Description

I used ffmpeg2theora to reencode an mpeg2 video with theora. When i try to play the resulting file with mplayer, the video always freezes at the same position. However, the same file plays fine with vlc and the xine-based kaffeine.

The oggz-validate tool says the file is fine. I asked in the #theora irc channel and they said:

<bemasc> so, using oggz-dump <file> | grep serialno
<bemasc> I see that the point at which mplayer stops is the point at which there are zero-byte packets
<bemasc> and then immediately following is
<bemasc> serialno 1185899114, granulepos 1777|0, packetno 304: 101.547 kB
<brot> so that means that mplayer doesnt handle zero-byte packets right?
<bemasc> maybe
<bemasc> oggz-dump says
<bemasc> 00:01:10.880: serialno 1185899114, calc. gpos 1773|0, packetno 300: 304 bytes
<bemasc> 00:01:10.920: serialno 1185899114, granulepos 1773|1, packetno 301: 0 bytes
<bemasc> 00:01:10.960: serialno 1185899114, calc. gpos 1773|2, packetno 302: 0 bytes
<bemasc> 00:01:11.000: serialno 1185899114, granulepos 1773|3, packetno 303: 0 bytes
<bemasc> I believe the changing between "granulepos" and "calc. granpos" indicates that there's a whole page with only zero byte packets
<bemasc> which could be the special case mplayer can't handle

I used oggz-chop to extract the position. The file can be found here: http://share.minad.de/dl.php?f=8dl76d.ogv

Sorry for the delay, I can now confirm that the bug has been fixed. (Tested with mplayer 2:1.0~rc4.dfsg1-1 that just entered debian unstable amd64 recently.)
