FFAStrans 1.4.0.x Audio to MXF Encoding issue

artjuice · Post by **artjuice** » Mon Apr 22, 2024 8:44 pm

Hello

Found new issue for a workflow: Monitoring (folder with mp3, wav audio) -> Encode (to XDCAM-HD) -> Deliver (to folder, ftp)
Result file, MXF had a doubled duration. If audio was 60sec, MXF will be 120sec (audio track + audio track again).

If needed can attach workflow and samples.

So, the file is indeed twice as long as 2 min 38 s twice is 5 min 16 s.
The audio however isn't going faster or slower, it stays in sync with the clip from the beginning to the end

Once it reaches 2 minutes 38 seconds (i.e the end of the clip), it starts again from the very beginning.

From the command line I can see:

However indexing the file and going through Avisynth helps, in fact adding the A/V Decoder set to "No Decode" (i.e leverage on ffms2) before the XDCAM encoding node fixes the issue:

Checking the logs, we can see that FFAudioSource() was called to index the .wav file
