Video Zoom does nothing on vlc after upgrade to Xenial

[Colin Law]

Since upgrading to Xenial, Video > Zoom in vlc appears to do absolutely nothing. Whatever value I select the image stays the same size and zoom. Tried with avi and mp4 files.

Intel i915 graphics, if that is relevant.

If you disable VDPAU entirely, by turning off hardware decoding and switching the video output module to XCB, does zoom work? You can't test hardware zooming without the libvdpau-va-gl1 package installed and either Automatic or VDPAU selected as the decoder and output module.

[Colin Law (colin-law)]

I have switched the output to XCB. By hardware decoding do you mean Accelerated video output(Overlay)? I have disabled that but zoom still does nothing. Also I still see the libvdpau message.

[Brandon Snider (brandonsnider)]

Input/Codecs => Hardware-accelerated decoding

Automatic is the default, which just means the list in the order it appears in the drop-box -- VDPAU at the top.

[Colin Law (colin-law)]

OK, disabling Hardware-accelerated decoding has got rid of the libvdpau message, but zoom still does nothing.

Status changed to 'Confirmed' because the bug affects multiple users.

[Jan Groenewald (jan-aims)]

I get this on debian stretch with vlc 2.2.4 and libvdpau-va-gl1 0.3.6-1+b1, disabling hardware acceleration and setting video output to xcb fixes autoscale.

[Jan Groenewald (jan-aims)]

apt-get purge libvdpau-va-gl1 fixes this for me so I don't need to make above changes.

[Colin Law (colin-law)]

@Jan Groenwald can you describe exactly what you mean by 'autoscale'? What are you doing to show that it is working? I ask because I am still seeing the problem, so if I select Video > Size > Double or Quarter it does not change the image size. This is with XCB o/p and acceleration disabled.

apt-get purge libvdpau-va-gl1 fixed this problem for me

[Colin Law (colin-law)]

@Roman is that on Ubuntu, if so which version? libvdpau-va-gl1 is not installed on my Ubuntu 16.04 system.

Re #8:
Disabling hardware acceleration fixes it for me as well:
vlc -> Tools -> Preferences -> Video -> Accelerated video output (Overlay): turn off.
