Playback of .mov file fails

Postby ygoe » 17 Apr 2020 18:13

I have an old video file here that I could play with an unknown video player many years ago. It's a short sequence that I'd like to convert into something that's compatible with today. VLC can't play it and I have no idea what format it is. I've uploaded it here ([url]https://ygoe.de/s/RPfZM5c1SvYm56C8[/url]). ffmpeg does convert the file into mp4 or mkv, but the result has no video stream in it anymore. What are my options now?

Has anybody got an idea how I could read and convert that old video file?

Strange file indeed! It crashes MPV after 2 or 3 seconds, MPC-HC displays a black screen and stops the playback after something like 5 seconds.
FFplay can play it but it complains about a duplicated MOOV atom:

There are several streams in the file (MediaInfo): JPEG, RLE, MPEG-4 Visual, Timed Text, ... VLC 2.0.8 can play the video, but it is played in a separate "VLC (Direct3D output)" window. There are 3 separate windows. Another "VLC (Direct3D output)" window is black and main interface with controllers is just black, too. It is possible to remux the file in MKVToolNix and just to select the MPEG-4p2 stream there.

Great, thank you all! MKVToolNix has converted that stream into a file that I can view again.
