It seems the feature is broken again in 24.5.0esr-1~deb7u1. I have all the packages suggested above(*) and some more installed, but Youtube reports no H.264 support. It worked before the last update.
lib264-123 and libx264-142 are installed as well, but I'm almost certain they don't help. libx264 is only used for encoding, not decoding. Note: I'm using jessie with security updates pulled in from wheezy-updates. gstreamer0.10-ffmpeg comes from wheezy as well, as jessie only carries gstreamer1.0 and libav. Did the dependencies change?
