When try to use segment option of ffmpeg with hevc_qsv ffmpeg can not
split files and continue writing to first created file. Also we tested it
with x265 it works very well:
Command line:
./ffmpeg -v 9 -loglevel 40 -i udp://227.0.1.1:1001 -c:v hevc_qsv
-load_plugin hevc_hw -pix_fmt nv12 -q 20 -profile:v 1 -preset medium
-level:v 51 -b:v 2600k -g 90 -f segment -segment_time 5
-segment_list_type flat -segment_list stream.m3u8 -y -segment_format
mpegts stream%05d.ts
