Title:
Can't play video X.org on Ubuntu 21.04
Status in libvdpau package in Ubuntu:
Confirmed
Bug description:
I have upgraded my Lenovo Z50-75 (AMD A10-7300 with integrated Radeon
R6 GPU) from Ubuntu 20.10 to Ubuntu 21.04 and can no longer play
videos with mplayer (nor vlc) when using X.org (that I need to use
Cinnamon but I've tried without Cinnamon and seems to be X.org
related).
Description: Ubuntu 21.04
Release: 21.04
mplayer:
Installed: 2:1.4+ds1-1
vlc:
Installed: 3.0.12-3
If I login using Ubuntu on X.org, I'm unable to play videos with
mplayer nor vlc.
I downloaded sample video from https://sample-
videos.com/video123/mp4/720/big_buck_bunny_720p_1mb.mp4
The video plays ok if seen in Firefox.
If I try to use mplayer, the window opens, the sound plays but no
video. On the console lots of errors like:
[vdpau] Error when calling vdp_video_surface_put_bits_y_cb_cr: No backend
implementation could be loaded.
A: 0.2 V: 0.0 A-V: 0.250 ct: 0.000 0/ 0 ??% ??% ??,?% 0 0
If I try to use vlc, similar thing happens. The sound plays but no
video. On the console lots of errors like:
[h264 @ 0x7f48ecce3640] hardware accelerator failed to decode picture
On Ubuntu 20.10 it was working ok.
