Michael Niedermayer	cf4d050b72	avformat/wavdec: Remove direct s->pb->buffer access Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Derek Buitenhuis	fcbdc44f4e	wavdec: Only set the codec ID in read_header WAV is not a NOHEADER format, and thus should not be changing stream codec IDs and probing in read_packet.

Michael Niedermayer	de0bcea664	avcodec/mjpegdec: Do not permute quantization tables This fixes issues if the permutation changes, as quantizations tables would need to be reread Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Marios Titas	c1f9734f97	avfilter/src_movie: fix how we check for overflows with seek_point Currently, if the movie source filter is used and a seek_point is specified on a file that has a negative start time, ffmpeg will fail. An easy way to reproduce this is as follows: $ ffmpeg -vsync passthrough -filter_complex 'color=d=10,setpts=PTS-1/TB' test.mp4 $ ffmpeg -filter_complex 'movie=filename=test.mp4:seek_point=2' -f null - The problem is caused by checking for int64_t overflow the wrong way. In general, to check whether a + b overflows, it is not enough to do: a > INT64_MAX - b because b might be negative; the correct way is: b > 0 && > a > INT64_MAX - b Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Hendrik Leppkes	ce87711df5	exif: take a generic log context The AVCodecContext is only used for logging, so instead take any valid log context. This allows reusing the exif functions more easily in avformat. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	9 years ago
Hendrik Leppkes	994412fb9b	avcodec: properly initialize AVCodecParameters profile/level Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	9 years ago
Rodger Combs	4b150fbe1f	lavf/segment: add option to write empty filler segments as needed	9 years ago
Rodger Combs	5b4f44f66a	lavf/segment: slight refactor to seg_write_packet This reduces some code duplication, and ensures that cur_entry.last_duration is always set.	9 years ago
Rodger Combs	44a9395b5a	lavf/segment: style nit	9 years ago
Rick Kern	c9ad357aeb	lavc/videotoolboxenc: Workaround encoder error CMVideoFormatDescriptionGetH264ParameterSetAtIndex() fails on some hardware/OS versions when retrieving the parameter set count alone. Signed-off-by: Rick Kern <kernrj@gmail.com> Signed-off-by: wm4 <nfxjfg@googlemail.com>	9 years ago
Rick Kern	7801669470	lavc/videotoolboxenc: Fix crash when closing codec after error Fixes crash in #5352. VTCompressionSessionInvalidate() crashes if the internal encoder hasn't completed, but hasn't experienced an error. The function call isn't needed since the encoder is invalidated when the reference count reaches 0 anyway.

Clément Bœsch	ffd1c3eeb7	lavc/utils: use pkt_timebase for legacy subtitles timing code This is consistent with other AVSubtitle timing adjustments.	9 years ago
Clément Bœsch	d8620158c7	lavc/ccaption_dec: remove usage of avctx->time_base lavc/utils already rescales avpkt->pts to sub->pts in AV_TIME_BASE_Q before calling the decode callback. This prevents from rescaling again into the decoder, and avoid the use of avctx->time_base which will disappear in the incoming codecpar merge. This commit also replaces the use of "20 centisecond" (ass time base) with "200 ms".	9 years ago
Stefano Sabatini	e8a9b64410	lavu/base64: add AV_BASE64_DECODE_SIZE() macro This is consistent with the AV_BASE64_SIZE macro and avoids the literal use of constants in the code.	9 years ago
Rodger Combs	b4daa2c40f	lavc/audiotoolboxdec: add eac3 decoder This is added in 10.11, so we add a #define when building against older SDKs. The decoder actually supports 7.1-channel eac3, but since the parser only reports 6 channels, we end up decoding the 5.1 downmix (same as the internal decoder) for now.	9 years ago
Rodger Combs	1b9e90ee80	lavc/audiotoolboxdec: fix a number of config and timestamp issues - ADTS-formatted AAC didn't work - Channel layouts were never exported - Channel mappings were incorrect beyond stereo - Channel counts weren't updated after packets were decoded - Timestamps were exported incorrectly	9 years ago
Rodger Combs	59a4492371	lavc/audiotoolboxdec: support ADTS AAC input	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	0667327f3f	lavc/audiotoolboxenc: fix iOS build	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
Rodger Combs	d38fe9f493	lavf/segment: support automatic bitstream filtering Most useful for MPEG-TS. Works by having the underlying muxer configure the bitstream filters, then moving them to our own AVStreams.	9 years ago

Ronald S. Bultje	98038e2ee0	swscale: fix bt709 yuv2rgb coefficients. They were derived from incorrect values cr=0.2125 (should be cr=0.2126) and cb=0.0721 (should be cb=0.0722).	9 years ago
