Diego Biurrun	b239526873	vorbisdec: Rename silly "class_" variable to plain "class".	14 years ago
Diego Biurrun	81afa5a274	simple_idct_alpha: Drop some useless casts.	14 years ago
Diego Biurrun	3fd3632ffe	Simplify av_log_missing_feature(). Do not print the results of the conditional call to av_log_ask_for_sample() into the same line as the main output, separate the already long text.	14 years ago
Alexandre Colucci	d6f910ea47	Fix decoding of DXSA subtitles. These have a DXSA tag and contain alpha in addition to color values for palette.	14 years ago
Justin Ruggles	8745e9c458	ac3enc: remove check for mismatching channels and channel_layout	14 years ago
Justin Ruggles	688b09fa59	If AVCodecContext.channels is 0 and AVCodecContext.channel_layout is non-zero, set channels based on channel_layout. This allows the user to set only channel_layout and not channels.	14 years ago
Justin Ruggles	168f9e8c40	If AVCodecContext.channel_layout and AVCodecContext.channels are both non-zero, check to make sure they do not contradict eachother.	14 years ago
Justin Ruggles	3dfc3e70c0	cosmetics: indentation	14 years ago
Justin Ruggles	8b00ab0113	Check AVCodec.supported_samplerates and AVCodec.channel_layouts in avcodec_open(). If the encoder has a channel_layouts list and AVCodecContext.channel_layout is 0, then only print a warning and let the encoder decide how to handle it.	14 years ago
Alex Converse	767848d761	aacdec: remove sf_scale and sf_offset. Instead, scalefactors are adjusted by the offset amount, removing the need for sf_scale, and the MDCT scales are adjusted to compensate for the higher scalefactors. Floating-point output will be handled by modifying the MDCT scales.	14 years ago
Justin Ruggles	6271794041	aacdec: use a scale of 2 in the LTP MDCT rather than doubling the coefficient table values from the spec.	14 years ago
Alex Converse	d70fa4c423	Define POW_SF2_ZERO in aac.h and use for ff_aac_pow2sf_tabp[] offsets instead of hardcoding 200 everywhere.	14 years ago
Alex Converse	e4744b59aa	Large intensity stereo and PNS indices are legal. Clip them instead of erroring out. A magnitude of 100 corresponds to 2^25 so the will most likely result in clipped output anyway. None of the conformance streams fall in the range that need to be clipped.	14 years ago
Michael Niedermayer	f08d171caa	WMADEC: fix ticket125 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Stefano Sabatini	f4e043ff63	qpeg: use reget_buffer() in decode_frame() Decoder relies on previous frame data, so use reget_buffer(). This also set frame->reference to 3, as the frame will be requested unmodified later so it shouldn't be modified by the application. Fix playback of file Clock.avi. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Stefano Sabatini	4f0b80599a	ultimotion: use reget_buffer() in ulti_decode_frame() Decoder relies on previous frame data, so use reget_buffer(). Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Stefano Sabatini	4f2954e232	smacker: remove unnecessary call to avctx->release_buffer in decode_frame() The release_buffer was cleaning the provided frame, thus causing the successive call to avctx->reget_buffer() to allocate a new frame. In case the returned frame was not the same one previously returned but a new one with different data, it resulted in artifacts. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Stefano Sabatini	fd37eac495	indeo2: remove unnecessary release_buffer() call This was preventing reget_buffer() to return a buffer with the same data, which was resulting in playback artifacts. Fix trac issue #116.	14 years ago
Stefano Sabatini	10aa5a6c42	4xm: use reget_buffer() in decode_frame() Also remove unnecessary call to avctx->release_buffer(). reget_buffer is required since apparently the codec needs to be feeded with the previous frame data. Releasing the frame and using get_buffer was working only in the case get_buffer() was returning the old frame data, and resulting in playback artifacts otherwise. Fix trac issue #85.	14 years ago

Stefano Sabatini	ff558d7b01	bfi: store palette data in the context Store palette data in the codec context, do not assume that the frame allocated the first time by avctx->get_buffer will be returned again. This requires to store the palette which comes with the first frame in the context, and copy it to the following frames. Fix trac issue #84.

Michael Niedermayer	76cd98b445	mjpeg: Detect overreads in mjpeg_decode_scan() and error out. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Ronald S. Bultje <rbultje@google.com>	14 years ago
Stefano Sabatini	bebe72f4a0	lavc: deprecate FF__TYPE macros in favor of AV_PICTURE_TYPE_ enums Also deprecate av_get_pict_type_char() in favor of av_get_picture_type_char(). The new enum and av_get_picture_type_char() are defined in libavutil. This allows the use in libavfilter without the need to link against libavcodec.
