I think there is some kind of regression with libavformat OR the way DVBCUT
uses it in the recent versions of ffmpeg SVN. This is in regards to exporting
MPEG2-TS to MPEG2-PS after editing with DVBCUT and exporting using the "MPEG
program stream/DVD (libavformat)" output. I'm currently using DVBCUT SVN 123.
The steps to reproduce the problem are as follows:
1) Compile and install a fresh checkout of ffmpeg
2) Open a MPEG2-TS file in DVBCUT
3) Make edits
4) Export as "MPEG program stream/DVD (libavformat)"
5) Process resulting MPEG2-PS using dvdauthor to a DVD
6) Play DVD in consumer grade 480i DVD player connected to television.
DVD will have lots of skipping, freezing, and audio problems, completely
unwatchable.
Now, redo the steps above except use "MPEG program stream/DVD (DVBCUT
multiplexer)" in step 4. Resulting DVD will play without any problem in the
DVD player.
Now, redo the above again, except compile and install SVN version 13060 of
ffmpeg first, and use "MPEG program stream/DVD (libavformat)" as the export
type. The resulting DVD will have no problems in the DVD player.
Summary: I was using ffmpeg 13060 for a long time with DVBCUT 123 and had no
problems exporting as "MPEG program stream/DVD (libavformat)". The next
version of ffmpeg that I installed was 14873 and I can confirm at least
somewhere inbetween those 2 versions something changed which prevents me from
exporting without problems as "MPEG program stream/DVD (libavformat)".
I'm not sure if this is an ffmpeg problem or not, but I figured the DVBCUT devs
would be best to start with. Thanks.
