Justin Ruggles	4142487d1c	ac3enc: return error if frame+exponent bits are too large instead of using av_assert2(). This can occur in some very rare cases with low bitrates.	14 years ago
Justin Ruggles	987fe2dc55	ac3enc: differentiate between current block and reference block in bit_alloc()	14 years ago
Justin Ruggles	6b2636bba6	ac3enc: simplify exponent_init() by calculating exponent_group_tab[] based on exponent group sizes.	14 years ago
Justin Ruggles	e0b33d479c	ac3enc: simplify stereo rematrixing decision options	14 years ago
Reimar Döffinger	636ee66f1c	Fix data_size handling for AC3 and dca decoders. They use now code identical to the AAC decoder. The AC3 decoder previously did not check the data_size and the dca decoder checked against and set wrong values for float.	14 years ago
Stefano Sabatini	77e9dee8ae	lavc: add a sample_aspect_ratio field to AVFrame The sample aspect ratio is a per-frame property, so it makes sense to define it in AVFrame rather than in the codec/stream context. Simplify application-level sample aspect ratio information extraction, and allow further simplifications.	14 years ago
Stefano Sabatini	1ba5727242	lavc: add a pkt_pos field to AVFrame This is similar to what was done with pkt_pts. This simplifies the operation of extracting the pos information from the AVPacket, and allows further simplifications.	14 years ago
Carl Eugen Hoyos	aba0278e9f	Fix compilation in some cases if the flac decoder was disabled. flac.o implies vorbis_data.o because of flac channel layout.	14 years ago

Mike Scheutzow	e12926393b	Fix decoding of mpegts streams with h264 video that does NOT have b frames One of the causes of this bug is that the h264 parser defaults low_delay to 1, but the h264 codec defaults low_delay to 0. Really Ugly. After many hours of looking at this, I'm still not sure how has_b_frames is intended to behave, but to me the implementation appears way more complicated than it ought to be. My patch relies on the encoder to set an optional field in the SPS. This works for libx264 streams, but I'm not sure that all h264 encoders will set it.	14 years ago
ami_stuff	8556406d38	lavc: lowercase the FRWU codec name This is more consistent with all the other codec names. Signed-off-by: Stefano Sabatini <stefano.sabatini-lala@poste.it>	14 years ago
Philip Langdale	8de45adb37	CrystalHD: Add auto-detection of packed b-frame bug. I still don't fully understand the cause but the difference between the samples that trigger the bug and the samples that don't is that the former uses delay frames and the later uses drop frames as placeholders for the packed frame. So, if we see the one type of frame, we can assume the bug will or won't be present. Right now, I'm detecting the frame types by size, which may not be safe in general, but given the specific codec and file type, I expect any scenario where we encounter these frames where they aren't being used for b-frame packing won't care one way or another whether the work around is in effect or not.

Stefano Sabatini	d5551265f3	lavc: remove disabled avcodec_decode_video() code Fix warning: libavcodec/utils.c: At top level: libavcodec/utils.c:714:5: warning: "FF_API_VIDEO_OLD" is not defined Also fix trac issue #139.	14 years ago
Anton Khirnov	85770f2a26	AVOptions: make default_val a union, as proposed in AVOption2. This breaks API and ABI.	14 years ago
Baptiste Coudurier	97dc86b793	In libx264 wrapper, change wpredp to a codec specific option.	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
