Enabling h264 for cefclient (chromium51_2704_103)

[dverma05]

Hi,

Now open h264 support is available in chrome. Which is the flag needed to enable it at compile time while building chromium.
I have gone through below thread below and applied some of the mentioned flags to my chromium but h264 doesn't work with cefclient.
https://codereview.webrtc.org/1306813009/#ps1010001

At the end it's not clear what all the flags need to be enabled while building chromium. I wanted to enable it for version chromium_51_2704_103.
Any help will be appreciated.

Thanks,
Dileep

What makes you think open h264 is supported in chrome?

Below link is the defect logged for the same and current status is fixed.
https://bugs.chromium.org/p/chromium/is ... ?id=500605

I tested h264 in chrome 53 and it's working.

h264 support is not the same as "open h264" support. Chrome supports h264 via the ffmpeg library which requires a license from MPEG.LA. "open h264" is a product from Cisco that provides h264 playback without requiring a license. Chrome does not support "open h264".

Hi magreenblatt,

You are right. I am OK with the licencing part as encoding is using h264 and decoding is done using ffmpeg and both (h264 & ffmpeg) have their own licencing terms and condition.
That is what I want to achieve in cef3. I tried setting "proprietary_codecs=1 and ffmpeg_branding=Chrome" in cef.gyp file but this didn't work for me.
Can you please let me know where exactly I need to modify these values? Or what all the values or flag do i need to set? and in which file do i need to set these values to achieve this h264 support in cef3?

2704 branch is too old to have the Chromium changes that you linked above. You can set the flags using the GYP_DEFINES environment variable and then building CEF using automate-git.py.

Hi magreenblatt,

Thanks for the valuable info. I will try with the latest chromium available.
