Closed this issue a year ago · 21 comments

i have ubuntu 20.04 running on jetson nano and try to use it for livestreaming. i would like to make an overlay with an webpage...

so i tried to use gstcefsrc for that i compiled and try to run, but get the following error:

No such element or plugin 'cefsrc'
jetson@nano:~/.sources/gstcefsrc/build/Release$ gst-launch-1.0 cefsrc

That doesn't sound like a cefsrc issue to be honest, have you tried simply googling for the error?

Answer 2 · 2023-02-15T16:16:57.000Z

yes i did, i had this kind of error also with obs. building with a libcef provided by obs (repo) helped there

any hints for doing similar with this project would be great

Answer 3 · 2023-02-15T16:24:17.000Z

You can build with your own CEF version with such a command:

CEF_ROOT=/path/to/chromium/src/out/Release_GN_x64/ cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release ..

I don't think there is much more I can do here, please propose a MR if you have a fix :)

Answer 4 · 2023-02-16T11:38:42.000Z

@MathieuDuponchelle just to have it correct for my build ...

`jetson@nano:~/.sources$ ls obs-build-dependencies/cef_binary_5060_linuxarm64
build cmake CMakeCache.txt CMakeFiles cmake_install.cmake CMakeLists.txt include libcef_dll libcef_dll_wrapper LICENSE.txt Makefile README.txt Release Resources

chrome-sandbox libcef.so libEGL.so libGLESv2.so libvk_swiftshader.so libvulkan.so.1 snapshot_blob.bin v8_context_snapshot.bin vk_swiftshader_icd.json`

CEF_ROOT=~/.sources/obs-build-dependencies/cef_binary_5060_linuxarm64
or a subdir of ~/.sources/obs-build-dependencies/cef_binary_5060_linuxarm64 ??

Answer 5 · 2023-02-16T11:44:17.000Z

with the provied command i get:

Thanks a lot!

Answer 12 · 2023-02-16T16:34:53.000Z

@lblabr can you expand on what worked and what didn't? I can't tell by the images tbh

Answer 13 · 2023-02-16T16:42:26.000Z

obs-browser plugin is used to "stream" a webpage more or less the same what i try to achive with gstreamer and your plugin.

obs-browser:
as you can see the library is not referenced by a link... (how ever this was achieved) build static?

libgstcef.so
libcef.so is referenced by an library (shared??) does not work

but as i sayed, i'm not a dev just have basic knwoledge about how to build... trying a lot sometimes it works some not

Answer 14 · 2023-02-16T17:04:06.000Z

might this help?
https://bitbucket.org/chromiumembedded/java-cef/issues/377/runsh-should-know-its-directory

according to this description:
https://stackoverflow.com/questions/34428037/how-to-interpret-the-output-of-the-ldd-program

for obs-browser the libcef is already in the memory, that's why there is no path in ldd output

how do achive that for cefsrc plugin?

Answer 18 · 2023-02-17T07:46:25.000Z

is it possible to do an overlay to an video with that plugin like they do in:

https://www.youtube.com/watch?v=QNZJYOuVGiE
https://www.youtube.com/watch?v=no7rvUk8GqM (5:45)

?

Answer 19 · 2023-02-17T11:55:28.000Z

yes it is, for overlays you would usually mix things together with a compositor element.

Answer 20 · 2023-02-17T14:57:37.000Z

i'm new with gstreamer, could you pls. share an example?

Answer 21 · 2023-02-17T22:29:02.000Z

@lblabr I advise reading GStreamer's documentation.
