Justin Ruggles	4a6a29a7fb	libopencore-amr: check output buffer size before decoding	13 years ago
Justin Ruggles	345d15d2f9	libopencore-amr: remove unneeded buf_size==0 check. avcodec_decode_audio3() already checks it before sending the packet to the decoder.	13 years ago
Justin Ruggles	402c98783d	libopencore-amr: remove unneeded frame_count field. Use AVCodecContext.frame_number instead.	13 years ago
Justin Ruggles	71ccfb3f14	aac_latm: remove unneeded check for zero-size packet. This is already checked by avcodec_decode_audio3()	13 years ago
Justin Ruggles	f1901180e0	pcmdec: fix output buffer size check by calculating the actual output size prior to decoding.	13 years ago
Justin Ruggles	154cd253e5	pcmdec: move codec-specific variable declarations to the corresponding codec blocks.	13 years ago
Justin Ruggles	0093f96d34	pcmdec: return buf_size instead of src-buf. The values will always be the same, so this change eliminates an unneeded variable. It also gets rid of the need to reset src when memcpy() is used.	13 years ago
Justin Ruggles	85579b6381	avcodec: remove the Zork PCM encoder. The Zork PCM decoder does not decode the 1 sample we have correctly, therefore the encoder based on the decoder is also incorrect. There is no good reason to keep the encoder.	13 years ago
Justin Ruggles	67a3b67c71	pcm_zork: use AV_SAMPLE_FMT_U8 instead of shifting all samples by 8.	13 years ago
Justin Ruggles	06af335a33	pcmenc: remove unneeded sample_fmt check. It is already checked by avcodec_open2().	13 years ago
Justin Ruggles	d94e29cac9	pcmdec: move number of channels check to pcm_decode_init()	13 years ago
Justin Ruggles	83efd7652e	pcmdec: remove unnecessary check for sample_fmt change	13 years ago
Justin Ruggles	381e195b46	pcmdec: move DVD PCM bits_per_coded_sample check near to the code that sets the sample size.	13 years ago
Justin Ruggles	6b94711f15	pcmdec: do not needlessly set *data_size to 0	13 years ago
Justin Ruggles	30f3e7b524	alacdec: remove unneeded NULL or zero-size packet checks. This is already done in avcodec_decode_audio3()	13 years ago
Justin Ruggles	68f7e9cd8e	alacdec: simplify buffer allocation by using FF_ALLOC_OR_GOTO()	13 years ago
Justin Ruggles	b316af7a7c	alacdec: ask for a sample for unsupported sample depths. Also return AVERROR_PATCHWELCOME.	13 years ago
Justin Ruggles	63cf54df7a	alacdec: cosmetics: use 'ch' instead of 'chan' to iterate channels	13 years ago
Justin Ruggles	01200f1283	alacdec: move some declarations to the top of the function	13 years ago
Justin Ruggles	c3a92412c0	alacdec: always use get_sbits_long() for uncompressed samples	13 years ago
Justin Ruggles	b46e58f741	alacdec: remove unneeded local variable	13 years ago
Justin Ruggles	7080533cda	alacdec: remove the numchannels parameter from several functions. They only operate on stereo content, so the extra param is not necessary and also allows for simplifying the code.	13 years ago
Justin Ruggles	cb50329fc5	alacdec: rename 2 functions. Now they only do stereo interleaving.	13 years ago
Justin Ruggles	c39bddd392	alacdec: move appending of extra_bits to a separate function. This should also fix decoding of mono 24-bit.	13 years ago
Justin Ruggles	e739d35156	alacdec: split stereo decorrelation into a separate function. It is identical for 16-bit and 24-bit, so there is no need to have duplicate code.	13 years ago
Justin Ruggles	d251c85dce	alacdec: cosmetics: rename 'wasted_bits' to 'extra_bits'. The bits are not wasted, they are additional low bits that are added to the 16-bit decompressed samples to increase the output sample depth.	13 years ago
Justin Ruggles	dbbb9262ca	alacdec: remove unneeded numsamples checks	13 years ago
Justin Ruggles	53df079a73	alacdec: check for buffer allocation failure. Also rearranges some functions for easier cleanup on failure.	13 years ago
Justin Ruggles	e5e4f92b5c	alacdec: allocate per-channel buffers based on channel count. reduces memory usage when the stream has fewer than MAX_CHANNELS	13 years ago
Justin Ruggles	dcaa83a0fc	alacdec: read/validate number of channels from the extradata. check frame header channel count against header/container channel count.	13 years ago
Justin Ruggles	47e9c75b36	alacdec: remove unneeded validation of setinfo_sample_size. It is already done when using it to set sample_fmt.	13 years ago
Justin Ruggles	0f26f3d5c4	alacdec: set sample_fmt in alac_decode_init()	13 years ago
Justin Ruggles	aec8383348	alacdec: set bytespersample using av_get_bytes_per_sample()	13 years ago
Janne Grunau	d6174bfe5f	threads: restore has_b_frames in frame_thread_free Otherwise the delay expressed in has_b_frames increases with every avcodec_close/avcodec_open. Fixes fate-ea-dct with more than 1 thread.	13 years ago
Daniel Kang	ded3e9f054	H.264: Cometics to dsputil_mmx.c Add whitespace. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Justin Ruggles	a3a8572165	g722dec: check output buffer size before decoding	13 years ago
Justin Ruggles	4e41973794	g722dec: cosmetics: reindent/linewrap	13 years ago
Justin Ruggles	d0a196962a	g722dec: remove the use of lowres for half-rate decoding. It is broken because an AVCodecContext can be opened/closed multiple times, and sample_rate is getting divided by 2 each time that happens. This removes the only use of lowres for audio.	13 years ago
Justin Ruggles	f540ca22c5	tta: check for extradata allocation failure in tta demuxer	13 years ago
Justin Ruggles	2f1d212fd0	tta: check for allocation failure of decode_buffer	13 years ago
Justin Ruggles	b5050539c9	tta: use correct frame_length calculation. using a floating-point calculation is not necessary.	13 years ago
Justin Ruggles	c6056d4004	tta: add support for decoding 24-bit sample format Note that this will not work in most cases with avconv and avplay due to the AVCODEC_MAX_AUDIO_FRAME_SIZE limit, but it will decode correctly if given a large enough output buffer.	13 years ago
Justin Ruggles	8664682d0e	cosmetics: indentation	13 years ago
Justin Ruggles	7b7a74a150	tta: remove pointless braces	13 years ago
Justin Ruggles	e6923f683c	tta: check output buffer size after adjusting frame length for last frame	13 years ago
Justin Ruggles	b16960a8a5	tta: fix reading of format in TTA header. TTA does not support float at all, and format 2 is encrypted TTA.	13 years ago
Justin Ruggles	4d3e7a7516	tta: remove useless commented-out lines	13 years ago
Justin Ruggles	35f9d8c20a	tta: check remaining bitstream size while reading unary value	13 years ago
Anton Khirnov	3d813e4c54	lavf: deprecate AVStream.stream_copy It's only used in avconv, so it properly belongs to OutputStream struct there.	13 years ago
Anton Khirnov	1b648c7cdb	avconc: split choose_codec() to choose_decoder/choose_encoder. Prevents -c copy from working for input streams and allows to move stream_copy variable from AVStream to OutputStream.	13 years ago
