[FFmpeg-user] FFMPEG has trouble processing file while VLC plays mp2ts just fine

Hello,

I have a major problem trying to read a video file using ffmpeg, while VLC
has no trouble replaying it. 

The video file can be processed by ffmpeg, but it loses pts, skips multiple
frames, and overall acts if video is broken.  This is especially evident
with silencedetect ... in VLC everything is pristine. Can someone please
help?


ffmpeg -i dd.m2ts -af silencedetect=noise=0.001 -f null -

It seems as if does not really fully know this format... The video is
generated by video recording program that records a broadcast. I tried
TVTest (https://github.com/tsukumijima/TVTest)  for Windows and also tried
recpt1 (https://github.com/stz2012/recpt1.git) and both of them produce the
same output. 

Can someone please help?
