It’s tricky enough getting hardware video encode to work on Linux with “this is just an Intel IGP, the exact same thing as every other Intel IGP”. Decode can even be tricky at times. I am very pessimistic about getting video editing software working on a system as far off the beaten path as a Snapdragon.

If you stick with more mainline hardware, you have fallback positions like “use linux Davinci” or “dual boot Windows and use one of the gazillion tools there”, or “MacOS has its own cavalcade of media tools”.
