RV1103 support #90

Closed 14Og closed 1 month ago

14Og commented 1 month ago

Hi there! I'm using luckfox pico mini b board, which runs on rv1103 SoC, that is not listed in rockchip mpp support list, but i have mpp headers and library in my buildroot images. So i have question: is there any chance to cross-compile your ffmpeg fork for this type of boards? I've tried to use default ffmpeg version in their buildroot sdk, but it doesn't have rkmpp support, and their h264_v4l2m2m encoder doesn't work too. Assuming that there is mpp support for this SoC, how can i build this version of ffmpeg for target board on my host PC? FFmpeg has a great explanation on how to cross compile their library, but rockchip mpp has no documentation on how to cross-compile this library, and, as i can see, it is required to compile it on my host machine in order to build your ffmpeg version. Thanks in advance!

but rockchip mpp has no documentation on how to cross-compile this library,

Here is a code snippet showing how to compile mpp for armhf/arm64 on amd64. but i don't know what c library rv1103 uses, if it's not glibc you have to use the cross compiler provided by the vendor.

Yep, thank you! Will try to build it for my platform
