Thanks for the port

I'm using rc1 with no problem playing local files ( not much testing )

though when I browse with GMPlauncher to a shared file
it crashes upon loading the file

in fact whatever I use to attempt to play a shared file, the app will crash.

Has anyone been able to play a shared file?

thanks

Me again. I'm able to record a few seconds of less-than-stellar video from the built-in webcam with the following command:

Code:

mencoder -cache 256 tv:// -ovc lavc -lavcopts vcodec=wmv2:vbitrate=256 -of lavf -tv driver=v4l2:width=160:height=120 -vf scale=160:120 -fps 15 -nosound -o test.wmv

Those settings produce the longest, least ugly file. The problem is that when I start mencoder, it records a few seconds and then gets an error. The recording continues, but the output file is unusable after the error occured. I keep getting this error every second or three. Here's the error (the number in the square brackets is always different):

Code:

v4l2: ioctl dequeue buffer failed: Input/output error, idx = 000 [319.0]

MP4 seems to die much more quickly than WMV.

Any ideas?

This works for recording fairly decent, uncompressed video from the internal cam. Save it to a big flash card because it eats 140 MB per MINUTE. You will have to compress this after recording....

Code:

mencoder -cache 512 tv:// -ovc copy -tv driver=v4l2:width=320:height=240:noaudio -fps 15 -oac copy -o /media/mmc1/video/test.avi

I have yet to get the audio working. I have no idea how to access the mic via ALSA; what is the hardware ID?

If I use ":alsa=1" in the -tv options, I get:

Error opening audio: Device or resource busy

If I use ":alsa=1:adevice=hw.0,0" I get:

ALSA lib pcm.c:2144snd_pcm_open_noupdate) Unknown PCM hw:0,0
Error opening audio: No such file or directory

Hi,

just something i've ran into. Playing a "high quality" video from youtube has some problems.

that movie was a hi-res mp4, audio was fine, video was freezed, when seeking the first frame was the correct one, after the first frame video got freezed, cpu 100%

(seek works even when freezing occurs).

Not sure you can do something ... but i hope you can

Cheers
Mihai

Bundyo, I'd love an mencoder with lamemp3 audio encoding support. Right now, any audio recorded on the tablet is uncompressed PCM, and it would be nice to have an on-tablet mp3 compressor. Thanks!
