Rendering and appending an MP4 to an existing file?
With no re-encoding involved, I'd like to create an MP4 file from a JPG, and
append it to an existing file that looks like this:
C:\>ffprobe -i 00000.MTS
ffprobe version 4.2.1 Copyright (c) 2007-2019 the FFmpeg developers
Input #0, mpegts, from '00000.MTS':
