Video file name / url in output file

[BrunoLansacSBD]

Hi,
First of all, thanks for the tool. It works great!

When I annotate video files, and for that purpose I create an annotation task per video, I cannot seem to find any reference to the original video name / path / url inside the task itself. Moreover, inside the output XML file generated after annotating, there are no references to that information at all. The only thing I can find is the url of the corresponding task, but I don't think I can extract from that url the information I'm looking for (i.e. the name of the video).

The only workaround I can think of is naming the annotation task after the video itself, and do the same for the xml file. However, I don't really like that solution. The ideal solution for me would be to have video file name inside the xml file.

Am I missing something? Please point me in the right direction.

Thank you very much

Hi @BrunoLansacSBD ,

I believe it can be useful information. Could you please prepare a merge request for the feature?

Hi @nmanovic ,

Could you please give me a hint on where in the code should I implement that? I'm sure it is by far easier for you to point me in the right direction than me going through all the code.

Thanks

Hi @BrunoLansacSBD ,

I believe you need to modify 'dump' function here: https://github.com/opencv/cvat/blob/develop/cvat/apps/engine/annotation.py#L1636

Also it seems that we don't have name of video file into DB. There are two solutions:

• Add it to DB (preferable) - https://github.com/opencv/cvat/blob/develop/cvat/apps/engine/task.py#L626
• Find it in upload directory - https://github.com/opencv/cvat/blob/develop/cvat/apps/engine/task.py#L513

Still cannot find video filename at dumped xml annotations:

@azhavoro , could you please slightly improve your patch and implement the feature?

[nmanovic]

It is already fixed in develop branch.

@nmanovic is this solved? I can't see the name of the file anywhere in a "CVAT for video 1.1" export.
Are people using CVAT with out this feature? I don't understand how that is possible?
