Hi,
I'm batch transcoding h264 ts streams to h265. Lately, I replaced ffmpeg
3.2.4 with 3.3, and noticed that the average frame rate for transcoding
dropped from about 2.4 to 1.0. For testing purposes, I have switched
back to 3.2.4 for the next file, and the frame rate went up to 3.2.4 again.
Command line:
ffmpeg -analyzeduration 200M -probesize 200M -i "$LOCAL_SOURCE" -vf
yadif=1 -map 0 -c:a copy -c:v libx265 -preset veryslow -x265-params
crf=19 -strict experimental "$LOCAL_TARGET"
I looked through the release notes, but couldn't really find anything
that might be related. The machine is a server, i.e. a CPU without GPU,
and an ASPEED VGA controller.
Any idea for what this could be related to?
Thanks, Chris
