[LUG.ro] mplayer con XVideo Motion Compensation

Sat, 8 Sep 2007 14:21:14 -0300

Buenas, el tema es el siguiente. Tengo una placa nvidia FX5500 con los
drivers propietarios, y leí por allí que el XVideo Motion Compensation
hace que al reproducir un video labure la placa y no el CPU. Por lo
tanto, quiero tratar de activarlo.
Lo primero que hice es poner en el archivo /etc/X11/XvMCConfig la
siguiente línea:
libXvMCNVIDIA_dynamic.so.1

cuando trato de ejecutar un video con xvmc, me tira este error:

$ mplayer -vo xvmc Journeyman.S01E01.Pilot.DVDSCR.XviD-SAiNTS.avi

que el XvMC está levantando bien, traté con lo que dice ahí de agregar
-vf spp,scale y tira exactamente lo mismo. Por ahí encontré que había
que agregar -vc ffmpeg12mc, en ese caso tira esto:

y sólo escucho el audio... sin video. Noten en las líneas

que dice que hubo algún problema con el codec, entonces, como el video
que estaba tratando de reproducir es un xvid, lo tiré con -vc xvid,
pero hace lo mismo.

Probé con un MPEG2, y funca (horriblemente, intercala frames negros en
el medio, además, si giro el cubo en mi compiz-fusion, la peli queda
arriba en todo momento y no en la cara del cubo).
Esta fue la salida:

----------------------------

Lo de que quede por arriba del cubo, me suena a que el mplayer está
usando el xvmc, por lo tanto lo maneja la placa de video y el cubo no
¿habrá alguna forma de que el compiz use también XvMC?

Ideas?

Salu2

PD: Como verán, no tengo la más puta idea sobre video
