you could export LIBVA_TRACE=filenames to get libva trace

[danielzgtg]

LIBVA_TRACE=filenames to get libva trace

Nothing happened. I tried both export LIBVA_TRACE=/tmp/libva_trace.log ; sunshine and export LIBVA_TRACE=filenames ; sunshine . There was no file containing "libva" in /tmp or the current directory.
