Andreas Cadhalpun	072756cdd2	vc1dec: use get_bits_long and limit the read bits to 32 get_bits should not be used with more than 25 bits. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago

Luca Barbato	68211c70af	vc1: Do not assume seek happens after decoding If a seek is requested before the decoding start there is no current picture. CC: libav-stable@libav.org	10 years ago
Michael Niedermayer	a97328afef	vc1: Use logical instead of bitwise or for twomv CC: libav-stable@libav.org Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Tim Walker <tdskywalker@gmail.com>	10 years ago
Tim Walker	b5fe13448b	vc1: Use logical instead of bitwise or for coded_inter This appears to be the intended behavior.	10 years ago

Diego Biurrun	835f798c7d	mpegvideo: cosmetics: Lowercase ugly uppercase MPV_ function name prefixes	10 years ago
Ben Avison	adf8227cf4	vc-1: Add platform-specific start code search routine to VC1DSPContext. Initialise VC1DSPContext for parser as well as for decoder. Note, the VC-1 code doesn't actually use the function pointer yet. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Diego Biurrun	e3fcb14347	dsputil: Split off IDCT bits into their own context	11 years ago

Diego Biurrun	368f50359e	dsputil: Split off quarterpel bits into their own context	11 years ago
Anton Khirnov	5c1d7246cd	lavc: set AVCodecContext.hwaccel in ff_get_format() This way each decoder does not have to do the same thing manually.	11 years ago
Anton Khirnov	632ad2248e	lavc: Add an internal wrapper around get_format() It will be useful in the following commits.	11 years ago
Alessandro Ghedini	cdf6eb5a97	vc1: Do not return an error when skipping b frames This caused mpv (and possibly others) to fallback to software decoding after seeking a VC1 stream. Bug-Id: 667 Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	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
Vittorio Giovara	c611148340	vc1dec: fix a possible unitialized variable warning	11 years ago
Rémi Denis-Courmont	654c7446a8	vc1dec: improve hwaccel #ifdefs	11 years ago
Vittorio Giovara	6f6c029464	lavc: drop ff_pixfmt_list_420	11 years ago
Vittorio Giovara	e0c16e4e32	mpegvideo: move mpegvideo formats-related defines to mpegutils.h	11 years ago
Anton Khirnov	ebfe622bb1	mpegvideo: drop support for real (non-emulated) edges Several decoders disable those anyway and they are not measurably faster on x86. They might be somewhat faster on other platforms due to missing emu edge SIMD, but the gain is not large enough (and those decoders relevant enough) to justify the added complexity.	11 years ago
Michael Niedermayer	d8fd183683	vc1: Fix mb_height for field pictures Tables are always allocated now with sufficient space for either progressive or interlaced content. The alternative would be to detect a change and reallocate. This fixes decoding of a sample. Signed-off-by: Martin Storsjö <martin@martin.st>	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
Anton Khirnov	ac1fc92ea4	vc1dec: move setting repeat_pict after frame_start() has been called. This will allow removing the hacks where each decoder sets current_picture_ptr on its own.	11 years ago
Anton Khirnov	de4ec972c0	vc1: fix a memleak. Happens on a B-frame when neither low_delay nor last_picture_ptr is set (probably corrupted streams only). Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	11 years ago
Anton Khirnov	6792559f8a	vc1: use the AVFrame API properly.	11 years ago
Ronald S. Bultje	458446acfa	lavc: Edge emulation with dst/src linesize Allow supporting files for which the image stride is smaller than the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago
Luca Barbato	08303d7741	hwaccel: Simplify ff_find_hwaccel It is always called by passing fields from an AVCodecContext.	11 years ago
Diego Biurrun	b2bed9325d	cosmetics: Group .name and .long_name together in codec/format declarations	11 years ago
Martin Storsjö	23d6ba2c44	vc1dec: Check the error handling flags on slice/field header decode errors Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Michael Niedermayer	bb7bf17595	vc1dec: Don't decode slices when the latest slice header failed to decode Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	5e25fdbfe0	vc1dec: Make sure last_picture is initialized in vc1_decode_skip_blocks Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	b772b0e28e	vc1dec: Undo mpegvideo initialization if unable to allocate tables Previously, s->context_initialized was left set to 1 if ff_vc1_decode_init_alloc_tables failed, skipping the initialization completely on the next decode call. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	ede508443e	vc1dec: Fix leaks in ff_vc1_decode_init_alloc_tables on errors Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
