Hi!
Summary of the bug:
When doing x265 encoding, the stats file (-vstats_file; see: stats.txt)
doesn't contain information about frame types and "q"-s. Instead of
values, there are question marks for frame types, and zeroes for "q"-s.
For example:
frame= 181 q= 0.0 f_size= 1627 s_size= 68kB time= 7.458 br=
312.4kbits/s avg_br= 74.9kbits/s type= ?
Also, "q"-s are not set in the output as well (see: output.log and
report.log).
How to reproduce:
{{{
ffmpeg.exe -r 24 -i "1080-png\sintel_trailer_2k_%04d.png" -c:v libx265
-x265-params "level=3.0:crf=28:keyint=48:min-keyint=48:scenecut=0" -r 24
-pix_fmt yuv420p -filter:v "scale='trunc(oh*a/2)*2:360'" -vstats_file
"stats.txt" "360p-hevc.mp4"
}}}
