[Ffmpeg-devel] [PATCH] libavformat/utils.c/truncate_ts shouldn't truncate AV_NOPTS_VALUE

[Andy Parkins]

Hello,

I was getting strange behaviour where the PTS of an encoded stream was 
discontinuous and cyclic.  I was using an MPEGTS container for MPEG4 video 
(although I don't think that matters).  The problem, I think, is that 
mpegts_write_packet() (et al) tests for pts being equal to AV_NOPTS_VALUE; 
however truncate_ts() has already masked pts.

The fix was simply to stop truncate_ts from doing any truncation in the 
special case of the timestamp being AV_NOPTS_VALUE (for both pts and dts)

It's certainly fixed my problem, is there any reason I shouldn't do this?
