Aye Mr. Azik ;-)

@mrazik i dont have the original workflow from first page which was share through wetransfer but i can quickly rebuild the functionality for you.
Again, the original workflow here was using A/V Decoder to filter on the video but in the end, the original unmodified audio should be used.

Looking at the history of this thread, we can simplify the original workflow because it would "unpack video and audio", this is not needed; we can just work with the original source file's audio in the final wrapping step.

Workflow:
A/V decode->Video Filter->Encode->rewrap using original Audio
emcodem_use_original_audio_with_avdecoder.json

Note that the final delivery path is set in the commandline proc. Also, i use mkv extension there hardcoded because the matroska format is virtually able to work with any audio track config and codec.

Hi @emcodem :),

thanks for the workflow, but does not help for my issue....

Point is that after A/V Media node I'm generating new H.264 file, but this file has than wrong audio dicrete tracks (all 16 went to single one with 16 channels).
Without using of A/V Media node in the transcoded file there is correct 16 discrete tracks.

I'm not sure what I'm doing wrong :(

Can you please advice?

Many thanks!!!
