On my Intel 4770k (bought back in 2014) I can only decode GH5S's 4k 10-bit video at about 30fps with CPU maxing out. This is both when manually using ffmpeg and when using Handbrake. ffmpeg, Handbrake and Vegas 13 are all taking almost realtime to just decode
The system also has NVidia's GTX 1070Ti in it.
I was unable to use Intel's QuickSync (
-hwaccel qsv -c:v h264_qsv before the
-i argument in ffmpeg) or NVidia's NVDEC (
-hwaccel nvdec) to decode the 10-bit h264.
Is there any software solution that can convert the video into something more efficiently usable? Whether 8-bit h264, or 10-bit HEVC, or some other intermediary format that can actually be hardware-decoded by Intel QuickSync or NVENC. Did I overlook any hardware solution? GPU upgrade? CPU upgrade?
I really would prefer not to go back to the good old days of files being decodable at merely realtime.
