[FFmpeg-user] Recovery of broken Dohiker 'trailcam' videos

Good day all,
A friend loaned me a Dohiker trail camera. It was set up
to trigger a 20 second recording when movement is
detected.
It produced AVI files after I set it up overnight. However,
while some of the videos play both video and audio,
others have no video, only audio when played with
VLC or ffplay. Additionally, ffmpeg reports 'conversion
failed' (full output appended) when trying to transcode.
Are these files likely to be recoverable? If so, can I use ffmpeg
for that? I tried uploading to Google Drive / YouTube as
they have been able to 'rescue' broken files in the past;
however, neither worked.
Interestingly, a few files from both the start and end of
the session play okay. This presumably correlates with when it
got light again, or similar.
I am happy to provide working and nonworking video samples,
and any output that I may have omitted.
Thanks in advance,
Rob
PS I am using version 'n4.4' provided by my distro in the
first instance - last updated 2021-05-06 - but I am happy
to attempt compiling from git
