Subject description: problem about video4linux2 library
 

Hi, I have Slacko Puppy version 5.3.1 distro, my computer is old (AMD athlon 1.3Ghz ,500m ram),
I have some problem about terratec Grabby.
I do not have the possibility to use a terratec software (on window),
because it also has Video when encoding the file. It absorbs 100% of my cpu.
I tried with mencoder:
1) first: mplayer -v –tv driver=v4l2:input=0:device=/dev/video0:alsa:adevice=hw.1,0:audiorate=48000:forceaudio:immediatemode=0 tv://
2) second: mencoder tv:// -tv driver=v4l2:width=720:height=576:device=/dev/video0:input=0:alsa:adevice=hw.1,0:audiorate=48000:forceaudio:immediatemode=0 -ovc lavc -oac lavc -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9500:vbitrate=4500:keyint=15:aspect=4/3:acodec=mp2:abitrate=224 -of mpeg -mpegopts format=dvd -o /mnt/sda6/appo1/appo/new/video1.mpg (it absorbs 75% of my cpu)
and it was running good. But this function (mencoder->mplayer2-git10122011.pet) is in i486 and I wants more speed (i686). For this, I used ffmeg, but I have some problem about “video4linux2” library. I lunch: “ffmpeg -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg” and I have the response:
/dev/video0: could not find codec parameters.
I went on internet to see this problem but I saw that the problem is video4linux2 library.
I tried to compile new ffmpeg with “make” function but I saw that the “make” worked
in i486 only. The problem, about ffmpeg, exists in other linux(ubuntu for example).
Do you know How I resolve my problem?
Do you think that it will exist other Slacko Puppy distro without this problem?
I am waiting your response.
Best regards
