Hello everybody.
I've got a problem. On my web-server stores 250 Gb of videos encoded with codec VP7.
Now I must:
- Re-encode videos with xvid.
- Take screenshots in GIF format from 10 frames.
- Place watermark from transperent GIF
Initially I wanna use FFMPEG, but when I install it I get error while encoding because he doesn't understand input codec. And also I know that getting screenshots is very slowly in FFMPEG (for screenshot at 30 minute it takes 52 seconds). So I decide to try Mplayer. But he is not support watermarks at all.
AFAIR VP7 is part of Intel Indeo codecs which versions above 3.0 doesn't supported in any opensource project.
Then I find rather interesting lines at http://www.mplayerhq.hu/design7/info.html
Then when I install mplayer and try to use it I've got another error:# Intel Indeo3 (3.1, 3.2)
# Intel Indeo 4.1 and 5.0 (using x86 DLL or XAnim codecs)
What's wrong with it? (((root@Ubuntu-804-hardy-LTS-64-minimal:/www/pages/klipz.ru/1# mencoder test.avi -o test2.avi -of lavf -ovc xvid
