I'm getting really ambitious with my 3-year-old Acer netbook, now that |
| 2 |
open source Poulsbo video support exists. After tweaking the kernel, |
| 3 |
I've got the webcam+mic recording with the command... |
| 4 |
|
| 5 |
ffmpeg -y -f alsa -i plughw:0,0 -f video4linux2 -i /dev/video0 -f avi -vcodec mpeg4 output.avi |
| 6 |
|
| 7 |
mplayer plays the output file fine with the command... |
| 8 |
|
| 9 |
mplayer -vo x11 output.avi |
| 10 |
|
| 11 |
Any suggestions for better options? Would x264 be an improvement? Is |
| 12 |
there a way for the video to be displayed on the screen as it's being |
| 13 |
recorded? Should I be looking at a program other than ffmpeg? BTW, |
| 14 |
here is output from "emerge -pv ffmpeg mplayer" in case anybody has |
| 15 |
ideas for improvements in my USE flags... |
