Stream video data to host PC(windows) through USB
I am using DM368 Soc,able to capture video and encode in mpeg2 as per my requirement. But I am not able to understood how to
stream video data to host PC(windows) through USB.everyone mansion use UVC class API but i am not able to find out uvc class based application.
Please provide your guidelines in this.
You need to use uvc gadget driver at drivers/usb/gadget/uvc_video.c etc. and there is no standard application to use this. You can search for the same or write your own application for the same.

Thanks for reply.
I am using linux-220.127.116.11.where no such file uvc_video.c available in drivers/usb/gadget dir.but I am able to find this c file in drivers/media/video/uvc dir.
I have also find some video streaming application as with attachment.let me know these application are suitable for my requirement otherwise need to write own application from scratch.
Here some quires:
1. DVSDK 4.2 - Encode demo application used ioctl(hCapture->fd, VIDIOC_STREAMON, &type) for what purpose ? means only for recording video from
input (composite ,s-video) in temp buffer or else like stream over usb ?
uvc_video.c is added in v2.6.34 and you wil have to either port back that to your kernel or move to latest kernel. I don;t know about your question on ioctl, may be someone else would respond on this.
I am using the UVC gadet driver for streaming video data to the PC. In addition to that, I also need to notify the PC about some status changes at the device side once in a while. Does the uvc_video.c driver in 2.6.34 support this feature? If yes could you help in mentioning how this is handled.
