Michael Niedermayer	3bb465245f	h261dec: Fix context initialization sequence ff_mpv_common_init sets s->context_initialized. This fixes decoding of h261 in the cases where the demuxer hasn't already set the frame size. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	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

Reimar Döffinger	e8d0b84e8a	h261dec, ituh263dec: Move condition. Stops compiler from doing incredibly stupid things. With vsynth1-flv inner loop goes from 3501 to 3275 decicycles. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago

Reimar Döffinger	2a00812d82	h261dec, ituh263dec: Avoid unnecessary -1 inside inner loop. 3646 -> 3597 decicycles in inner loop when decoding vsynth1-flv. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago
Reimar Döffinger	c0d32686dd	h261dec: Optimize new RL_VLC based decoding. Together with the switch to RL_VLC this results in about 10% speedup for this inner loop. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago

John Stebbins	552bc42df4	h261dec: Fix order of initialization ff_MPV_common_init requires the frame dimensions which get parsed in h261_decode_picture_header.	11 years ago
John Stebbins	998c9f15d1	idct: remove call to ff_idctdsp_init from ff_MPV_common_init One step in untangling the mpegvideo code and fixing some problems in the order that initialization is being done in h263dec and h261dec.	11 years ago

wm4	f6774f905f	mpegvideo: operate with pointers to AVFrames instead of whole structs The most interesting parts are initialization in ff_MPV_common_init() and uninitialization in ff_MPV_common_end(). ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL checks for Picture.f, because these functions can be called on uninitialized or partially initialized Pictures. NULL pointer checks are added to ff_thread_release_buffer() stub function. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	11 years ago

Anton Khirnov	66499f34b5	mpegvideo: do not set current_picture_ptr in decoders This code was originally added in `5f1948111a` to h263 to set decoded frame pts to some random numbers (removed in `a1c5cc429d`) and then cargo culted to other decoders. The code is left in h263dec for now, since some part of the decoder (apparently OBMC) relies on the specific previous frame to be reused.	11 years ago

Michael Niedermayer	5e50a5724b	Revert "removing lowres support" There have been multiple user complaints about loosing this feature while its not clear the 3% speedloss claims where real or fabricated. My own testing indicates no statistically significant speed difference both with mpeg2 and mpeg4, and if at all the code with lowres support is a tiny bit faster than without. This reverts commit `92ef4be4ab`, reversing changes made to `2e07f42957`.

Reimar Döffinger	5735f768b0	h261: move tables from header to .c file. Currently they end up twice in the binary, since both encoder and decoder include the header and thus each gets their own copy. This is clearly nonsense for the const tables, but shouldn't be necessary for the RLTable either. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
