Error reading MOV file

[FishB8]

I have a mov file recorded on an AJA KiPro. I've never had a problem with the files from this device until now.

The contents should contain "Apple ProRes 422(LT)" for the video stream, and "pcm_s24le" for the audio streams, plus a "tmcd" timecode.

This particular file will open and play with quicktime without audio, so something in one or both of the audio tracks is messed up. Oddly enough VLC for MacOS manages to open and play with audio.

With ffmpeg I get the following:

[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f426c0093e0] Invalid sample_count=-1744855732
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f426c0093e0] error reading header

This is using ffmpeg-3.1.5. I can build and test with current head if that would seem to make any difference.

The file is rather large (368G) so let me know how I can submit a chunk that is just large enough to provide enough info to work with

Without a sample, fixing a possible issue will not be possible. Our upload server does not work currently, please use a filehoster of your choice.

[FishB8]

Is there any way to provide a sample without loading the entire file? Is the header alone enough to figure out what the issue is. I don't know of many filehosters that can deal with a 368G file.

[FishB8]

See if this is enough.

Replying to FishB8:

Is there any way to provide a sample without loading the entire file? Is the header alone enough to figure out what the issue is. I don't know of many filehosters that can deal with a 368G file.

Why don't you upload the first 100MB?

[FishB8]

Can do.

[Carl Eugen Hoyos]

Use tools/qt-faststart to move the moov atom of the original (complete) file in front, then verify that the new (large) file plays fine with vlc and upload the first 100MB of the new file.

[FishB8]

Ah, thanks. I had assumed qt-faststart would have bailed the same way ffmpeg / ffprobe did. Good to know.

Confirmed it does play (with audio) in VLC.
