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	d6604b29ef	Gather all coded_frame allocations and free functions to a single place Allocating coded_frame is what most encoders do anyway, so it makes sense to always allocate and free it in a single place. Moreover a lot of encoders freed the frame with av_freep() instead of the correct API av_frame_free(). This bring uniformity to encoder behaviour and prevents applications from erroneusly accessing this field when not allocated. Additionally this helps isolating encoders that export information with coded_frame, and heavily simplifies its deprecation. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago

Paul B Mahol	7e52080cb1	pcm: support 24-bit/32-bit little-endian planar Used by LXF. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Christian Schmidt	a42e3a6700	pcm_dvd: consolidate pieces from pcm.c and mpeg.c Remove the header decoding for PCM audio from mpeg.c and the 20/24bit parts from pcm.c and merge them into a new decoder in pcm-dvd.c. The decoder has added support for samples that span multiple packets and modified 20/24bit group decoding. Both is needed to decode samples that have been generated with DVD-Lab Pro 2. The decoding of 16bit PCM and two channel 24bit is identical to before. No other samples are known to verify the correctness of the encoding this software does. The complete list of tested formats is 48kHz/16bit/2-8 channels 48kHz/24bit/2-5 channels 96kHz/16bit/2-4 channels 96kHz/24bit/2 channels Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago

Justin Ruggles	00dd9a6d6a	pcm: fix decoding of pcm_s16le_planar on big-endian The sample count is decremented by the DECODE() macro and needs to be reset in each loop iteration. Also, DECODE() increments the src pointer so that does not need to be done separately.	12 years ago
