Description Arwed v. Merkatz 2004-02-25 17:01:24 UTC 
When playing mpeg4 video encoded with the 'packed bitstream' option by xvid
1.0(rc) xviddec shows every other frame completely in green.
If you need a sample file that shows this behaviour i can provide a small one.

Reporter, please add a link to a file so we can reproduce
Comment 2 Arwed v. Merkatz 2004-04-15 21:27:58 UTC 
sample file is available at
http://w3studi.informatik.uni-stuttgart.de/%7Evonmerad/xvidtest.avi

$ gst-launch-0.8 filesrc location=xvidtest.avi ! avidemux name=demux ! { queue !
xviddec ! xvimagesink } { demux. ! queue ! mad ! audioscale !
audio/x-raw-int,rate=48000 ! alsasink device=dsp1 }
=> shows green frames

$ gst-launch-0.8 filesrc location=xvidtest.avi ! avidemux name=demux ! { queue !
ffdec_mpeg4 ! xvimagesink } { demux. ! queue ! mad ! audioscale !
audio/x-raw-int,rate=48000 ! alsasink device=dsp1 }
=> plays it fine

xvid version: 1.0.0-rc2
gst-plugins version: 0.8.1
Comment 3 DJ 2004-07-20 21:53:40 UTC 
Vouching.  gst-plugins 0.8.1 + xvid 1.0.1.  Does the bug still exist in 0.8.2? 
mplayer 1.0_pre5 plays them fine so it doesn't seem to be a library problem.
Comment 4 Arwed v. Merkatz 2004-07-21 12:28:39 UTC 
Still happens with xvid 1.0.1, core 0.8.4 and plugins 0.8.2
Comment 5 Arwed v. Merkatz 2004-08-25 17:13:44 UTC 
Fixed by setting the XVID_LOWDELAY flag for decoding.
