Justin Ruggles	e0b33d479c	ac3enc: simplify stereo rematrixing decision options	14 years ago
Michael Niedermayer	7089265756	AMV: disable DR1 and don't override EMU_EDGE This works around a possibly exploitable crash. Appearently, vlc can be exploited with a malicous file. This should get reverted as soon as a proper fix is found.

Diego Biurrun	cf3ac54339	vorbis: Replace sized int_fast integer types with plain int/unsigned. int/unsigned is the natural memory access type for CPUs, using sized types for temporary variables, counters and similar just increases code size and can possibly cause a slowdown.	14 years ago
Diego Biurrun	a734fa575f	Remove disabled non-optimized code variants.	14 years ago
Diego Biurrun	2e15305b70	Remove some disabled printf debug cruft.	14 years ago
Diego Biurrun	09cbf60f8e	Replace more disabled printf() calls by av_dlog().	14 years ago
Diego Biurrun	045dd4b928	Replace some commented-out debug printf() / av_log() messages with av_dlog().	14 years ago
Diego Biurrun	d1be646e90	vorbisdec: Replace some sizeof(type) by sizeof(*variable).	14 years ago
Stefano Sabatini	62d33dbc17	mpeg12: terminate mpeg2_video_profiles arrays Make av_get_profile_name() return NULL if no profile is detected. Fix trac issue #130, fix crash reading file tek3.m2v.

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
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
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.

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	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.
