Maybe try to encode in a totally different format and container (and back if you desperatly need mp4 - is it playing other mp4 files?). I have made good experiences with adobes media encoder. And to check files "media info" can be quite informative.

Best,

I have a mp4 file (produced by shotcut/ffmpeg) that opens fine with
VLC but causes GEM to stall in a way that I have to kill the process.

In the Terminal from where i start Pd I get this output in red and
bold once the movie file is selected in an open message to pix_movie:

[mpeg4 @ 0x1bb8560] header damaged

many of these lines.. Pd seems to be so busy printing this to the
terminal that it becomes entirely unresponsive.

I tried reencoding the file with ffmpeg, didn't help.

What else can I try?
