Framedrop errors in H.264

[ariel_gonz@…]

Click the "Download 1080 Version (129Mb)" link to download the MOV. When playing
with mplayer 1.0pre7 and the essential-20050412.tar.bz2 plugins, the video is
shown but with heavy artifacting and frame dropping. Machine speed should not be
a problem as I am able to play other 1080p movies.

During playback, the following errors will be shown on the console:
[h264 @ 009E3CB8]concealing 4896 DC, 4896 AC, 4896 MV errors
[h264 @ 009E3CB8]illegal short term buffer state detected
The "concealing" error will appear quite often, while the "illegal" message will
be displayed less frequently. These lines were not saved piped to the file while
doing "mplayer > textfile" and I will append a bigger sample at the bottom. Here
are my system specs and verbose output log.

Well, there is my first bugreport for mplayer. I have some experience with
Mozilla's Bugzilla, but please forgive me if I missed some information. Thanks!

[diego@…]

Does this happen with latest CVS as well? There were some fixes since pre7.

[ariel_gonz@…]

Apologies for not answering sooner...

Tested with the May 6, 2005 build from ​http://oss.netfarm.it/mplayer-win32.php
without any extra plugins. The visual artifacts are "different" but still there.
The error address (??) has changed in the error messages, but the content is the
same:

[h264 @ 008F9BC8]concealing 4896 DC, 4896 AC, 4896 MV errors
[h264 @ 008F9BC8]illegal short term buffer state detected

[diego@…]

There have been fixes since May 6. Try out _latest_ CVS.

[diego@…]

Loren, I'm assigning this to you as you are the local H.264 guru.

[lorenm@…]

Plays correctly with MPlayer dev-CVS-050512-09:00 on an Athlon-XP and an Opteron.
Also plays correctly with
​http://oss.netfarm.it/mplayer/builds/mplayer-k7-cvs-20050506.zip under Wine.
The relevant fix was applied on May 3.

[ariel_gonz@…]

Well, after playing around with the config file trying to figure out what could
be causing this, since its WFM for you guys, I discovered that the cause is that
I had framedropping active (framedrop=yes) in the config file.

Removing that line took care of the visual artifacts, as well as the error
messages. So this bug is WFM as well. I'm also changing the summary. Thanks!
