Comment 3 for bug 991758

I'm running chromium-browser Version 41.0.2272.76 Ubuntu 14.04 (64-bit) and installed the chromium-codecs-ffmpeg and chromium-codecs-ffmpeg-extra but I still can't play mp4/H.264 videos in the browser. I get a black window with a play button, an empty progress bar, "0:00" and a disabled audio button, but no video frame or playback.

The same video plays in Firefox.

VLC reports Stream 0 is Video, H264 - MPEG AVC (part 10) (avc1), decoded format Planar 4:2:0 YUV; Stream 1 is audio MPEG AAC Audio (mp4a1)

I believe I've installed these correctly:
