AM3352: GStreamer V4L2 error

Hello,

1. Could you please share which PSDK you are using?

2. 

I tried to modify the V4L2 with Gstreamer stuffs.

Please provide more information on what you have modified.

3. If you run the following command "gst-inspect-1.0 v4l2src", are you able to see the plugin information?

Regards,
Krunal

Hi Kurnal:

Thanks for replying.

#1. I'm using AM5 6.0.1.8 :Linux.

#2. Sorry for letting you mis-understand.

      I didn't modify the V4L2 code yet, I want to try to use the Iphone being the USB cam and let the Iphone Cam output the streaming showing on the AM5 EVM.

#3. Here is the output after inspect:

gst-inspect-1.0 v4l2src

No such element or plugin 'v4l2src'

Hi Kurnal:

I have new progress now.

While plugging my iphone to the AM5 EVM, and I use the command below, it will show the error log.

How to resolve it?

Cmd:

gst-launch-1.0 -v souphttpsrc location=http://172.20.10.1:80 do-timestamp=true ! jpegdec ! autovideosink

Hi Rio,

Please confirm if you are using AM5728 EVM or AM335x EVM (post title says AM335x)?

Hi  Kurnal:

Sorry for the typo, it's AM335 EVM..

THanks, I already solved the issue using FFMpeg instead of using GST.
