[MPlayer-users] mplayer not finding TrueHD audio track in m2ts-stream

[Rune Svendsen]

Using -demuxer lavf causes a memory leak in mplayer, it hangs after
outputting the following:

        rune at runescomp:~$ mplayer -demuxer
        lavf /media/bigdisk/00007.m2ts

If I run mplayer with the -demuxer lavf option on the original (32GB)
file it just continues consuming more and more memory until I kill the
process.

Running it on a file cut down to the first 100MB of the original 32GB
file gives the following output:

I get no video playback from running this command, mplayer just closes
immediately.
        
I've tried uploading the 100 MB sample to the FTP here:
ftp://upload.mplayerhq.hu/MPlayer/incoming/ . The transfer _seems_ to
succeed but I'm not able to view the file in that directory so it looks
like the file hasn't been uploaded.
