Required gstreamer plugin 'libav' not found (Follow up to [FDH2/UxPlay] UxPlay 1.62 (Discussion #172)) #173

Thanks for your reply and a big sorry for posting in the wrong channel.

I tried uxplay and got this error:

UxPlay 1.62: An Open-Source AirPlay mirroring and audio-streaming server. Required gstreamer plugin 'libav' not found Missing plugin is contained in '[GStreamer 1.x]-libav'

next I searched for libav which is installed under /usr/lib/gstreamer-1.0/libgstlibav.so by package gst-libav 1.20.5-1

I read that vaapi might be a problem - so I deleted it and recompiled uxplay, but no success eigther.

regards, Marcus

Its working for me on latest Manjaro. (are you on X86_64 or arm (R Pi?))

does gst-inspect-1.0 libav show it is available for gstreamer?

Thanks for the kind support - I got it up and running :-) I am using the latest Manjaro (X86_64) gst-inspect-1.0 libav showed it was unavailable for gstreamer, even though pacman -Qi gst-libav showed the identical version as yours.

A simple reinstall didn't worked. I had to remove almost all gst-XX plugins - reboot (sick nightmares return) - then reinstall all needed gst-xx plugins and finally gst-inspect-1.0 libav could find something. Then recompiled uxplay and it worked smoothly again.

regards, Marcus

Sorry to bother you - I have a different problem now. While typing, the IPad went to sleep and the connection to uxplay was lost. When I run uxplay now, it connects to the IPad, but then I get the following error: uxplay -nc -vs ximagesink

I am on KDE Plasma and X : update : using uxplay -vs vaapisink works.

p.s.: uxplay -d last lines are

This below is something added in uxplay-1.62. It was supposed to stop needless searches for the X11 window if default (autovideosink) selected something non-X11

I will need to see if this new code has broken something. @IInatas

please test with -vs xvimagesink -vs glimagesink -vs ximagesink <-----this is what failed, I think -vs gtksink -vs autovideosink

and report which of these work and dont work for you Thanks

My success with the various parameters:

I don't know what changed in the last two hours? I tried uxplay -vs ximagesink and uxplay several times last time and they always failed. This time I tried the other options first, maybe that changed something, because before the IPad went to sleep it worked fine with uxplay.

regards, Marcus

p.s.

fduncanh commented 1 year ago

sounds good.

Is this issue ready for closing?

IInatas commented 1 year ago

For me this issue is solved - thank you for your kind support.

P.P.S: The problem that uxplay does not start has reappeared:

UxPlay 1.62: An Open-Source AirPlay mirroring and audio-streaming server. Required gstreamer plugin 'libav' not found Missing plugin is contained in '[GStreamer 1.x]-libav' stopping

It is clearly a problem with gstreamer in combination with uxplay, but I could not find the cause. ... but, a workaround on nvidia developer that works. rm -rf ~/.cache/gstreamer-1.0/ Maybe it's a problem with nvidia lib's, but I have no way to check.

HTH, Marcus
