Fails to build on Ubuntu versions older than Trusty

[hotice]

libvdpau-va-gl fails to build on Ubuntu versions older than 14.04 Trusty Tahr. Would it be possible to fix this? The previous version was built properly on Ubuntu Precise, Quantal, Raring and Saucy.

Here's the build log for Ubuntu 13.10 Saucy: https://launchpadlibrarian.net/162926990/buildlog_ubuntu-saucy-amd64.libvdpau-va-gl_0.3.1-1~webupd8~saucy_FAILEDTOBUILD.txt.gz

And for ubuntu 12.10 Quantal: https://launchpadlibrarian.net/162927122/buildlog_ubuntu-quantal-amd64.libvdpau-va-gl_0.3.1-1~webupd8~quantal_FAILEDTOBUILD.txt.gz

Newer versions of ffmpeg/libav use AV_PIX_FMT_NV12 while older use PIX_FMT_NV12. I'll try to figure out some workaround to make compilation possible for both versions.

Thank you!

@hotice, can you try to build version from dev branch: https://github.com/i-rinat/libvdpau-va-gl/tree/dev ?

[hotice]

I've tried it and it works!

[i-rinat]

ok, then I'll do couple of pending fixes and make another release in a day or two.

[hotice]

Thank you very much!

v0.3.2 with compilation fix is released now.

On Debian Wheezy, i still get:

@sgdesmet , I've successfully built both v0.3.2 and most recent snapshot in debian wheezy chroot just now. Maybe you are reconfiguring project over previous build? Try to clean build directory and reconfigure again.

Which version of libswscale-dev package do you have on your machine? Is it 6:0.8.10-1?

[sgdesmet]

Hm, it appears I have version 8:1.0.8-dmo1, which came from a third party repository, and is required for xbmc (also provided by that repository)

FFmpeg versioning is a mess. I've found two commits which both essentially the same, they're converting PIXFMT_ macros to AV_PIXFMT_. First changes version from (51, 41, 1) to (51, 42, 0). Second changes version from (51, 73, 102) to (51, 74, 100). But I haven't found commit which changes AV_PIXFMT_ to PIXFMT_ somewhere between (51, 42, 0) and (51, 73, 102). Is it exists? Is there a solid way to check whenever I need compatibility macros or not? I don't know.

You may manually fix src/pixfmt_compat.h if you want to compile it anyway. But as far as I know libvdpau-va-gl have no enough API implemented to use it with XBMC.

[sgdesmet]

Editing that file allowed the build to complete. And as you said, it does not seem to work with XBMC. Thank you anyway though :)
