Package: vlc-nox Version: 0.9.2-1 Hello,
CPU usage for transcoding seems to have more than doubled between 0.8.6
and 0.9.2.
I'm using vlc to transcode and stream v4l content like:
vlc ... v4l://:tuner=0:norm=pal:frequency=18814711 --sout
'#transcode{vcodec=mp1v,acodec=mpga,vb=4000000,ab=256000,venc=ffmpeg{keyint=80,hurry-up,vt=400000}}:std{access=udp,mux=ts,dst=...}'
While a cif size stream used about 10-12% CPU with 0.8.6 it now takes
23-27% with 0.9.2. A 720x576 size stream used about 38-40% CPU with
0.8.6 and takes 95-108% CPU now - both on a Core2Duo E8400.
Same ffmpeg-libs, same kernel. Using v4l2 doesn't help either.
regards
Mario
