Turn on proprietary codecs in Chromium builds

[Balázs Szántó]

Hello!

As far as I know, proprietary codecs (supporting MP3, MP4, ...) are not enabled in Chromium due to license restrictions, however I want to build for myself a Chromium with the proprietary codecs turned on. I use the Chromium Embedded Framework and I set the proprietary_codecs to 1 in the cef.gypi file. Opening the CefClient app and visiting the http://html5test.com/ website told that the browser support these proprietary codecs, but it failed to playback the video files. Going through some forum posts, I copied the Google Chromes libffmpegsumo.dll and the video playback just worked.

My questions is, how to build the libffmpegsumo.dll for my own. Searching the source I see some options, but wasn't able to make it work. Based on the libffmpegsumo.dlls I've built I can say that It wasn't containing the neccesary codes. I've tried some of these flags:

                build_ffmpegsumo

                use_system_ffmpeg

                ffmpeg_branding

                ffmpeg_branding=Chrome

Can somebody point me to the right direction? I'm new to Chromium and CEF, any help is appreciated.

Thanks

Balazs

It should be sufficient to set "proprietary_codecs=1 ffmpeg_branding=Chrome" in your GYP_DEFINES if you're building from our source repository. Make sure you're regenerating the GYP files before building. I'm not sure if CEF has different options for enabling these codecs.

Hi Balazs

I need to compile the Chromium browser with MP4 support? I am trying to follow the instructions below, but not sure which specific source files need to be changed.

I have been able to compile the Chromium once with default values using the Ninja Command, so If I need to now add the MP4 support, which files should I change and what exact changes do I need to make?

How do I regenerate my GYP files?

Regards

VN

Hi 

I am able to successfully compile the latest code from master, but I am finding another challenge, I want to build a specific version of Chromium, the tag 37.0.2062.94. Whenever I switch to this tag, I get the following error while giving the command (c:\workspace\chromium\src>python build\gyp_chromium)

gyp: C:\workspace\chromium\src\third_party\angle\src\build_angle.gyp not found (cwd: C:\workspace\chromium\src)

gyp: C:\workspace\chromium\src\third_party\skia\gyp\record.gypi not found (cwd:C:\workspace\chromium\src) 

while reading includes of C:\workspace\chromium\src\skia\skia_library.gypi 

while reading includes of C:\workspace\chromium\src\skia\skia.gyp

Also the ninja command fails as well.

C:\workspace\chromium\src>ninja -C out/Release chrome

ninja: error: loading 'build.ninja': The system cannot find the file specified.

ninja: Entering directory `out/Release'

Where as in the master, both the commands work successfully, but not in this Tag.

Please help.

Regards

VN

Please make sure to run gclient sync.

Hi Pawel

Thanks for your quick reply. Do you mean i should run gclient sync after switching to the other Tag?

Regards

VN

[Paweł Hajdan, Jr.]

Yes.

Please try "gclient sync --with_branch_heads".

Make sure to read http://www.chromium.org/developers/how-tos/get-the-code/working-with-release-branches

Could you please help me in changing proprietary_codecs to 1? I fetched source code of chromium. but i didnt find cef.gypi file anywhere. 

[Paweł Hajdan, Jr.]

Note this is an old thread.

See Dale's reply about adding proprietary_codecs=1 to GYP_DEFINES env variable.

Also make sure to review other links provided in answers to this thread.

[Naveen Kumar Chittipolu]

Hi Balazs,

I am facing issues with generating chrome build with flags enabling. Can u point me to the right direction?

[Ritesh Rai]

I want to Build CefSharp.Wpf.ChromiumWebBrowser with MP3, MP4 Support.. Let me know if you can help me in this. 

[wax miguel]

[Shuky Chen]

Hi all,

In CEF you can add the following environment variable:

GN_DEFINES="proprietary_codecs=true ffmpeg_branding=Chrome"

This is true for branch 2840 and above
