Jiejun Zhang	677701c6b3	lavc/audiotoolboxenc: fix noise in encoded audio This fixes #6940 Although undocumented, AudioToolbox seems to require the data supplied by the callback (i.e. ffat_encode_callback) being unchanged until the next time the callback is called. In the old implementation, the AVBuffer backing the frame is recycled after the frame is freed, and somebody else (maybe the decoder) will write into the AVBuffer and change the data. AudioToolbox then encodes some wrong data and noise is produced. Retaining a frame reference solves this problem. Signed-off-by: James Almer <jamrial@gmail.com>	7 years ago
wm4	b945fed629	avcodec: add metadata to identify wrappers and hardware decoders Explicitly identify decoder/encoder wrappers with a common name. This saves API users from guessing by the name suffix. For example, they don't have to guess that "h264_qsv" is the h264 QSV implementation, and instead they can just check the AVCodec .codec and .wrapper_name fields. Explicitly mark AVCodec entries that are hardware decoders or most likely hardware decoders with new AV_CODEC_CAPs. The purpose is allowing API users listing hardware decoders in a more generic way. The proposed AVCodecHWConfig does not provide this information fully, because it's concerned with decoder configuration, not information about the fact whether the hardware is used or not. AV_CODEC_CAP_HYBRID exists specifically for QSV, which can have software implementations in case the hardware is not capable. Based on a patch by Philip Langdale <philipl@overt.org>. Merges Libav commit `47687a2f8a`.	7 years ago
Rick Kern	143685a42b	lavc/audiotoolboxenc: fix dropped frames on iOS AudioConverterFillComplexBuffer() doesn't always call its callback. A frame queue is used to prevent skipped audio samples. Signed-off-by: Rick Kern <kernrj@gmail.com>	9 years ago
Rodger Combs	36770d8769	lavc/audiotoolboxenc: allow setting maxrate with pre-10.9 deployment targets The build failure here is caused by the enum value not being defined, but as long as we're on a newer SDK that has it, it's safe to use it even when our deployment target is older. Setting the property will error, but we're not failing on errors there.	9 years ago

Rodger Combs	c820e600ea	lavc/audiotoolboxenc: fix a number of config issues - size variables were used in a confusing way - incorrect size var use led to channel layouts not being set properly - channel layouts were incorrectly mapped for >2-channel AAC - bitrates not accepted by the encoder were discarded instead of being clamped - some minor style/indentation fixes	9 years ago
Rodger Combs	7524b67817	lavc/audiotoolboxenc: remove unneeded packet metadata This isn't necessary here, and for some reason broke only multichannel AAC encoding when a channel layout tag was set.	9 years ago
Dan Dennedy	28688d7c2b	avcodec/audiotoolboxenc: Fix compile error on OS X 10.8. Fixes error "libavcodec/audiotoolboxenc.c:294:50: error: use of undeclared identifier 'kAudioCodecPropertyPacketSizeLimitForVBR'."
