2012-09-03 Grandparents like to see lots of picture ... 8 years ago
Grandparents like to see lots of pictures of their grandson. And some things (like walking) are easier to see in video. So I made some video with my phone and found it is saved in .3gp format. Something Nokia-specific and I want all grandparents (using windows and ubuntu linux) have full access to the video. So, mencoder to the rescue. The audio codec isn't recognized at all, but the video can be played with mplayer, and converted to other formats. So I convert it to mp4, with options:$ mencoder Video000.3gp -o video000.mp4 -oac lavc -ovc lavc -lavcopts vcodec=mpeg4:autoaspect=1 -fps 12The frames per second option is needed to get things right. The resulting video of this test conversion is this video of usb sticks with leds being filled with data in parallel, result of copying data to lots of usb sticks at work in 2009.
