I am working with Cef build cef_binary_3.3497.1840.gcd24143_windows32.
when I run the cefclient,the GPU process keeps crashing showing:

Code: Select all

[1022/165344.478:ERROR:browser_gpu_channel_host_factory.cc(132)] Failed to launch GPU process.
[1022/165344.480:ERROR:gpu_process_transport_factory.cc(1017)] Lost UI shared context.

What could be the cause of this failure?
Are there more logs somewhere from chromium or cef that could provide a little more info for debugging?

What windows version are you using? Are you running in a VM?

See https://chromium.googlesource.com/chrom ... ed_code.md and https://www.chromium.org/developers/how ... on-windows for GPU debugging tips. To get symbolized stack traces you can download symbols from the same place you got the binary distribution.

Usual causes are:

- compatibility manifest missing:

- missing GL libs
- on linux export BROWSER=google-chrome[-stable]

I run the cefclient in a PC ,using windows 10.I get Embedded Framework from http://opensource.spotify.com/cefbuilds ... s32_builds, and the code from https://gitlab.com/xiliumhq/chromiumemb ... /tree/3497

I try to add a manifest file, and GL libs: libEGL，libGLESv2，still not working.the GPU process keeps crashing showing:

Lol.

Where you add manifest? All applications (cefclient & cefglue demo already has embedded manifests).

What it you added libEGL? You should use all files and libraries from binary package. Read readmes, they describe which files needed.

First, you should get worked cefclient. Try debug build, it may hasmore meaningful errors.

Run from console with --enable-logging --v=1 to get verbose messages.
