Audio
This SoC has a Hexagon 683 DSP using the WCD9370 audio codec.
Camera
It has the Snapdragon 340 ISP.
Modem
It comes with a Snapdragon X11 LTE Modem.
Video
The device nodes (/dev/video0 and /dev/video1) appears after loading the correct firmware. Some devices may fail at loading firmware due to required minimum firmware version. For example, here is some logs from gta4l:
[ 100.391802] qcom-venus 5a00000.video-codec: non legacy binding [ 100.480622] qcom-venus 5a00000.video-codec: Firmware v6.0.49 < v6.0.55 [ 100.492562] qcom-venus 5a00000.video-codec: probe with driver qcom-venus failed with error -22
Lowering the minimum required firmware version data in the `drivers/media/platform/qcom/venus/core.c` fixes the loading issue. But seems like it's still unable to encode/decode any media.
Trying to use it with ffmpeg results with error message in the below:
[ 947.764552] qcom-venus 5a00000.video-codec: wait for cpu and video core idle fail (-110)
