I am trying to play a 20 min short movie.
Transcoding it from 640x352 WMA 170MB video according to
http://wiki.openmoko.org/wiki/Video_Player#Playback_using_480x640_.2F_640x480
Resulting one I tried many sizes, ranging 50-150 in MegaBytes.
But running with mplayer output.avi -sws 0 -nodouble -vo sdl -fs
-framedrop [ -autosync 30 -vf scale -zoom -xy 640 -vf rotate=1 ]
mplayer crashes
Running with glamo mplayer
(http://downloads.tuxfamily.org/3v1deb/openmoko/mplayer-glamo.tar.bz2)
with `-vo glamo' it writes out
Badly interleaved AVI file detected - switching to -ni mode...
And then I can see the video only after seeking, but it is incredibly
slow. Strange, why is it badly interleaved, I have transcoded it with wiki's
mencoder<sourcefile> -o<targetfile.avi> -ofps 13 -vf scale -zoom -xy 640 -af channels=1:0:0:1:0 -oac lavc -ovc lavc -lavcopts acodec=libmp3lame:vcodec=h263p:autoaspect=1:vbitrate=300:abitrate=32
The best performance (~4 fps) I have achieved was with transcoding into
the ~210x100 final video and running opkg installed non-glamo mplayer.
Tried -vo fbdev (-vo sdl does not work), too. Also mplayer crashes were
also occasional.
I am launching a movie from an SD card. Maybe it may slow some things
down, too.
Has anyone gone any better than this, please share.
