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.

Luca Barbato	6258d362b8	ac3: Do not clash with normal AVERROR The parsing function return AVERROR and AAC_AC3_PARSE_ERROR values, make sure they are not misunderstood.	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	13 years ago
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. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

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.
