MXF output has some too short audio streams when transcoding from mp2

[wim_arbor]

Summary of the bug:

I am trying to convert a TS file with MPEG2 video and mp2 audio to XDCAM MXF with the same MPEG2 video, but 8 tracks AES3 audio. Audio track 1 is ok, but the other audio tracks are 1 frame too short.

How to reproduce:
xdcam8mp2-2s.ts has been uploaded to upload.ffmpeg.org/incoming
I will attach ffmpeg-20151007-104736.log to this ticket, see also below:

This part of the verbose output on the console seems to show the problem;

The message [mxf @ 0x3264a80] missing frames might also be relevant, but I don't get this on other input files.

The problem can also be shown using ffprobe

Although the duration of all streams is 0.88, audio stream 1 has 22 frames, the other audio streams have 21 frames. FFprobe shows 20 frames for stream 0 (video), but I believe this should be 22.

Using MXFDump from ​https://github.com/Limecraft/ebu-libmxf confirms the output has 22 video frames, the first audio stream has also 22 frames, all other audio streams have 21 frames. I'll also attach the MXFDump output xdcam8mp2-2s.mxf.txt

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

MXFDump output of xdcam8mp2-2s.mxf

[wim_arbor]

ffmpeg -report output

[wim_arbor]

I will create a related ticket later today where the same ffmpeg command with a different input file causes a Segmentation fault.

[wim_arbor]

created #4914 where a 1-second version of the same file, causes a segmentation fault when executing the same command as in this ticket.

[Carl Eugen Hoyos]

Please upload your sample again.

[wim_arbor]

I have reuploaded xdcam8mp2-2s.ts to upload.ffmpeg.org
