Hi,
I have an MXF file (originally generated from Avid Media Composer I
believe) on which ffmpeg fails to correctly read the second audio track.
The file is called test_Stereo.mxf and has two audio channels: on 0:a:0
there are 5s of tone, then 5s silence, then 5s tone, then 5s silence,
while 0:a:1 is reversed (5s of silence then 5s of tone). Outputting
0:a:0 gives a 1kHz tone as expected but 0:a:1 gives a file that is
shorter than expected and sounds garbled (like a fax machine or modem
connecting).
Other programs (eg. Media Composer, QuickTime with the Calibrated{Q} MXF
components, Adobe Premiere) play the original file correctly with a 1kHz
tone on both tracks.
I have just uploaded test_Stereo.mxf (315MB) to ftp://upload.ffmpeg.org
as requested, and include the output of the latest snapshot build below.
Best regards,
-Rolf
PS. Thanks for all your hard work on such a fantastic tool !
