Michael Niedermayer	7404f3bdb9	lavc: Switch bitrate to 64bit unless compatibility with avconv was requested.	9 years ago
Michael Niedermayer	e36db49b7b	avcodec: Add a min size parameter to ff_alloc_packet2() This parameter can be used to inform the allocation code about how much downsizing might occur, and can be used to optimize how to allocate the packet Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Vittorio Giovara	83797da6e3	wma: Check memory allocation	10 years ago
Michael Niedermayer	8559a71415	avcodec/wmaenc: Check extradata allocations Fixes CID1257842 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	2fbb9e647c	avcodec/wma: Use avpriv_float_dsp_alloc() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Anton Khirnov	2df0c32ea1	lavc: use a separate field for exporting audio encoder padding Currently, the amount of padding inserted at the beginning by some audio encoders, is exported through AVCodecContext.delay. However - the term 'delay' is heavily overloaded and can have multiple different meanings even in the case of audio encoding. - this field has entirely different meanings, depending on whether the codec context is used for encoding or decoding (and has yet another different meaning for video), preventing generic handling of the codec context. Therefore, add a new field -- AVCodecContext.initial_padding. It could conceivably be used for decoding as well at a later point.	10 years ago

Diego Biurrun	b2bed9325d	cosmetics: Group .name and .long_name together in codec/format declarations	11 years ago
Michael Niedermayer	5936d98244	avcodec/wmaenc: change commented assert to av_assert Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Reimar Döffinger	dccaad3bcd	wamenc: handle failure to encode. This is necessary since the switch to floating point input means there is no longer sufficient input data validation. There is a good chance that other encoders are affected by similar issues. This problem can be triggered by trying to encode extremely large values and probably also with Inf and possibly also NaNs.

Diego Biurrun	6fee1b90ce	avcodec: Add av_cold attributes to init functions missing them	12 years ago

James Zern	bcaf64b605	normalize calls to ff_alloc_packet2 - check ret < 0 - remove excessive error log Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Justin Ruggles	205a95f7b5	wmaenc: alloc/free coded_frame instead of keeping it in the WMACodecContext	12 years ago
Ronald S. Bultje	42d3246948	floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp. Now, nellymoserenc and aacenc no longer depends on dsputil. Independent of this patch, wmaprodec also does not depend on dsputil, so I removed it from there also.	12 years ago
Piotr Bandurski	5381960501	wmaenc: add new line to some error messages Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Justin Ruggles	284ea790d8	dsputil: move vector_fmul_scalar() to AVFloatDSPContext in libavutil	12 years ago
Justin Ruggles	2ed40608e9	wma: do not keep private copies of some AVCodecContext fields channels, sample_rate, bit_rate, and block_align can be used directly from the AVCodecContext	12 years ago
Justin Ruggles	31b2262dca	wmaenc: use float planar sample format	12 years ago
Diego Biurrun	6f6b0311a3	avcodec: Drop some silly commented-out av_log() invocations	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	12 years ago
Michael Niedermayer	fbdb205968	wmaenc: dont mess with the bitrate. The bitrate is not writeable by an encoder. Fixes generation of invalid wma Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	9eb6e5cc48	wmaenc: switch all remaining asserts to av_asserts Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Paul B Mahol	137e80817d	lavc: build some codecs only if they are actually enabled Saves few bytes if only some of them in same file are enabled. Signed-off-by: Paul B Mahol <onemda@gmail.com>	13 years ago
Martin Storsjö	00c3b67b8a	cosmetics: Align codec declarations Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Justin Ruggles	27bacfeb57	wmaenc: use AVCodec.encode2()	13 years ago
Justin Ruggles	c3da9f5060	wmaenc: remove bit-exact hack It may have improved cross-platform stability, but wasn't the only place in the encoder with bitexact issues. It is no longer needed because we have FATE tests for float encoders using fuzzy comparison.	13 years ago
Michael Niedermayer	0a7bf34042	wmaenc: change some asserts to av_assert0. This ensures they are always checked Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	0d92e5a682	wmaenc: add assert to check encode_superframe() return. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	c99bd29462	Revert "wmaenc: check final frame size against output packet size" This condition cannot happen, if it can it is a bug that MUST be fixed. And i very happily volunteer to fix it if someone reports a case to me that fails. This reverts commit `5d652e063b`.	13 years ago
Justin Ruggles	51ddf35c90	wmaenc: fix m/s stereo encoding for the first frame We need to set ms_stereo in encode_init() in order to avoid incorrectly encoding the first frame as non-m/s while flagging it as m/s. Fixes an uncomfortable pop in the left channel at the start of playback. CC:libav-stable@libav.org	13 years ago
Justin Ruggles	8ed7488ea3	wmaenc: return s->block_align instead of recalculating it	13 years ago
Justin Ruggles	5d652e063b	wmaenc: check final frame size against output packet size Currently we have an assert() that prevents the frame from being too large, but it is more user-friendly to give an error message instead of aborting on assert(). This condition is quite unlikely due to the minimum bit rate check in encode_init(), but it is still worth having.	13 years ago
Justin Ruggles	dfc4fdedf8	wmaenc: require a large enough output buffer to prevent overwrites The maximum theoretical frame size is around 17000 bytes. Although in practice it will generally be much smaller, we require a larger buffer just to be safe. CC: libav-stable@libav.org	13 years ago
Justin Ruggles	1ec075cfec	wmaenc: limit allowed sample rate to 48kHz ff_wma_init() allows up to 50kHz, but this generates an exponent band size table that requires 65 bands. The code assumes 25 bands in many places, and using sample rates higher than 48kHz will lead to buffer overwrites. CC:libav-stable@libav.org	13 years ago
Justin Ruggles	c2b8dea182	wmaenc: limit block_align to MAX_CODED_SUPERFRAME_SIZE This is near the theoretical limit for wma frame size and is the most that our decoder can handle. Allowing higher bit rates will just end up padding each frame with empty bytes. Fixes invalid writes for avconv when using very high bit rates. CC:libav-stable@libav.org	13 years ago
Anton Khirnov	9f51c682ee	lavc: use avpriv_ prefix for ff_copy_bits and align_put_bits. They are used in lavf.	13 years ago

Mans Rullgard	26f548bb59	fft: remove inline wrappers for function pointers This removes the rather pointless wrappers (one not even inline) for calling the fft_calc and related function pointers. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Diego Elio Pettenò	e7e2df27f8	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `d36beb3f69`)	14 years ago
