Hi Devel-List,

i have trouble to use ffmpeg to generate MPEG2-TS files. I?ve read in
this mailling list and on IRC, that the mpegts.c file is currently broken.

Maybe i can help by giving you a detailed error-log from a DEKTEC DTU-225SX
Hardware-Realtime analyser and the used Testfile.

If i could something else do for solving this problem, please inform me.
I?ve no
time to fix the problem by myself, but i can do further analysing for you.

My origin testfile:
hxxp://retro-park.de/download/trailer/Dracula_1930.mpg (a free trailer)

Mirror (pls. use this for download):
http://134.102.96.93/~alex/ffmpeg/Dracula_1930.mpg

The (broken) ffmpeg MPEG2-TS file:
http://134.102.96.93/~alex/ffmpeg/Dracula_1930.mpg

The error-log:
http://134.102.96.93/~alex/ffmpeg/error-log.txt

My ffmpeg-parameters:

ffmpeg -i Dracula_1930.mpg -r 25 -g 50 -s 720x576 -aspect 4:3 -b 384
-maxrate 6000 -ps 1024 -bufsize 128000 -qmax 3 -bf 2 -er 3 -benchmark -hex
-vstats -f mpegts -vcodec mpeg2video Dracula_1930_ts.mpg

Thanks and best regards
