This worked for me in the end…
It seems like when I used a lower ofps the video would play faster than the audio causing sync problems… but this worked fine on a 30 min video i tested…

mencoder in.mpg -o out.avi -oac mp3lame -lameopts mode=2:cbr:br=96:vol=0 -ovc lavc -lavco
pts vcodec=mpeg4:vbitrate=100:vhq:vpass=1:vmax_b_frames=0 -ffourcc XVID -vf scal
e=160:128 -ofps 15;

looks like mencoder doesn’t do b-frames properly. ffmpeg might work though. Then use mencoder to recode the output of ffmpeg once the b-frames are gone.

I used Chris’ x5enc() script. The resulting video plays great with mplayer, but the video plays too fast on the iaudio x5. The audio plays at the correct speed, so there is a sync problem. Google says that I need to remove the B-frames from the avi to make this work correctly. I did RTFM on mencoder but couldn’t figure out how to get this working. Anyone know how to remove the B-frames from the video, so that it plays in sync on the iaudio? Cheers,
Raj.

That’s weird. I’ve tried encoding it on linux with slightly different options. They work as well but it runs choppy. Here’s what I tried.

mencoder movie.mov -ofps 15 -vop scale=160:120 -ovc xvid -oac mp3lame -xvidencopts bitrate=800 -lameopts cbr:br=128 -o movie.avi

I noticed I experienced problems playing movies when I used lavc for audio encoding. After switching to -oac mp3lame -lameopts cbr:br=128 it works nicely. Also I thought about running mplayer -vo null -nosound -frames 1 and check the output for the video size so I can switch between scale=160:-3 and scale=-3:108

Encoding movies for the X5L using free software…

Hiya,

today I wanted to try the video playback feature of my X5L. With some help from huw, I worked out this mencoder line:
mencoder input -o output.avi -ovc lavc -oac lavc -lavcopts acodec=mp3:abitrate=128:vbitrate=128 -vf scale=160:-3 -ofps 13&nb…

Hi, thanks for the mencoder line. I’ve been playing around a little with mencoder before but had something wrong.

You can additionally lower the video bitrate to save quite some space (and probable CPU power on the device), because with this resolution you don’t need high bitrates. By default, I got something like 350kbps for the video and I don’t see any difference to the 150 I use now and they save nearly 50% of space. Plus I used “-3″ as the second scale parameter so the aspect ratio will not be modified by mencoder. Here’s my new shell function:

x5enc() {
# Encode video to run on X5/X5L player
# usage: x5enc SOURCE TARGET
mencoder $1 -o $2 -ovc lavc -oac lavc \
-lavcopts acodec=mp3:abitrate=128:vbitrate=128 \
-vf scale=160:-3 -ofps 13
}

Maybe using -o xvid can get even better results, but It’s more CPU intensive while encoding.

cheers chris

neil,
you probably need to install lame

Available codecs:
copy – frame copy, without re-encoding (useful for AC3)
pcm – uncompressed PCM audio
mp3lame – cbr/abr/vbr MP3 using libmp3lame
lavc – FFmpeg audio encoder (MP2, AC3, …)
