[FFmpeg-devel] [PATCH] qsv: Update ffmpeg qsv_errors to recognize GPU hang

[Dmitry Rogozhkin]

GPU hang is one of the most typical errors on Intel GPUs in
case something goes wrong. It's important to recognize it
explicitly for easier bugs triage. Also, this error code
can be used to trigger GPU recovery path in self-written
applications.
