Comment (by msiders):
Hi,
And to demonstrate that the bug isn't related to CUDA, but to "hwdownload"
I ported the example to QSV:
{{{
% ffmpeg -stream_loop -1 -y \
-loglevel error \
-hwaccel qsv \
-c:v h264_qsv \
-i "https://samples.ffmpeg.org/MPEG2/mpegts-klv/Day%20Flight.mpg" \
-filter_complex
"hwdownload,format=nv12,scale=400:300,hwupload=extra_hw_frames=32,hwdownload,format=nv12,fps=25,scale=800:600"
\
-c:v h264 \
-f mpegts out.ts
}}}
The output shows the exact same bug!
