Encode/Decode issues with ProRes 444 Sample

[rexbron]

Sample is available from:  http://files.aehunter.net/DIVISION_SAMPLE.mov

As the sample is only 10MB, it likely consists of only pre-roll (bars and tone and a sync countdown).

Couple of things I noticed (log:  http://pastebin.ca/2120881)

1) Copying the video stream in to a new (shorter) file results in the wrong pix_fmt when probed. yuv422p10le instead of yuv444p10le.

2) Duration of the original file is reported incorrectly. 00:10:39.88 instead of aprox 15 min.

Finally, output from ffmpeg results in garbage image data and severely out of sync audio.

Provided sample is useless.

[rexbron]

Sample was created as per instructions on http://ffmpeg.org/bugreports.html. Instructions are useless. </s>

On a more serious note, I will trim a sample using Quicktime on a Final Cut editing station and upload. Looks like using dd doesn't work for movs.

[compn]

oops, yeah, you cant play incomplete movs. we should update the instructions...

Replying to compn:

Why?
I believe it is pretty obvious that only samples that allow to reproduce the problem make sense. We only request to shorten samples (which is very often very useful) if they are uploaded to our server which is not the case here. And finally, I always explain on this tracker that you have to run tools/qt-faststart before cutting mov files.

I had no idea that tool existed nor its use for debugging. That would be helpful on the bug reporting page. Wouldn't that save you from having to explain that on the tracker?

If the sample need to be uploaded to your ftp, I will happily do so.

Please upload the complete sample (or use tools/qt-faststart to prepare your mov sample for cutting).

Please reopen the ticket if you can provide a sample.
