I also did not put motion detection examples in this, mainly because I have not satisfied my desire to create a decent API in v4l2 yet for that that.
Next step, I will add sound recording into this.
You can find the example source here.
To compile it, run:
gcc -lavformat bc-record.c -o bc-record
Execute it with a single command line option, the device for a solo6x10 encoder (e.g. /dev/video1). It will record until you hit ^C.
your intelect on this stuff allways impresses me. I havnt a clue what ur talking about.ReplyDelete
I've updated the program. There was one mistake where I was setting the av packet size to the wrong value. It needed to use vb->bytesused.ReplyDelete
Anyone using this, make sure to get the updated copy of the source.
I'm getting this when I try to compile:ReplyDelete
