Anton Khirnov	4227e4fe74	lavf: add a convenience function for adding side data to a stream	10 years ago
Alessandro Ghedini	ae43c10e36	replaygain: allow exporting already decoded replaygain values This adds a function to export raw replaygain values (i.e. in the (u)int32_t form). It first checks whether AV_PKT_DATA_REPLAYGAIN side data is present, in which case it does nothing. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Michael Niedermayer	b97f2c7c49	replaygain: remove unused variable Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Alessandro Ghedini	8542f9c4f1	replaygain: correctly parse peak values According to the ReplayGain spec, the peak amplitude may overflow and may result in peak amplitude values greater than 1.0 with psychoacoustically coded audio, such as MP3. Fully compliant decoders must allow peak overflows. Additionally, having peak values in the 0<->UINT32_MAX scale makes it more difficult for applications to actually use the peak values (e.g. when implementing clipping prevention) since values have to be rescaled down. This patch corrects the peak parsing by removing the rescaling of the decoded values between 0 and UINT32_MAX and the 1.0 upper limit. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Alessandro Ghedini	25b6837f7c	replaygain: fix gain sign decoding The gain sign was incorrectly decoded: since the FFSIGN() macro treats 0 as negative, gain values starting with "0." were always decoded as negative. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Anton Khirnov	5a7e35dd23	Add replaygain side data type and code for parsing replaygain tags.	11 years ago
