I committed your code to the Audacity SVN with your name in Signed-off-by, because I failed to find a git-am equivalent to preserve the committer and date. Thanks for your work. While committing, I made some small indentation adjustments. Audacity uses 3 spaces for indentation and some of your changes used 4 spaces. I merged your debug fprintf removal into the respective commit. I also committed my libav 9 support patch. > > 2) I can't export audio as mp4.

My description was imprecise and incorrectly (m4a instead of mp4). I was talking about File -> Export Audio... -> "M4A (AAC) Files (FFmpeg)". When selecting this format, the exported file has 0 bytes content. Selecting "Custom FFmpeg Export" and then "mp4" format and "aac" codec, the result will be the same (empty exported file). The same applies for the wav format with pcm_s16le codec. -- Benjamin Drung Debian & Ubuntu Developer _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
