Trouble Linux uvcvideo video streaming

1,332 Views

HI everyone,

I am reaching different bugs when trying to stream video data using Altera Sockit board. Apparently, it has to do with some issue in the uvc/usbcore drivers where it is unable to transfer frames greater than QVGA. When enabling the uvcvideo trace I get the folowing output in dmesg repeated a hundred times:

uvcvideo: Dropping payload (out of sync).

uvcvideo: Marking buffer as bad (error bit set).

As anyone experienced this before or tried to stream video data using the usb 2.0 OTG controller?

Here is my configuration:

- Altera Sockit

- GSRD last release files

- Linux distribution: Linaro Quantal 13.04 or Angstrom v2014.06

- Kernel 3.14

- Webcam Logitech C905
