anatoly	2fade10cb0	Add support for picture_ptr field in MJpegDecodeContext Signed-off-by: Anton Khirnov <anton@khirnov.net> (cherry picked from commit `e0e3b8b297`) Conflicts: libavcodec/jpeglsdec.c libavcodec/mjpegbdec.c libavcodec/mjpegdec.c Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Diego Biurrun	d64341e498	configure: Prefix libc-related variables with "libc_" Simplifies host/target libc detection splitting.	11 years ago
Alexandra Khirnova	9b8d11a76a	avcodec: Use av_reallocp where suitable Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Anton Khirnov	d4f1188d1a	dv: use AVFrame API properly	11 years ago
John Stebbins	c9ca220ef2	ac3dec: make drc_scale exponentially The a52 spec suggests that "partial compression" should scale the drc value in this manner. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Anton Khirnov	37a749012a	lavc: rework handling of refcounted_frames=0 Use only proper AVFrame API (no assigning of whole frames, since that hardcodes sizeof(AVFrame) into lavc). Make a copy of the side data, so the caller can use av_frame_unref/free on non-refcounted frames, eliminating the need for avcodec_get_frame_defaults()/avcodec_free_frame().	11 years ago
Anton Khirnov	a1ee164869	lavc/decode_video(): always unref the frame if there is no output in decode_video Not just on failure. This is the same thing that is done in the audio path and should prevent leaks in decoders that allocate a frame, but then end up not writing into it.	11 years ago
Anton Khirnov	85f947aefb	lavc: remove a pointless check in decode_audio4() av_frame_unref() works fine on unallocated frames.	11 years ago
Anton Khirnov	d4f0f2d1e8	lavc: use buf[0] instead of data[0] as the indicator of an allocated frame data[0] may be NULL for valid frames with hwaccel pixel formats.	11 years ago
Anton Khirnov	e5419709f5	lavc: remove the extended_data workarounds. All decoders should now handle it properly.	11 years ago
Anton Khirnov	d351ef47d0	pthread_frame: use the AVFrame API properly. Remove the extended_data workaround, all decoders should now handle this properly.	11 years ago
Anton Khirnov	b605b123ef	mxpegdec: use the AVFrame API properly.	11 years ago
Anton Khirnov	afa21a12bf	p*menc: use the AVFrame API properly.	11 years ago

Michael Niedermayer	7854d2d251	avcodec/ffv1: support adjusting the g vs r + b coefficient in the RCT about 1% better compression Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Diego Biurrun	4958f35a2e	dsputil: Move apply_window_int16 to ac3dsp The (optimized) functions are used nowhere else.	11 years ago

James Almer	ae330070ee	libvpxenc: token_parts is VP8 specific Signed-off-by: James Almer <jamrial@gmail.com> Reviewed-by: James Zern <jzern@google.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Guillaume Martres	9aa053cede	libvpx: do not mark VP9 as experimental when using libvpx >= 1.3.0 Signed-off-by: Diego Biurrun <diego@biurrun.de>	11 years ago
Ronald S. Bultje	92436e8ad9	vp9: implement top/left half (4x4) sub-8x8-IDCT. For that specific case (eob>3&&eob<=12), runtime of idct8x8 goes from 668 to 477 cycles. For all idct8x8, runtime goes from 521 to 490 cycles.	11 years ago
Ronald S. Bultje	b2045c44a9	vp9: split pre-load of 11585x2 out of 1d idct macro. This allows us to load it only once, instead of twice, in this function.	11 years ago
Ronald S. Bultje	f9a0d4c6e0	vp9: minor refactorings in idct ssse3 assembly. Make register usage in macros explicit; change mulsub_2w_4x to use 2 instead of 3 temp registers.	11 years ago
Ronald S. Bultje	8729964b99	vp9: split x86 assembly in two files. (And in future, loopfilter or intra pred could be put in their own respective files also.)	11 years ago

Justin Ruggles	d085f80fa1	webp: add a special case for a huffman table with only 1 symbol The vlc reader cannot handle 0-bit huffman codes. For most situations WebP uses the "simple" huffman coding for this case, but that will only handle symbols up to 255. For the LZ77 distance codes, larger symbol values are needed, so it can happen in rare cases that a normal huffman table is used that only has a single symbol.	11 years ago
Justin Ruggles	f51e3a1971	webp: do not call av_frame_free() on the user-provided frame Fixes double-free on error.	11 years ago
James Almer	56572787ae	Add Windows resource file support for shared libraries Originally written by James Almer <jamrial@gmail.com> With the following contributions by Timothy Gu <timothygu99@gmail.com> * Use descriptions of libraries from the pkg-config file generation function * Use "FFmpeg Project" as CompanyName (suggested by Alexander Strasser) * Use "FFmpeg" for ProductName as MSDN says "name of the product with which the file is distributed" [1]. * Use FFmpeg's version (N-xxxxx-gxxxxxxx) for ProductVersion per MSDN [1]. * Only build the .rc files when --enable-small is not enabled.

Anton Khirnov	72c0b8f724	ljpeg: remove a commented-out line	11 years ago
Anton Khirnov	24abd806ea	ljpegenc: deMpegEncContextize The encoder uses almost none of the mpegvideo infrastructure, only some fields from MpegEncContext. The FATE results change because now an all-zero quant matrix is written into the file. Since it is not used for anything for ljpeg, this should not be a problem.	11 years ago
