Hendrik Leppkes	ed4b757177	dxva2_h264: add a workaround for old Intel GPUs Old Intel GPUs expect the reference frame index to the actual surface, instead of the index into RefFrameList as specified by the spec. This workaround should be set when using one of the "ClearVideo" decoder devices. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Hendrik Leppkes	2fcef90bee	dxva2_h264: set the correct ref frame index in the long slice struct The latest H.264 DXVA specification states that the index in this structure should refer to a valid entry in the RefFrameList of the picture parameter structure, and not to the actual surface index. Fixes H.264 DXVA2 decoding on recent Intel GPUs (tested on Sandy and Ivy) Signed-off-by: Anton Khirnov <anton@khirnov.net>	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

Michael Niedermayer	1c7b71a5bd	mpegvideo: Use the current_picture pts The picture slot can be recycled by select_input_picture and only current_picture is populated with the valid pts. Unbreak timestamps when in cbr mode. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago

Janne Grunau	34c5a6660a	h264: codec reinit: remove statements without effect avctx->coded_{height,width} will always equal h->{height,width} since init_dimensions() does that explicitly, Size changes are detected by changes in mb_{height,width} earlier and propagated through the needs_reinit variable.	11 years ago

Martin Storsjö	a6ac4fcce4	vp78: Align the intra4x4_pred_mode_top array within VP8Macroblock This array is written using AV_WN32A, assuming alignment. This hopefully fixes the failing vp7 fate test on sparc. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Niels Möller	b3d905b702	dcadec: Delete redundant init_get_bits call No initialization is needed in dca_decode_frame, because the next thing it does is calling dca_parse_frame_header, which takes care of the needed initialization. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago

Justin Ruggles	fdbe18b7b0	tiffdec: use a single strip if RowsPerStrip is 0 The spec does not specify that 0 is an error condition, and there are samples which use 0 when the whole image is in one strip.	11 years ago
Justin Ruggles	0a467a9b59	tiffdec: use bytestream2 to simplify overread/overwrite protection Based on a patch by Paul B Mahol <onemda@gmail.com> CC:libav-stable@libav.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
