Please test current FFmpeg git head and provide the command line you tested together with the complete, uncut console output and an input sample to make this a valid ticket.

Can you play the input file with any media player? For me,
VLC, Windows Media Player and FFplay all fail.

As far as I can see, the sample file only consists of the
ftyp, a wide and the mdat box, which, I think, does not
make it a valid mp4 file, although I am not sure about that.

Hello sorry for the delayed response. I have compressend and sent the file as it is limited to 2mb(This is followed from ffmpeg official website). I am sharing the original video via google drive (​https://drive.google.com/file/d/1D9h2QLzHj9BBBUoENQHl3SKgp3dx1Ej1/view?usp=sharing)

[Carl Eugen Hoyos]

Could you elaborate a little on this ticket? How was the file created?

Patch sent.

[Tomas Härdin]

This file is a polyglot, created by "IPV MXF Multiplexer". In other words it is both an MP4 file and an MXF file. One workaround here is to add -f mp4 to the ffmpeg command line. I'm not sure whether the file is supposed to be decoded as MXF, it is glitchy with -f mxf. Waiting for user feedback.
