It's just an old armhf "armV7" kind of thing,
but thanks to   it will work for more Ai content.

Installing ffmpeg with encoders and decoders, armhf - armv7:

ffmpeg-rockchip-armhf.zip

 

On rv1126 armbian device:

cd /media/usb/esp32-rv1126-ffmpeg-rockchip
./install-on-target.sh

 

Verify:

/opt/ffmpeg-rockchip/bin/ffmpeg -hide_banner -encoders | grep -Ei 'rkmpp|mpp'
/opt/ffmpeg-rockchip/bin/ffmpeg -hide_banner -decoders | grep -Ei 'rkmpp|mpp'
/opt/ffmpeg-rockchip/bin/ffmpeg -hide_banner -filters  | grep -Ei 'rkrga|rga'

 

 

Please don't trust pre-compiled files. compile yourself:

Use this only if you really want hardware H.264 encode for the go2rtc bridge. A normal upstream FFmpeg build with --enable-rkmpp may expose Rockchip decoders but not the encoder set needed here. For encoder support, use an encoder-capable Rockchip FFmpeg fork such as nyanmisaka/ffmpeg-rockchip, which documents h264_rkmpp, hevc_rkmpp, and mjpeg_rkmpp under encoders.

Build FFmpeg With RKMpp Encoders:

sudo apt update
sudo apt install -y \
  git build-essential pkg-config cmake meson ninja-build \
  yasm nasm libdrm-dev libudev-dev

 

 

The MPP and RGA sources below are hosted on Gitee. If git clone prompts with Username for 'https://gitee.com':, sign in with a Gitee account. That prompt is expected for these URLs and is not an FFmpeg/RKMpp build error.

Build and install Rockchip MPP runtime and headers:

 

mkdir -p ~/src
cd ~/src

if [ -d rkmpp/.git ]; then
  git -C rkmpp pull --ff-only
elif [ -e rkmpp ]; then
  echo "rkmpp exists but is not a git checkout; move it aside or choose a new directory" >&2
  exit 1
else
  git clone -b jellyfin-mpp --depth=1 https://gitee.com/nyanmisaka/mpp.git rkmpp
fi

cd rkmpp
cmake -S . -B build \
  -DCMAKE_BUILD_TYPE=Release \
  -DCMAKE_INSTALL_PREFIX=/usr/local \
  -DBUILD_SHARED_LIBS=ON \
  -DBUILD_TEST=OFF
cmake --build build -j"$(nproc)"
sudo cmake --install build
sudo ldconfig

 

Build and install RGA. The FFmpeg fork can use RGA for hardware color conversion/scaling; this is useful because the ESP32 camera enters as raw YUYV and encoders usually want a YUV420/NV12-style input.

 

cd ~/src

if [ -d rkrga/.git ]; then
  git -C rkrga pull --ff-only
elif [ -e rkrga ]; then
  echo "rkrga exists but is not a git checkout; move it aside or choose a new directory" >&2
  exit 1
else
  git clone -b jellyfin-rga --depth=1 https://gitee.com/nyanmisaka/rga.git rkrga
fi

if [ -d rkrga_build ]; then
  meson setup --reconfigure rkrga_build
else
  meson setup rkrga rkrga_build \
    --prefix=/usr/local \
    --libdir=lib \
    --buildtype=release \
    --default-library=shared \
    -Dcpp_args=-fpermissive \
    -Dlibdrm=false \
    -Dlibrga_demo=false
fi

meson compile -C rkrga_build
sudo meson install -C rkrga_build
sudo ldconfig

 

Build FFmpeg to /opt/ffmpeg-rockchip so it does not overwrite the system FFmpeg:

 

set -e
cd ~/src

if [ -d ffmpeg-rockchip/.git ]; then
  git -C ffmpeg-rockchip pull --ff-only
elif [ -e ffmpeg-rockchip ]; then
  echo "ffmpeg-rockchip exists but is not a git checkout; move it aside or choose a new directory" >&2
  exit 1
else
  git clone --depth=1 https://github.com/nyanmisaka/ffmpeg-rockchip.git ffmpeg-rockchip
fi

cd ffmpeg-rockchip

make distclean >/dev/null 2>&1 || true

# RV1126 is ARMv7-A. Disabling ARMv5TE avoids assembler failures in
# libavcodec/arm/mlpdsp_armv5te.S on some armhf toolchains.
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/local/lib/arm-linux-gnueabihf/pkgconfig:/usr/lib/arm-linux-gnueabihf/pkgconfig \
./configure \
  --prefix=/opt/ffmpeg-rockchip \
  --enable-gpl \
  --enable-version3 \
  --enable-libdrm \
  --enable-rkmpp \
  --enable-rkrga \
  --disable-armv5te \
  --enable-shared \
  --disable-static \
  --disable-doc \
  --disable-debug

make -j"$(nproc)"
sudo make install

echo /opt/ffmpeg-rockchip/lib | sudo tee /etc/ld.so.conf.d/ffmpeg-rockchip.conf
sudo ldconfig

 

This only disables FFmpeg's CPU hand-written assembly. It does not disable the Rockchip MPP encoder or RGA support, and it is acceptable for this camera path because the input is only 320x240 @ 3 fps.

Verify that FFmpeg was built with actual encoders:

 

/opt/ffmpeg-rockchip/bin/ffmpeg -hide_banner -encoders | grep -Ei 'rkmpp|mpp'
/opt/ffmpeg-rockchip/bin/ffmpeg -hide_banner -decoders | grep -Ei 'rkmpp|mpp'
/opt/ffmpeg-rockchip/bin/ffmpeg -hide_banner -filters  | grep -Ei 'rkrga|rga'

 

Expected Result:
 

/opt/ffmpeg-rockchip/bin/ffmpeg -hide_banner -encoders | grep -Ei 'rkmpp|mpp'
/opt/ffmpeg-rockchip/bin/ffmpeg -hide_banner -decoders | grep -Ei 'rkmpp|mpp'
/opt/ffmpeg-rockchip/bin/ffmpeg -hide_banner -filters  | grep -Ei 'rkrga|rga'
