[2.2.x] Unable to take snapshot (when using VDPAU)

[Evangelos Foutras]

This feature used to work in VLC 2.1.5 but stopped working in 2.2.0 and remains broken in 2.2.1.

When attempting to take a snapshot, the following error messages are printed to the console:

vdpau_chroma filter error: corrupt VDPAU video surface 0x7fa5e4022f30
core video output error: Failed to convert image for snapshot

I'm using the Mesa 10.5.3 VDPAU driver with a Radeon HD 6870 GPU.

Patch or sponsor welcome.

Same error with a GeForce? GT 545 using NVIDIA VDPAU Driver Shared Library 349.16.

[Nikita Baksalyar]

Can confirm this bug on GT 750M + VLC 2.2.1 (from Fedora 21 packages).

Looks like nobody cares...

I have the same problem after installing the nvidia drivers (GTX 760)

suffering from the same problem. Trying to get to the cc'ed list.

Confirming on Fedora 23

The bug has been fixed in VLC 2.2.4. I do not have privileges to close this bugreport

[Rémi Denis-Courmont]

Pretty sure this is not fixed in 2.2.4.

Not fixed: core filter error: Failed to create video filter2 vdpau_chroma filter error: corrupt VDPAU video surface 0x7f395c0421f0

Arch - vlc-2.2.4-1 with libva-vdpau-driver 0.7.4-2

Replying to jib002:

True, I was not right. The bug has NOT been fixed. I can reproduce the bug with all H264 video files

I am also experiencing this bug with:

• GeForce? GT 750M
• NVIDIA binary driver version 361.42 from nvidia-361
• Ubuntu 16.04 LTS, using GNOME desktop
• VLC media player 2.2.4 Weatherwax

This does not only happen on nvidia cards; my AMD Radeon R7 370 has the same problem.

I had this bug for long. I thought it was only in the packaged (Debian Sid) version, as I noticed it worked when running my own HEAD build. But today I noticed launching the packaged version from terminal also worked. I checked for possible environment differences, but didn't find anything noticeable. Then I saw that quitting all instances and restarting one from terminal also failed. Somehow a second instance is more likely to work, although it's not always the case.

I checked the number of maps of the /dev/nvidia* files, maybe there is a limit for this or something similar, but I didn't get further yet.
