ffprobe exits with "Unsupported codec with id..." error

Description

Summary of the bug:

Our application handles hundreds of video files produced by the same specific hardware set and uses ffprobe to read the metadata of the files.

We use the the Canon XA25 camera to shoot videos which are then transported to the Teradek cube 155 that streams the video file via NFS to our local server where the ffprobe operation happens.

Out of ~100 files we had 5 failures with ffprobe with the following error message:

Unsupported codec with id 0 for input stream 2

The full output before the this error message is:

As you can see I use the latest stable ffprobe 2.4.3, on osx yosemite.

How to reproduce

Use the attached video file with ffprobe (if attachment fails use this link to download file: http://than.pol.as/Yq8K):

The download link does not work.

comment:2 Changed 3 years ago by thanpolas

Yes, indeed for some reason it failed to upload on both ends (attachment + my service)

Here is the new clip url: http://than.pol.as/Ypxb and you can download it using this specific url: http://than.pol.as/Ypxb/download/Reveal-PCST-120414-122114.mp4, updating the ticket...

Please test current FFmpeg git head. There is nothing unstable about it.

Is the problem you are reporting only reproducible with ffprobe or also with ffmpeg? Only report issues for ffprobe if they are not reproducible with ffmpeg.
I don't see an error message in your original report and I therefore don't understand this ticket currently...

comment:4 Changed 3 years ago by thanpolas

ffmpeg will properly process the file and the output is readable by ffprobe. However we cannot afford (the cpu / time) to process all the incoming clips so this is not a solution.

I have presented a specific error message and the complete output of ffprobe in my original report.

I have also produced a reliable way to reproduce the issue with the file you can download from here.

If this is the wrong Bug Tracking engine for ffprobe then please show me to the right one.

It is the right bug tracker (you just have to explain that it works with ffmpeg when you report an issue with ffprobe), I just haven't understand yet what your issue is: Afaict no error is shown in your original report and the output if ffprobe looks fine: What is wrong about it?

comment:6 follow-up: Changed 3 years ago by thanpolas

You need to be more diligent when reading reports. As I am stating in my original post, the error generated reads:

Unsupported codec with id 0 for input stream 2

The process exits with Code 1 which in turn is propagated in the underlying controlling method in our application and thus the whole operation fails.

We can find multiple workarounds to this issue like downgrading the ffmpeg error to just a warning vs stopping our whole OP but I thought it would be a good idea to bring this to your attention.

  • Component changed from undetermined to ffprobe

Replying to thanpolas:

You need to be more diligent when reading reports. As I am stating in my original post, the error generated reads:

Unsupported codec with id 0 for input stream 2

Why did you cut this from your console output?

The process exits with Code 1 which in turn is propagated in the underlying controlling method in our application and thus the whole operation fails.

Did you explain this in your original report?

Did you already test if the issue you see is reproducible with current FFmpeg git head?
