Thanks for getting back to me Moritz
Have you tried following this hint? Taken from your output log:
> [avi @ 0000000002e8e8c0] H.264 bitstream malformed, no startcode
> found, use the video bitstream filter 'h264_mp4toannexb' to fix it
> ('-bsf:v h264_mp4toannexb' option with ffmpeg)
This seems to have fixed the output. I should probably learn to read the
output a bit more in depth! Here is the console output for the "working"
command from the ffmpeg side.

However, the Raspberry Pi that is looking for the output (listening with
pwomxplayer for a video wall) does not receive anything when using this
command, unless I specifically set the video codec to h264 (-c:v libx264),
this brings new problems with it, creating a lot of "Past duration
0.xxxxxxxx too large" errors or just flatout crashing. I understand if I now
need to go and look for answers from the pwomxplayer side of things, but the
Pi does actually pick up the output with this command, so just need to make
sure that ffmpeg can handle the transcoding I guess!
