I need to transcode 4K30 HEVC files to lower resolution (1080p) based on your wiki. But it seems there is double free and aborts.

Is this stupid?

There is so many errors before 'double free'. Try delete /dev/ion.

[jjm2473]

Did you check /dev/dri exists?

If you are using RGA3 (for example RK3588), there is a bug https://github.com/JeffyCN/mirrors/issues/11
