...on the flip side you can try to also report the issue to nero digital (link) who might be willing to fix it and send code patch to mplayer/ffmpeg

Quote:(pike) what's the gameplan for full h.264 support in ffmpeg/mplayer ?
(+dirtysheep) isnt h264 decoder in libavcodec almost complete?
(+dirtysheep) theres x264 too
(+dirtysheep) x264 is optional but not directly part of mplayer
(+dirtysheep) and for h264 status either wait
(+dirtysheep) or write to ffmpeg-users
Quote:it's not the same issue : vlc isn't a directshow player, so it can't use nero digital direct show filter to decode properly the video. it has instead to use ffmpeg, which is able to decode avc / h264, as far as b-frames & weighted prediction aren't enabled.
on the other hand, wmp, being a direct show player, can read .mp4 files filled with avc / h264 ( and so can mpc, zoom player, bsplayer & the like, which are far better than wmp, imho ), whatever the features enabled in the encoding.
concerning ffmpeg, the b-frames decoding seems to be on its way. weighted prediction may come later.

Quote:one is that ffmpeg doesnt support the full h264 specification. i've been told that if you disable certain settings in the advanced encoding profile in nero, they *might* playthanks for the idea ill do some quick tests to see if any of the options are responsible for making it unplayable

h.264 devel
2004-12-08 23:48
hello
i have a good experience on h.264 because i have work a lot on a decoder
recently, i"d like to help to improve the h.264 support in ffmpeg, i
could add multi slice support, fmo support, high profile support (8x8
transform, quantiser scale matrix...). i just want to know if anyone is
already working on some of this point so that the work is not done
twice.
best regards.

thanks, any contribution is appreciated.
i"m working on finishing b-frame support, but nothing overlapping your
proposal.
i can"t speak for anyone else, but i haven"t heard anything about high
profile being planned.
