I'm using Chrome on a daily basis or to be exact, latest-builds of Chromium. I recently uninstalled Flash, in order to increase battery life on my MBP and in general rid my laptop of the evil Flash imply.

Now with Chromium's drop of H.264 codec support, enjoying the web is becoming harder and harder. Is there any way to re-enable H.264 support in Chromium?

I know Microsoft (of all players) released such a codec plugin for Chrome recently. Safari isn't really an option although it's sweet.

Out of interest, why isn't Safari an option? – Gerry Nov 23 '11 at 0:43
It lacks the profiles/users feature that was recently introduced in Chromium, that effectively gives me the ability to sandbox sites I use, Facebook for instance. Then there's also certain extensions for Chrome I can't ditch, such as Proxy Switchy. – yusf Nov 23 '11 at 8:01

While announced in January, Chrome hasn't actually dropped support for H264 yet.

Well, since I'm on the Chromium latest builds (can't really go back because of certain new features) the support is certainly dropped. – yusf Nov 23 '11 at 7:55
Then I believe for now, you should consider reinstalling Flash. I'm sure more extensions for supporting H264 will show up when/if it lands in a stable Chrome build. – Gerry Nov 23 '11 at 9:45
@Gerry, nearly 4 years later things haven't changed much: Unfortunately, your prediction ("I'm sure more extensions for supporting H264 will show up") didn't materialize, too bad. – Marcel Stör Jul 15 '15 at 7:20

There doesn't seem to be an easy way to do this. I first thought the following steps would solve the problem, but alas no!

  1. Download and install Google Chrome v40.0.2214.91 from
  2. In Applications, CTRL-click on the Google Chrome icon and select Show Package Contents
  3. Go to /Contents/Versions/40.0.2214.91 which contains Google Chrome Framework.framework
  4. In the Finder, change to list view if you haven't already, so that you can see which files and folders are contained in the above framework
  5. Copy the file from the Libraries folder and paste in the the corresponding folder of your Chromium app
  6. Uninstall Google Chrome
  7. Restart Chromium

I have found that some users have been successful using the Chromium Embedded Framework. Follow this link to head to a post on the forum detailing how to build CEF with support for proprietary codecs (namely H.264 and MP3).

On Mac, prior to building CEF by running the automated script, open the Terminal and set the GPY_DEFINES variable as follows:

export GYP_DEFINES="proprietary_codecs=1 ffmpeg_branding=Chrome"

Instructions explaining how to build the CEF may be found here.

This is useful for people trying to achieve this still. Thank you! I've myself given up on Chrome/Chromium a long time ago. – yusf Mar 23 at 13:50
