Parole fails to play videos with gstreamer1.0-vaapi

[Fiona Klute]

With gstreamer1.0-vaapi installed, parole fails to play videos with codecs supported by my hardware. I usually get an error box with "GStreamer encountered a general stream error.", but sometimes parole just hangs. Videos with other codecs still play as expected.

Accelerated playback works with "gst-launch-1.0 playbin", so I assume the problem is in parole, not in GStreamer.

I use the in-kernel radeon driver.

What codecs does your bug apply to? All of them?

Can you provide a sample video file with which we could try to reproduce this?

[Fiona Klute (fiona-klute)]

Sorry about the long delay! I've reproduced the behavior with h264 (e.g. from Youtube) and mpeg2 videos, while webm (not accelerated) works fine. The behavior is identical on my desktop (submitted the bug report from there, X.Org radeon driver, native vdpau, vaapi emulation) and laptop (X.Org intel driver, native vaapi).

Parole plays the same h264 and mpeg2 videos without problems if gstreamer1.0-vaapi is not installed.

Sadly, there has been no activity in this report for quite some time.

Does this issue still affect you?

[Fiona Klute (fiona-klute)]

I cannot reproduce the bug on Ubuntu 18.04 (parole 1.0.1-0ubuntu1, gstreamer1.0-vaapi 1.14.1-1~ubuntu18.04.1).

A system with native vaapi (intel driver) appears to use it, one with vdpau (radeon driver) does not use acceleration at all despite vdpau-va-driver being installed.

[Theo Linkspfeifer (lastonestanding)]

Thanks for the quick reply.

For the remaining issue, does it work with gst-launch-1.0 properly?

[Fiona Klute (fiona-klute)]

After replacing vdpau-va-driver with mesa-va-drivers it does, and parole does, too. So this bug can be closed. :-)

[Theo Linkspfeifer (lastonestanding)]

Alright. Closing this report then.
