Hi!

I’m trying to launch a video from the extension.dav is like this:

gst-launch-1.0 filesrc location=2.dav ! decodebin ! autovideosink

shows this error:

Use Windows high-resolution clock, precision: 1 ms
Setting pipeline to PAUSED ...

opens files with mp4 expansion without problems.

I found information on the web about the format .doc is a proprietary container used mainly by dashcam recorders and
video surveillance systems from Dahua and some other manufacturers. This format differs from standard multimedia
containers (e.g. AVI, MP4), and supports .dav is missing from many popular media players and multimedia frameworks,
including GStreamer.

Please tell me if this is the case and is there a way to run such videos without first converting?

I apologize, I indicated the error incorrectly. It displays such an error:
