Hello,
My first post to this list, and I must say so far today I've found Gmerlin
to be quick useful, especially the visible timecode function in the Gmerlin
Transcode.
This specific post however is regarding a failure to transcode an XDCAM HD
file containing 16-bit PCM audio.
When I attempt to transcode, the error I receive with Gmerlin Transcode is:
avcodec_open failed for audio
When I query this file using FFmpeg, it returns the following data:

To me it seems like my file contains pretty straight forward 4 channels of
16-bit PCM audio, which FFmpeg should handle (I've chosen FFmpeg audio/video
encoder in the "Encoder" preferences).
Any thoughts much appreciated.
Cheers
Phill
