[MPlayer-users] Fails to recognise long mpeg stream, works ok if truncated

[Jon Burgess]

Last night I recorded a part of a TV program using vdr. When I tried to 
play it back with mplayer it failed to recognise the stream. At first I 
thought it was probably my mistake so I tried a stream from a different 
recording and that worked fine. Then I discovered that if I truncate the 
file then mplayer detects and plays it fine, but something about the 
makeup of the stream makes it break if it is too long.

I have placed the first 4Mb of the program on the web at 
http://www.jburgess.uklinux.net/mpg-fail-4m

Playing this file with MPlayer-0.90,today's CVS and with the 
"demux_ts2.patch" and all failed. If however I truncate the file e.g.
# dd if=mpg-fail-4m of=file-2m bs=1k count=2k
Then the file-2m plays OK.

I also ran it through arpi's g2-preview9 and that seemed happy with the 
stream.

I have attached what I think are the interesting bits of the mplayer log 
below:
