Could not write header for output file #0

I've been successfully using your excellent scripts on an Intel based QNAP to effectively leverage ffmpeg to re-container MKV to MP4, transcode an AAC track for iOS support and place it first, then copy DTS audio track if it exists. At least I think that's what I've done. :)

This has been working well until today. This appears to be the specific cause of the ffmpeg failure.

Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

Transcoder section of autoProcessMedia.cfg is as follows:

[Transcoder]
    # getsubs. enable to download subtitles.
    getSubs = 0

    extractSubs = 0
    # externalSubDir. set the directory where subs should be saved (if not the same directory as the video)
    externalSubDir = ""
