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

Michael Niedermayer	90539cea33	avcodec/error_resilience: check that er is supported before attempting to read the status of the previous slice Fixes incorrectly set error_occured and improves speed Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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.

Michael Niedermayer	6005ab3e0e	avcodec/mjpegenc: use av_log2_16bit() in encode_block() This reduces the number of operations done per non zero coefficient Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	b73a8922d8	ljpegenc: split yuv encoding into a separate function	11 years ago
Anton Khirnov	fa4476815d	ljpegenc: split bgr encoding into a separate function	11 years ago
Anton Khirnov	daffed3b17	ljpegenc: accept bgr24 instead of bgra The alpha plane is not encoded.	11 years ago
Anton Khirnov	0cdbc4d393	ljpegenc: rename the encoding function. The new name is more consistent with the rest of Libav.	11 years ago
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
Anton Khirnov	86eb2eaac6	mjpegenc: do not pass MpegEncContext to ff_mjpeg_encode_dc() This will allow deMpegEncContextizing the LJPEG encoder.	11 years ago
Anton Khirnov	3360ad9955	mjpegenc: do not pass MpegEncContext to ff_mjpeg_encode_picture_trailer() This will allow deMpegEncContextizing the LJPEG encoder.	11 years ago
Anton Khirnov	058d5f2feb	mjpegenc: do not pass MpegEncContext to ff_mjpeg_encode_picture_header() This will allow deMpegEncContextizing the LJPEG encoder.	11 years ago
Anton Khirnov	6d70639c7d	mjpegenc: do not pass MpegEncContext to jpeg_table_header() Pass the three needed fields from it directly. This will allow to deMpegEncContextize the LJPEG encoder.	11 years ago
Anton Khirnov	e1eaaec765	mjpegenc: remove commented out never-to-be-finished WIP cruft	11 years ago
Anton Khirnov	ff506c75b7	mjpegenc: do not pass MpegEncContext to put_huffman_table() It only needs PutBitContext from it, so pass that directly.	11 years ago
Anton Khirnov	a1ba1f20b3	mjpegenc: cosmetics, reformat jpeg_put_comments()	11 years ago
Anton Khirnov	0812f5a40a	mjpegenc: write the JFIF header if the sample aspect ratio is set MpegEncContext.aspect_ratio_info is never set for mjpeg, so this was never written before.	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	282c6a1a0e	mpegvideo: make ff_release_unused_pictures() static It is only called from one place in mpegvideo.c now. Also remove the remove_current parameter, which is always 1.	11 years ago
Anton Khirnov	c99307caee	mpegvideo: make frame_size_alloc() static. It is not called from outside of mpegvideo.c anymore.	11 years ago
Anton Khirnov	0b0a7a751d	mpegvideo: move encode-only parts of common_end() to encode_end()	11 years ago
Anton Khirnov	d0d111d059	mpegvideo: remove commented out cruft from ff_MPV_frame_end()	11 years ago
Anton Khirnov	381a722562	mpegvideo: split the encoding-only parts of ff_MPV_frame_end() into a separate function	11 years ago
Anton Khirnov	b7254288d2	mpegvideo: do not update last_non_b_pict_type in update_thread_context() It is used for encoding only.	11 years ago
