vlc-9999 +vdpau -libav / ffmpeg +vdpau won't build

[thunderrd]

When building in Gentoo vlc live ebuild with vdpau enabled together with ffmpeg live ebuild, vlc fails with this output:

Code: Select all

checking for XCB_RANDR... yes checking for XCB_KEYSYMS... yes checking for VDPAU... yes configure: error: VDPAU requires FFmpeg libavcodec < 57.10 or libav. !!! Please attach the following file when seeking support: !!! /var/tmp/portage/media-video/vlc-9999/work/vlc-9999/config.log * ERROR: media-video/vlc-9999::gentoo failed (configure phase): * econf failed

I see in the ebuild that:

Code: Select all

# Temporarily block non-live FFMPEG versions as they break vdpau, 9999 works; # thus we'll have to wait for a new release there. RDEPEND="${RDEPEND} vdpau? ( >=x11-libs/libvdpau-0.6:0 !libav? ( >=media-video/ffmpeg-2.2:0= ) libav? ( >=media-video/libav-10:0= ) )

To me this indicates that when building vlc with vdpau enabled, and libav disabled, one needs to have the live ffmpeg version with the same flags. Am I interpreting this incorrectly?

Interestingly, ffmpeg-2.8.5 allows vlc-9999 to build. This is contrary to what I read in the ebuild, I think.

Hey, thanks for the answer, Remi, it's easier to understand for me now after reading that ML message. I'll stay with =ffmpeg-2.8.x for now.

Realistically, do you expect the ffmpeg devs to resolve this eventually? I've had a libav-free system for quite a while now, and don't look forward to returning to it.

I don't expect it, but I don't know.
