(And while at it, gst-vaapi 0.6.0 -> 0.6.1.) * gst-editing-services grew additional build time dependencies, flex and perl. * gst-libav switched from libav to ffmpeg as "libav" provider, see http://gstreamer.freedesktop.org/releases/1.6/. Without using ffmpeg, one may hit issues such as this (which I initially did): (gst-plugin-scanner:19751): GStreamer-WARNING **: Failed to load plugin '/nix/store/0wgpq2yx9wrkp2mh4rn1c7zbiq2bqa2l-gst-libav-1.6.1/lib/gstreamer-1.0/libgstlibav.so': /nix/store/0wgpq2yx9wrkp2mh4rn1c7zbiq2bqa2l-gst-libav-1.6.1/lib/gstreamer-1.0/libgstlibav.so: undefined symbol: av_frame_get_sample_rate
