Hello
if you use TDA2x or TDA2Ex, it supported H264 Enc/Dec. Vision SDK has examples to showcase MJPEG/H264 Encode + Decode

Hi Shiju Sivasankaran ,
I want information related to webcam driver, where and how can i add H264 support. What you are referring is more toward application/firmware side.

I do not think TI SW  stack support WebCam drivers, please check Gstreamer or something similar.

From Linux side you can plug IVA H264 codec by using TI IPUMM (codec Engine) SW packages

Hi Shiju Sivasankaran,

I'm using glsdk_7_04_00_03 satble kernel as per vision sdk document,

check kernel/omap/drivers/usb/gadget/legacy/webcam.c

As you can see in legacy their is support of webcam, i have even loaded webcam driver, just i haven't yet tested. 

static const struct uvc_descriptor_header * const uvc_hs_streaming_cls[] = {
         (const struct uvc_descriptor_header *) &uvc_input_header,
         (const struct uvc_descriptor_header *) &uvc_format_yuv,
         (const struct uvc_descriptor_header *) &uvc_frame_yuv_360p,
         (const struct uvc_descriptor_header *) &uvc_frame_yuv_720p,
         (const struct uvc_descriptor_header *) &uvc_format_mjpg,
         (const struct uvc_descriptor_header *) &uvc_frame_mjpg_360p,
         (const struct uvc_descriptor_header *) &uvc_frame_mjpg_720p,
         (const struct uvc_descriptor_header *) &uvc_color_matching,
         NULL,
 };

If you check here support for yuv and mjpg support is their.

I'm looking to add H264 support?

Ganesh

Ravi, Sriram, Can you please respond?

As per UVC specification for H.264 data is streamed over USB, the format descriptor type is MPEG2-TS. The pay load carries H246 data.
What is your exact requirement with respect to H.264. Whether you want to encode to H.264 before sending over USB ?

Hi Ravi B,

Whether you want to encode to H.264 before sending over USB ?

Yes.
