Hello, I see that support for vaapi is not in ffmpeg and vlc. I took ffmpeg-0.8.5-2.fc16.src.rpm and vlc-1.1.12-1.fc16.src.rpm from rpmfusion and recompiled them on my F16 system. I'm far from an rpmbuild expert and all conditional statements inside them, so I tried putting in spec files - $ diff ffmpeg.spec ffmpeg.spec.orig 123,124c123 < --disable-stripping \\\ < --enable-vaapi --- and - $ diff vlc.spec vlc.spec.orig 324d323 < --enable-libva \ 343c342 < ##%{!?_without_mozilla:--enable-mozilla} \ --- 560,564c559,563 < #%{!?_without_mozilla: < #%files -n mozilla-vlc < #%defattr(-,root,root,-) < #%{_libdir}/mozilla/plugins/libvlcplugin.so < #} --- (basically I didn't accomplish how to compensate a problem with firefox headers that prevented compilation, so I just disabled firefox plugins at all for my initial purpose...) Then yum reinstall : sudo yum reinstall ffmpeg-0.8.5-2.fc16.x86_64.rpm ffmpeg-libs-0.8.5-2.fc16.x86_64.rpm sudo yum reinstall vlc-core-1.1.12-1.fc16.x86_64.rpm /vlc-1.1.12-1.fc16.x86_64.rpm It seems all is ok on my system that is an Asus laptop U36sd with intel corei7 and sandy bridge 00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) (prog-if 00 [VGA controller]) 01:00.0 VGA compatible controller [0300]: nVidia Corporation Device [10de:1050] (rev ff) (prog-if ff) $ vainfo libva: libva version 0.32.0 libva: va_getDriverName() returns 0 libva: Trying to open /usr/lib64/dri/i965_drv_video.so libva: va_openDriver() returns 0 vainfo: VA API version: 0.32 vainfo: Driver version: i965 Driver 0.1 vainfo: Supported profile and entrypoints VAProfileMPEG2Simple : VAEntrypointVLD VAProfileMPEG2Main : VAEntrypointVLD VAProfileH264Baseline : VAEntrypointVLD VAProfileH264Baseline : VAEntrypointEncSlice VAProfileH264Main : VAEntrypointVLD VAProfileH264Main : VAEntrypointEncSlice VAProfileH264High : VAEntrypointVLD VAProfileH264High : VAEntrypointEncSlice VAProfileVC1Simple : VAEntrypointVLD VAProfileVC1Main : VAEntrypointVLD VAProfileVC1Advanced : VAEntrypointVLD and playing Avengers trailer from http://www.h264info.com/clips.html I get good results from fluidity point of view... ot the same form cpu usage... perhaps... $ cvlc The\ Avengers\ -\ Trailer.mp4 VLC media player 1.1.12 The Luggage (revision exported) Blocked: call to unsetenv("DBUS_ACTIVATION_ADDRESS") Blocked: call to unsetenv("DBUS_ACTIVATION_BUS_TYPE") [0x252afe0] dummy interface: using the dummy interface module... libva: libva version 0.32.0 libva: va_getDriverName() returns 0 libva: Trying to open /usr/lib64/dri/i965_drv_video.so libva: va_openDriver() returns 0 [0x7f82a8c02e70] avcodec decoder: Using VA API version 0.32 for hardware decoding. my cpu is Intel(R) Core(TM) i7-2620M CPU @ 2.70GHz with dual core and HT during play [g.cecchi@ope46 ~]$ vmstat 3 procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu----- r b swpd free buff cache si so bi bo in cs us sy id wa st 3 0 1644 129136 102032 4069252 0 0 113 98 1215 1516 16 4 80 0 0 5 0 1644 135452 102036 4062712 0 0 683 27 8823 11317 34 3 63 0 0 1 0 1644 136080 102036 4063920 0 0 427 0 8755 11254 34 3 63 0 0 3 0 1644 130880 102040 4069600 0 0 1579 9 8616 11205 33 3 64 0 0 2 0 1640 129020 102040 4071528 11 0 608 5 8917 11533 34 3 63 0 0 2 0 1640 125920 102044 4074112 0 0 853 17 8622 11253 33 3 64 0 0 top - 18:15:28 up 1:46, 7 users, load average: 0.79, 0.40, 0.35 Tasks: 172 total, 3 running, 169 sleeping, 0 stopped, 0 zombie Cpu0 : 78.1%us, 1.3%sy, 0.0%ni, 19.9%id, 0.0%wa, 0.7%hi, 0.0%si, 0.0%st Cpu1 : 11.3%us, 2.3%sy, 0.0%ni, 85.7%id, 0.3%wa, 0.3%hi, 0.0%si, 0.0%st Cpu2 : 30.0%us, 2.3%sy, 0.0%ni, 67.3%id, 0.0%wa, 0.3%hi, 0.0%si, 0.0%st Cpu3 : 15.3%us, 3.0%sy, 0.0%ni, 81.1%id, 0.0%wa, 0.7%hi, 0.0%si, 0.0%st Mem: 8147792k total, 7975236k used, 172556k free, 100252k buffers Swap: 10485756k total, 2640k used, 10483116k free, 4016804k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 9098 g.cecchi 20 0 1189m 118m 87m S 94.1 1.5 1:00.38 vlc Any feedback on my results and on possible default inclusion of vaapi in ffmpeg and vlc?
