Unable to compile

[i-rinat]

VDP_DECODER_PROFILE_H264_CONSTRAINED_BASELINE was added only in the recent version of libvdpau, that's why it's absent on 0.7. I've added compatibility macros' in 3fc29a5. Could you check whenever source from master branch compiles now?

There were also other changes in code, so it would be nice if you check whenever it also works, not only compiles.

It fails again.

There were another change in libvdpau: VdpPictureInfo type was changed from void * to void, which made C++ compiler unhappy.

I see no sane way to make compatibility wrappers for that change, so I've changed code to use bundled VDPAU headers instead (4f53876 and a8cd82f). Should be better now.

Now it compiles with any problem, but I don't think it works:

[i-rinat]

Are you sure you are using recent version? I think I removed all occurrences of string "vdpDeviceCreateX11" from the code. There is no even a function named that anymore.

It could be there are another version of libvdpau-va-gl built, and libvdpau uses it. There is a list of paths that are checked, and first found library is loaded.

Try to set environment variable VDPAU_DRIVER_PATH to the path where newly built libvdpau_va_gl.so.1 resides.

[i-rinat]

I've just tried to test on Ubuntu 12.04, and found that libvdpau it has, doesn't know about VDPAU_DRIVER_PATH variable yet. You need either to place libvdpau_va_gl.so to some library path, or add its directory to the library search path. You could do the latter by export LD_LIBRARY_PATH=$PWD. That will add current directory.

Still no avail :/

[i-rinat]

$ LD_LIBRARY_PATH=$PWD

That only sets variable for current shell session, but not for child processes. Try to use

$ export LD_LIBRARY_PATH=$PWD

[extinctpotato]

Nope, still the same.
I think it might be some sort of a problem with i915 driver though.

[i-rinat]

Do you have another compiled libvdpau_va_gl.so anywhere in the filesystem?

[i-rinat]

I think it might be some sort of a problem with i915 driver though.

It could be. Function vdpDeviceCreateX11() tries to compile couple of GPU shaders that used for colorspace conversion. As far as I know, Mesa falls back to software emulation of shaders if hardware have no appropriate support. But it could be that particular version used is returning error instead.

As the initially reported bug was solved, I'm going to close this issue.

As for "Acer Travelmate 240/250" machine, I did a quick search and found that's it has a Pentium 4 processor. It doesn't have a hardware video decoder, which was only introduced in Core family since about 2010.

Without VA-API support, libvdpau-va-gl will be slower and more CPU time consuming than using Xv output in video players like MPlayer or mpv, since it does data format conversion in a non-optimal way.
