vdpau libs installed and mesa built with:
./configure --prefix=/usr --enable-gallium-egl --enable-gallium-gbm --enable-gallium-llvm --enable-gbm --enable-gles1 --enable-gles2 --enable-glx-tls --enable-osmesa --enable-texture-float --enable-xa --with-egl-platforms=drm --with-gallium-drivers=r300,r600,svga,swrast,radeonsi,nouveau
It appears mesa no longer automagically detects vdpau. Manually specifying --enable-vdpau builds the needed libs. It would be super if autodetection could be fixed again!
Thanks for reporting, a silly thinko on my behalf is causing this behaviour.
Can you confirm that the patch  fixes the issue on your system ?
Managed to reproduce the problem and confirm that the patch fixes it.
Feel free to reopen if it's failing on your setup.

configure: correctly autodetect xvmc/vdpau/omx
Commit e62b7d38a1d (configure: autodetect video state-trackers
when non swrast driver is present) added a check that caused
the autodetection to be omitted when we have the swrast gallium
driver. Whereas it should have skipped the VL targets when only
swrast was selected.
