Hi All,
I am writing an audio video player for beagleboard.
I wanted information about the audio and video devices and the help about the ioctl calls.
I have the file utDstream_tennis.c which is source code of “stream_video” in beagleboad, I suppose.
I am able to test video out with my DVI-D supported monitor and its playing the file with “stream_video” command.
I wanted
- More information about the structure “v4l2_format” and want the file “omap24xxvout.h”
- I am not able to understand ret = ioctl(fd, VIDIOC_S_FMT, &fmt);
- What is VIDIOC_S_FMT? I was using LCDFB_YUV420_MODE i.e. _IO(LCDFB_MAGIC, 2) for another device I am working on. Please help me in figuring out what shall be the format here?
- What will be the audio device name? (For video it is /dev/video1 and /dev/video2)
- Can I get the similar source for “aplay”?
As of now I am stuck here.
Please help me or point me to some resources for this work I am doing.
Thanks in advance.
Regards,
Devilal Sharma
