Sebastien Zwickert	11d923d414	avcodec: add new Videotoolbox hwaccel.	9 years ago
Luca Barbato	80f955c908	vda: Check the correct pointer for buffer allocation CC: libav-stable@libav.org Found-By: kropping	10 years ago
Stefano Pigozzi	e7c5e17d4f	vda: Make output CVPixelBuffer format configurable This is useful for client programs to ask for nv12 surfaces instead of the current default (uyvy), since those are more efficient to decode to. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Anton Khirnov	a0f2946068	h264: use properly allocated AVFrames	10 years ago
Michael Niedermayer	c299fbbb22	avcodec/vda_h264: try to fix build Found-by: Stefano Pigozzi Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Rainer Hochecker	3e53211a57	vda: fix h264 decoding for avcC,vda wants the entire buffer Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Stefano Pigozzi	2cef68da69	vda: error out if decoded CVPixelBuffer is empty On some video samples, VDA silently fails to decode frames and returns kVDADecoderNoErr. Error out in these cases to avoid producing AVFrames with empty planes. Signed-off-by: Stefano Pigozzi <stefano.pigozzi@gmail.com>	10 years ago

Anton Khirnov	67afcefb35	lavc: Add new VDA hwaccel It leverages the new hwaccel 1.2 features: - get_buffer2 is never called - the internal context is automatically initialized/deinitialized Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Anton Khirnov	31a46750c7	vda: use hwaccel private data for internal bitstream buffer	11 years ago
Xidorn Quan	31a0ca9e75	vda: fix crash when a frame is dropped. Signed-off-by: Sebastien Zwickert <dilaroga@gmail.com>	11 years ago
Michael Niedermayer	4fb1221e66	h264: reduce whitespace differences to libav Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Xidorn Quan	ffd7fd7944	avcodec/vda_h264: use av_buffer to manage buffers This patch fixes a leak of buffer when seeking occurs. It adds a flag in struct vda_context for compatibility with apps which currently use it. If the flag is not set, the hwaccel will behave like before.

Diego Biurrun	c57a593670	hwaccel: consistent name prefixes for start_frame/end_frame/decode_slice Some hwaccels use name prefixes, some do not, others only use them for some codecs. Add prefixes everywhere for consistency.	12 years ago
Anton Khirnov	2c54155407	h264: deMpegEncContextize Most of the changes are just trivial are just trivial replacements of fields from MpegEncContext with equivalent fields in H264Context. Everything in h264* other than h264.c are those trivial changes. The nontrivial parts are: 1) extracting a simplified version of the frame management code from mpegvideo.c. We don't need last/next_picture anymore, since h264 uses its own more complex system already and those were set only to appease the mpegvideo parts. 2) some tables that need to be allocated/freed in appropriate places. 3) hwaccels -- mostly trivial replacements. for dxva, the draw_horiz_band() call is moved from ff_dxva2_common_end_frame() to per-codec end_frame() callbacks, because it's now different for h264 and MpegEncContext-based decoders. 4) svq3 -- it does not use h264 complex reference system, so I just added some very simplistic frame management instead and dropped the use of ff_h264_frame_start(). Because of this I also had to move some initialization code to svq3.
