Voxl-streamer x264enc with gpu

[Philemon Benner]

Hi,
i'm using voxl-streamer and i'm wondering if it's possible that the x264enc in voxl-streamer can use the apq8096 gpu for acceleration of the encoding. I had a look at gstreamer and x264 subproject has an opencl feature that can be enabled, but i haven't found any examples on x264 with opencl. Also is there a source for docker opencl prebuilt package ? I wanna build it with a different compiler.

@Philemon-Benner x264enc runs on CPU only. But there is omxh264enc on apq8096 that uses Qualcomm HW acceleration.

@Eric-Katzfey Thanks for the answer i will have a look at it.

@Eric-Katzfey is there a way to compile omx core with another compiler ? If so could you refer me to the site where i can build it from source, i haven't found anything yet.
I'm getting the following exec format error:

0:00:10.059630626  4097   0x7f88666070 ERROR                    omx gstomx.c:177:gst_omx_core_acquire: Failed to load module '/usr/lib/libmm-omxcore.so': Error loading shared library /usr/lib/libmm-omxcore.so: Exec format error

I believe the omxcore on APQ8096 is 32-bit. That error implies your host application does not match the omxcore ABI. You might want to try 32-bit compilation

@Chad-Sweet yeah i'm actually using musl toolchain and compiling in 64-Bit. I wanna build omx core with musl from source.

@Philemon-Benner We build this as part of our Yocto system image build. It is 32 bit. We have not tried to build this outside of the Yocto build.
