wm4	13e4f2c7f7	mpeg4videodec: Remove useless messages They seem to sometimes trigger with old AVI files. They are just confusing, do not help anyone, and use sloppy language. Signed-off-by: Diego Biurrun <diego@biurrun.de>	10 years ago

Andreas Cadhalpun	1f47c2399d	mpeg4: only show the divx_packed warning, when a packed frame is present Otherwise it is shown even after the file was fixed with avidemux, because the userdata string still ends with 'p'.

Reimar Döffinger	46353759cb	mpeg4vdpau: Fix priv data size. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago
Anton Khirnov	7ea1b3472a	lavc: deprecate the use of AVCodecContext.time_base for decoding When decoding, this field holds the inverse of the framerate that can be written in the headers for some codecs. Using a field called 'time_base' for this is very misleading, as there are no timestamps associated with it. Furthermore, this field is used for a very different purpose during encoding. Add a new field, called 'framerate', to replace the use of time_base for decoding.	10 years ago

Diego Biurrun	a786c8259d	idct: Split off Xvid IDCT The Xvid IDCT is only required to decode some Xvid-encoded MPEG-4 files, so there is no point in having it as an unconditional part of idctdsp.	10 years ago
