Anton Khirnov	9929b3564c	pthread_frame: simplify the code by using new AVPacket API This also handles side data properly.	11 years ago
Anton Khirnov	cdf58f0599	avpacket: fix copying side data in av_packet_copy_props() Side data count is incremented by by calling av_packet_new_side_data() in the following loop, setting it explicitly results in the resulting value being twice what it should be. CC: libav-stable@libav.org	11 years ago

Anton Khirnov	fd056029f4	lavc: add avcodec_free_context(). Right now, the caller has to manually manage some allocated AVCodecContext fields, like extradata or subtitle_header. This is fragile and prone to leaks, especially if we want to add more such fields in the future. The only reason for this behaviour is so that the AVStream codec context can be reused for decoding. Such reuse is discouraged anyway, so this commit is the first step to deprecating it.	11 years ago
Anton Khirnov	e1b66778b6	lavc: remove the locking code in avcodec_close() This function should not modify any global state, so there should be no reason for any locking.	11 years ago
Janne Grunau	d3f5b94762	aarch64: opus NEON iMDCT and FFT Opus celt decoding 11% faster and the iMDCT over 2.5 times faster on Apple's A7.	11 years ago
Anton Khirnov	3b2fbe67bd	lavc: properly handle subtitle_header in avcodec_copy_context()	11 years ago
Anton Khirnov	efc7df6c1f	lavc: preserve the original private data in avcodec_copy_context() If a non-NULL codec was passed to avcodec_alloc_context3(), private data will be already allocated in dest.	11 years ago
Anton Khirnov	b70d7a4ac7	lavc: add a native Opus decoder. Initial implementation by Andrew D'Addesio <modchipv12@gmail.com> during GSoC 2012. Completion by Anton Khirnov <anton@khirnov.net>, sponsored by the Mozilla Corporation. Further contributions by: Christophe Gisquet <christophe.gisquet@gmail.com> Janne Grunau <janne-libav@jannau.net> Luca Barbato <lu_zero@gentoo.org>	11 years ago
Janne Grunau	449511740f	build: handle library dependencies in configure Instead of setting FFLIBS in each library Makefile configure exports FFLIBS-$library in config.mak.	11 years ago
Janne Grunau	9aa4592076	aarch64: assembler in clang-3.4 ignores the division by two Values are positive powers of two, so just replace it with right shift.	11 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
Anton Khirnov	dd2d3b766b	lavc: Add hwaccel private data and init/uninit callbacks	11 years ago
Luca Barbato	ebc29519d1	hwaccel: Support specific frame allocators It would reduce the boilerplate code users have to write.	11 years ago
Anton Khirnov	a871ef0cc9	hwaccel: Rename priv_data_size to frame_priv_data_size This describes more accurately what this field is for.	11 years ago
Anton Khirnov	08bb256758	lavc: document which parts of AVHWAccel are private.	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
nu774	9880a0d4b1	pcm-dvd: Fix 20bit decoding Increment the pointer as needed. Bug-Id: 592 Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Martin Storsjö	3828eb8519	libfdk-aac: Relicense the library wrappers to 2-clause BSD This should make it possible for Fraunhofer to contribute to these wrappers - they didn't want to contribute to code under LGPL2.1 with the "or any later version" clause (which allowed using the code under the LGPL3 license). Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Jean First	15fa856b82	libfdk-aacenc: Enable 7.1 channel encoding 7.1(wide) and 7.1(wide-side) channel layouts are supported in fdk-aac since the 0.1.3 release. The earlier versions of fdk-aac didn't include any library version defines in the public headers, thus checking for the AACENCODER_LIB_VL0 define is enough to know that we're building against a new enough version of fdk-aac. This change includes contributions by Tim Walker, Michael Niedermayer and Timothy Gu. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago

Anton Khirnov	ba71c74017	lavc: deprecate AVCodecContext.codec_name It is undocumented and has no real use.	11 years ago
Anton Khirnov	e7fc9796d8	lavc: do not use AVCodecContext.codec_name in avcodec_string() That field will be deprecated.	11 years ago

Anton Khirnov	5fccedaa67	lavc: deprecate CODEC_FLAG_INPUT_PRESERVED The addition of reference-counted frames makes it pointless.	11 years ago

Anton Khirnov	c1f92d1358	mpegvideo: remove unused MpegEncContext.b4_stride	11 years ago
Anton Khirnov	6a13505c06	mpegvideo: move the MpegEncContext fields used from arm asm to the beginning This should reduce the frequency with which the offsets need to be updated.	11 years ago
Michael Niedermayer	b2b4afe811	hwaccel: fix dxva2 & vaapi loop filter parameters Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
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
