Some progress has been made. With ffmpeg2theora 0.24-2+b1 mencoder 2:1.0~rc4.dfsg1-1 mplayer 2:1.0~rc4.dfsg1-1 in today's unstable bug #590441 does not cause problems. The following test cases produce rotated 320x240 video that actually plays with mplayer on openmoko freerunner [1]: wget http://ftp.acc.umu.se/pub/debian-meetings/2009/debconf9/low/1050_Lightning_talk_Redirecting_require.ogv mencoder -oac pcm -ovc lavc -lavcopts vcodec=ffvhuff -vf scale=320:240,rotate=1 -o 1050_Lightning_talk_Redirecting_require.tmp.avi 1050_Lightning_talk_Redirecting_require.ogv ffmpeg2theora -o 1050_Lightning_talk_Redirecting_require.rot90.ogv 1050_Lightning_talk_Redirecting_require.tmp.avi mplayer 1050_Lightning_talk_Redirecting_require.rot90.ogv youtube-dl http://www.youtube.com/watch?v=Z19zFlPah-o mencoder -oac pcm -ovc lavc -lavcopts vcodec=ffvhuff -vf scale=320:240,rotate=1 -o Z19zFlPah-o.tmp.avi Z19zFlPah-o.flv ffmpeg2theora -o Z19zFlPah-o.rot90.ogv Z19zFlPah-o.tmp.avi mplayer Z19zFlPah-o.rot90.ogv wget http://mirror.cessen.com/blender.org/peach/trailer/trailer_iphone.m4v mencoder -oac pcm -ovc lavc -lavcopts vcodec=ffvhuff -vf scale=320:240,rotate=1 -o trailer_iphone.tmp.avi trailer_iphone.m4v ffmpeg2theora -o trailer_iphone.rot90.ogv trailer_iphone.tmp.avi mplayer trailer_iphone.rot90.ogv This produces huge temporary files but who cares, at least it finally works! ;-) > (Please do not suggest me to get potentially non-free stuff from > http://debian-multimedia.org/ -- I don't want to rely on software that > can not be included in debian if at all possible.) [1] I'm using unreleased libtheora0 1.2.0alpha1+dfsg.1-1 due to its ARM optimizations, I'm expecting it to hit Debian this year. If you are curious you can look at my extremely unofficial repository at deb-src http://lindi.iki.fi/lindi/debian destructive main In addition to that, I'm using a launcher script called "run-mplayer" to do some fine tuning: function cleanup() { sudo om screen glamo-bus-timings 4-4-4 sudo fbset 480x640 sudo om screen resolution normal sudo chvt 7 exit 0 } trap cleanup 1 2 3 15 sudo chvt 2 # disable blanking sudo sh -c "printf '\033[9;0]' > /dev/tty2" # disable cursor blinking sudo sh -c "printf '\033[?17;0;127c' > /dev/tty2" # hide cursor sudo sh -c "printf '\033[?25l' > /dev/tty2" sudo om screen resolution qvga-normal sudo fbset 240x320 sudo om screen glamo-bus-timings 2-4-2 mplayer -framedrop -ac -ffvorbis, -ao alsa -vc -fftheora, -vo fbdev -nocorrect-pts "$@" cleanup -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
