Andreas Rheinhardt	ae937c4902	avcodec/aac_ac3_parser: Untangle AAC and AC3 parsing error codes Also remove the (unused) AAC_AC3_PARSE_ERROR_CHANNEL_CFG while at it; furthermore, fix the documentation of ff_ac3_parse_header() and (ff\|avpriv)_adts_header_parse().

James Almer	4c35bb53f9	avcodec/ac3_parser: improve false positive detection when parsing sync frames A two byte sync word is not enough to ensure we got a real syncframe, nor are all the range checks we do in the first seven bytes. Do therefore an integrity check for the sync frame in order to prevent the parser from filling avctx with bogus information. Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
James Almer	b5abf6fdfc	avcodec/aac_ac3_parser: don't fill stream info in the sync function Have it only find frame boundaries. The stream props will then be filled once we have an assembled frame. Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
Alexander Strasser	ecd71916d1	lavc/aac_ac3_parser: fix potential overflow when averaging bitrate The new code is analog to how it's done in our mpegaudio parser. Acked-by: Jun Zhao <barryjzhao@tencent.com> Signed-off-by: Alexander Strasser <eclipse7@gmx.net>	4 years ago
Jun Zhao	60d79b1df9	lavc/aac_ac3_parser: improve the raw AAC file bit rate calculation Now we just use one ADTS raw frame to calculate the bit rate, it's lead to a larger error when get the duration from bit rate, the improvement cumulate Nth ADTS frames to get the average bit rate. e,g used the command get the duration like: ffprobe -show_entries format=duration -i fate-suite/aac/foo.aac before this improvement dump the duration=2.173935 after this improvement dump the duration=1.979267 in fact, the real duration can be get by command like: ffmpeg -i fate-suite/aac/foo.aac -f null /dev/null with time=00:00:01.97 Also update the fate-adtstoasc_ticket3715.

Mans Rullgard	cc276c85d1	Make channel layout masks unsigned It makes more sense for a bit mask to use an unsigned type. The change should be source and binary compatible on all supported systems, hence micro version bump. Fixes a few invalid shifts. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name.

Philip Gladstone	2727c35ed7	* Made encoding to ASF streams work again. It turns out that the default stream id that AVI wants for MSMPEG4V3 doesn't work for ASF. I have added a flag to indicate that certain tags should not be used in ASF streams. I think that this is the wrong solution (just adding a flag for ASF), but it does work.
