Hello forum, I have a mac mini with m2 chip, and I use the Jellyfin App(the .dmg) for mac V10.8.13. I turned on hardware transcoding and selected "Apple VideoToolBox" with all option's checked(HEVC、VP9、H264, etc). However it failed when transcoding HEVC to HEVC format(hevc to h.264 works fine). ffmepg log is as uploaded to the attachment. Please help and check what is happening, thanks in advance!
the ending of the log is as follows：
Stream mapping:
Stream #0:0 -> #0:0 (hevc (native) -> hevc (hevc_videotoolbox))
Stream #0:1 -> #0:1 (truehd (native) -> aac (native))

Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
