<span style='font-size:7pt;line-height:100%'>this is not a feature request</span>

i've searched here for information about 3ivx playback. seems results are spotty depending on container, so i thought getting this movie to play smoothly (it plays in xbmc [06-06] but choppy - lots of chunkiness, droppeds, earlies, lates) in xbmc was hopeless.

but then i tried it in xbmp and it plays smoothly except for a very bright, saturated strip of discoloration on the top of the video. i've played the movie on the pc in media player classic though ffdshow ("other mpeg4", libavcodec) and the edges as well as the picture quality are sharp and solid so i'm fairly certain the playback performance in xbmc and the discoloration in xbmp are not the result of a bad encoding job.

gspot proved it's uselessness by simply calling it standard quicktime. i've opened the file in a hex editor and all i can be sure of is that the audio is mp4a. i suspect the video is 3iv2 since in xbmc, without modifying codecs.conf, it's playing through the ffodivx "ffmpeg mpeg-4" videocodec set.

am i sunk? is it hopeless? is there no way to get it to play with the clarity of xbmc with the performance seen in xbmp? or do i just have to wait for some kind soul to get something going on the xbox 3ivx codec end? =p

this is not a feature requestwhy is this not a feature request (http://www.xboxmediaplayer.de/cgi-bin/forums/ikonboard.pl?act=st;f=4;t=2696)?, 3ivx is officialy not supported by xbmc, see http://www.xboxmediacenter.de/info_project.htm

what is the fourcc of the audio and video coded of the media file. does the same file play on a pc in mplayer for windows/linux?

<s>those answers are all in the post.</s> ah, missed the all-important "in mplayer" bit. hold on (dont love it, dont have it - gotta grab).

plays fine.

according to mplayer:
mp4a
mp4v '3ivx d4 4.5'

@vesh, you still haven't answered my fourcc codec question, xbmc does not show that. you need to use some third-party application (http://www.fourcc.org/codecs.php).

ps! as you can see on mplayer's website, mplayer does not nativly support any 3ivx codecs, fourcc "3iv1" is supported on mplayer for linux/windows through win32 dll's, dll's which xbmc does not support, (xbmc almost only support native mplayer codecs (http://www.xboxmediaplayer.de/cgi-bin/forums/ikonboard.pl?act=st;f=4;t=1921)):

according to mplayer:
mp4a
mp4v '3ivx d4 4.5'xbmc will try to play "mp4v" with ffmpeg mpeg-4 (mplayer native codec), not fully compatible so will cause the symtoms you see.
mplayer on pc on the other hand will likely play same with with "win32/quicktime mpeg-4 decoder" (quicktime.qts = win32 dll).

i'm merging your post into the existing feature suggestion thread for real 3ivx codec support as this is not yet supported by xbmc.
