You can find the toolchains, Dockerfiles and install scripts I used on my GitHub: This is required because the userland libraries are in a nonstandard location, ld will not search in /opt/vc/lib by default. rpath-link is used to find shared libraries required by other shared libraries at link time, -rpath is used to find the libraries at run time. Wl passes a list of comma separared arguments to the linker. The -I flags specify the include paths, and the -L flags returned by pkg-config -libs-only-L are the library paths. This is done by setting the right environment variables here. Note that pkg-config is configured for cross-compilation as well, it looks in the Raspberry Pi sysroot, not in the build machine root. extra-ldflags="$(pkg-config -libs-only-L mmal) \ extra-cflags="$(pkg-config -cflags mmal) \ enable-omx -enable-omx-rpi -enable-mmal -enable-neon \ enable-libvpx -enable-libx264 -enable-libxvid \ This is what I used to cross-compile ffmpeg for AArxh64. You have to provide some extra flags to point ffmpeg to the right header and library locations, both at compile time and at run time. Maybe can someone point me in the right direction? Meta-openembedded master: commit daa50331352c1f75da3a8ef6458ae3ddf94ef863īTW, by using V4L2-M2M, I'm getting green shadows on the resulting video. How do I get missing library libopenmaxil.so and everything I need for hwaccel? Is it possible to access omx hardware acceleration on RPI4-64?ġ.Download latest Poky distro, meta-openembedded, meta-raspberrypi I have tried different combinations of virtual providers and graphics settings but without success. I have tried reverting to userland by DISABLE_VC4GRAPHICS = "1", it produced bcm_host.so, but not libopenmaxil.so. If I will provide manually omx headers, then it will compile but FFmpeg encoding will fail due to missing libraries: bcm_host.so and libopenmaxil.so I'm using FFmpeg and AFAIK hwaccel can be reached by using OpenMAX or V4L2-M2M.Īfter '-enable-omx' and 'enable-omx-rpi' for FFmpeg, build fails with error: 'OMX_Core.h not found'.
I'm trying to get to work hardware acceleration on my Raspberry pi 4-64.
