Description
Summary of the bug:
How to reproduce:
% ffmpeg -fflags +genpts -i test.avi -c copy test.mkv
Many video players (MPC-HC/BE, VLC) can not play H.264 video files remuxed by ffmpeg from avi to mkv or mp4 without lots of droppe frames (B-frames?).
Is this ffmpeg's problem? Or MPC-HC/BE, VLC?

Please provide the failing command line together with the complete, uncut console output to make this a valid ticket.

Command does not fail. But produced video file can not be played smoothly (without dropped frames) in VLC, MPC-HC, MPC-BE.

I compared mkv generated by ffmpeg with generated by mkvtoolnix (it plays fine with VLC,MPC-HC/BE). Looks like ffmpeg generates PST in different (wrong?) order. Maybe problem in genpts?
Look at frames 16-17-18-19-..:
