two first B frames lack their P reference and an audio header missing is reported, but anyway it plays, and I can assure you that what is observed is exactly the same as real-life content strictly conformant to the standards. If needed, I could also with some more effort try to put this content on a production encoder to give you perfect sample files (but I cannot send you my everyday files because they are
