[FFmpeg-devel] what to do when a patch breaks regression test

[Pavel Koshevoy]

Hi,

I am trying to solve an issue JW Player is having with TS fragments 
produced by httpsegmenter -- 
http://code.google.com/p/httpsegmenter/source/browse/trunk/segmenter.c

Essentially, JW Player can't handle fragments that do not start with a 
PAT/PMT packet.  Currently TS muxer outputs PAT/PMT periodically every 
40 packets.  What I did was to force it to output PAT/PMT on every video 
keyframe as well.  I think this change is justified because of this 
comment in mpegtsenc.c --  /* Arbitrary values, PAT/PMT could be written 
on key frames */.

Of course this breaks the TS muxer regression test:

TEST    lavf-swf
TEST    lavf-tga
TEST    lavf-tiff
TEST    lavf-ts

What should I do now?  Do I need to update the test?  If yes -- how?  
Will my patch be accepted into master?

Thank you,
     Pavel.
