Anton Khirnov	b513bf6f69	yuv4mpegdec: do not set coded_frame properties coded_frame is not meant to be changed from outside of lavc, and is not used for decoding. Set AVCodecContext.field_order instead.	11 years ago
Anton Khirnov	e4dc1000d7	yuv4mpeg: split the demuxer and muxer into separate files	11 years ago
Anton Khirnov	3ef6c5264b	a64: check that extradata exists before reading from it	11 years ago
Anton Khirnov	b136564909	a64: remove unneeded struct qualifier	11 years ago
Anton Khirnov	d256ed78ff	4xm: allocate extradata properly. Pad it with the required amount of zeros, check for malloc failure.	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
nu774	584f884090	riff: Pass block_align to estimate frame duration Fix incorrect wSamplesPerBlock(=0) written for ADPCM_IMA_WAV Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Martin Storsjö	34e2ce5dde	hlsenc: Set the default codecs to AAC and H264 Most HLS implementation only support these codecs. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Katerina Barone-Adesi	4d25c2bc76	build: Support building using clang-usan and disable-optimization Clang Undefined Behaviour Sanitizer seems to make non-constant constant expressions, making the compilation fail when they are used within inline assembly if no optimization is requested. Add -O1 to the cflags to hide the misbehaviour. Bug-Id: 683	11 years ago
Hendrik Leppkes	7c377f0e74	avisynth: set duration of audio streams Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Anton Khirnov	4735784f1c	FATE/opus: increase fuzz for the celt tests This seems to be needed on some 32bit arches.	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
Tristan Matthews	7c5ca546a0	configure: fix enable-libopus help string	11 years ago
Janne Grunau	5e2ba41d4b	build: add avresample after avcodec to FFLIBS avcodec might depend on avresample and with --as-needed required symbols might be get removed if avresample is linked before avcodec. Fixes link failures of avprobe and avplay on aarch64 with --enable-neon-clobber-test.	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	c9281a01b7	lavf: drop the zero-sized packets hack There should not be any valid reason anymore for passing completely empty packets to lavf. OTOH side data-only packets can be useful.	11 years ago
Anton Khirnov	0c1959b056	lavf: add AVFMT_FLAG_BITEXACT. Use it instead of checking CODEC_FLAG_BITEXACT in the first stream's codec context. Using codec options inside lavf is fragile and can easily break when the muxing codec context is not the encoding context.	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	7e90133f64	build: do not append $(FFLIBS-) to $(FFLIBS) if $(NAME) is not defined Avoids including disabled library Makefiles.	11 years ago
Anton Khirnov	a738540366	lavf: properly document the distinction between flags and ctx_flags	11 years ago
Janne Grunau	449511740f	build: handle library dependencies in configure Instead of setting FFLIBS in each library Makefile configure exports FFLIBS-$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	1839fafa95	avconv: Support VDA hwaccel Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	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	66e6c8a7b4	lavu: Add a pixel format for new VDA hwaccel The current hwaccel is broken and cannot be fixed in a compatible way. It will be deprecated and replaced with a new one.	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	0bacfa8d37	rtmpproto: Check the buffer sizes when copying app/playpath strings As pointed out by Reimar Döffinger. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Uwe L. Korn	7ce3bd9614	rtmpproto: Support alternative slist parameter in rtmp URLs Support the URL scheme where the playpath is in an RTMP URL is passed as the slist argument and the app is given infront of the query part of the URL: rtmp://host[:port]/[app]?slist=[playpath] (other arguments in the query part are stripped as they are not used) Signed-off-by: Martin Storsjö <martin@martin.st>	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	9580818c5d	avconv: rename OutputStream.opts to OutputStream.encoder_opts This makes it more clear what is this variable for exactly.	11 years ago
Anton Khirnov	01947f07b8	avconv: remove a useless line Doing anything with that field when we are doing streamcopy (so the encoder is not opened) should have absolutely no effect.	11 years ago
Anton Khirnov	65ed9e7585	avconv: rename 'codec' to 'enc_ctx' This more clearly describes what is the variable used for. Also, move its declaration into the block where it is actually used.	11 years ago
Anton Khirnov	650a5206a9	avconv: rename 'icodec' to 'dec_ctx' This more clearly describes what is the variable used for.	11 years ago
Anton Khirnov	f3a6ad22c9	avconv: rename InputStream.opts to InputStream.decoder_opts This makes it more clear what is this variable for exactly.	11 years ago
Anton Khirnov	73ed8558a6	avconv: simplify exit_program() by using more local vars	11 years ago
