videoPlayerExample not working/freezing on Linux gst 1.22

[sphaero]

Printing out errors:

[warning] ofGstUtils: setSpeed(): unable to change speed
[ error ] ofGstUtils: setSpeed(): couldn't query position

The app doesn't want to exit but prints:

[warning] ofGstUtils: didn't received EOS in 5s, closing pipeline anyway

When I start the app without a mouseover the video plays and loops but as soon as the mouse is involved (setting speed) the video freezes. Often freezes at frame 201 of 218 or at a negative frame.

I think somethings were changed in gstreamer as I think I'm seeing similar issues is processing. Haven't been able to pinpoint it yet.

I'm on debian trixie which is now using gstreamer 1.22.6

Thanks for reporting this!
Yeah, there were a lot of fixes for 0.12 due to gstreamer changes that broke the video player.

I've added this to our 0.12.1 issue #7588 - I'd be interested if it happens with a different video file.

did you happen to install the codec in scripts/linux/debian/install_codecs.sh

[sphaero]

From my own direct gstreamer test it does differ with video files (codecs?). I'm testing around with newer gstreamer versions so I didn't test it thoroughly. I also noticed problems with processing with newer gstreamer. You don't happen to have a list of what changes in gstreamer affect the videoplayer?

Btw I don't think I used the install_codecs script. But gstreamer was at 1.22.6 at the time. I also tested my own build from the gstreamer source but it had the same problems.

@sphaero did you manage to discover if there were any working codecs which allowed seeking?

[sphaero]

No I can't recall. I haven't been testing it since then either

[ofTheo]

Can you test with the latest nightly build?
This seems fixed on Linux Mint for me.

I do get:
[ error ] ofGstUtils: setSpeed(): couldn't query position

but the speed changes work
