I have planned to develop a Personal Video Recorder (PVR) application which works using DirectFB. From the DirectFB examples I can able to grab video streams from /dev/video0.
"Xawtv" Tv Viewer works under X11 uses v4l (Video4Linux) API to talk to the bttv based TV tuner card using bttv driver.
One of our member Mr.Ville Syrj�l� suggested me earlier to use TvTime and redirect the TvTime output to Matrox card's Tv out. But TvTime fails to work in textmode. It requires grahics, X11. So I planned to develop a PVR application which works without "X", using DirectFB.
I want to scan for channels and fix the same. I have splitted the modules as follows. Let me know whether my understanding is correct and will I reach the destination if the following modules are completed successfully.
1) Scanning and fixing the channels using v4linux API.
2) Grab video streams and develop alpha blended user interface using DirectFB API.
3) Add audio support.
4) Add lirc support.
My doubt is,
1) Is it possible to add audio support to DirectFB programs? (For ex: df_window, df_video example programs)
2) Can we code program which use V4l Linux API's and DirectFB API's ?
I will use v4l API only to scan for channels and fixing the same. Then I will use DirectFB API to grab video stream and add audio support.
Is my understanding is clear ? Will these module divisions work out ?
Thanks in advance.
With Regards, S.Suriya Mohan.
