How to make a video?

English Open Chat
1

Hi,

I’d like to make a video, with voice, using the integrated webcam and mic
of my laptop. I know they work, but I don’t know if a simple app to create
a video/voice capture exists. I have seen how to make photos, but not video
with voice.

What application would you use?

Perhaps mplayer with some command line incantation?

The purpose is to send it by email to a relative, so perhaps later I’ll
have to recompress with ffmpeg - that part I do know how to do it.

A bit excesive… and for 11.2 it is only available from a home repo.
It could do. :-?

Finally, I have installed “gmerlin” (available in packman). It took some
time to get it running, or for me to understand it, but I can make simple
videos which is the only thing I want for the moment.

Although I have to rerun the .avi videos through ffmpeg, because the
original format can be compressed a lot more.

cheese - although it only records in ogg and you’ll probably have to turn down the webcam resolution to get audio/video sync.

Ah! You could have said it was you… As a rule, I never install from a
home repo unless the owner said so.

For recording videos from a webcam, I find wxcam works ok.

The application I like the best, is guvcview. While designed to work with ‘uvc’ devices/webcams, it also works with any other that is v4l compatible.

The downside of guvcview, is there are NO rpms for it (because it uses proprietary codecs ?? or something else proprietary < not sure > ) and hence one is forced to compile it themselves. I found to compile it I also had to install: libffmpeg-devel, libmp4v2-devel, libxvidcore-devel, libudev-devel, libv4l-devel, portaudio-devel, portaudio-devel, libSDL-devel as dependencies so that guvcview would install.

Once those applications are installed, then on a 64-bit openSUSE-11.3 PC with checkinstall installed, I found the following ‘classic compilation method’ worked nicely in a terminal to build a cheap and dirty home rpm for installation (not to be shared due to shaky nature of the checkinstall rpm):

./configure --prefix=/usr

make

su

checkinstall

and then I installed the rpm that was created in /usr/src/packages/RPMS/x86_64

(because it uses proprietary codecs ?? or something else proprietary < not sure > )

Yep, because it links to libavcodec. I was about to package guvcview some time ago, but when checking all dependencies I noticed this is a no-go under openSUSE rules. However, it is easy to compile and your instructions given above work well with the latest 1.4.3 tarball.
