Kernel 4.1.x support ? #7

Open ranaya123 opened 7 years ago

Hi I have a custom capture card based around tw6865. I use following kernel tree and driver : https://github.com/boundarydevices/linux-imx6/tree/boundary-imx_4.1.15_2.0.0_ga/drivers/media/pci/tw686x

The issue I have is, most of the time the capturing rate is pretty slow and who kernel freezes after few frames. And the chip only seems to work with v4l2src, not imxv4l2videosrc (this sounds problematic) !

When running the pipeline, I also see the error message : v4l2bufferpool gstv4l2bufferpool.c:748:gst_v4l2_buffer_pool_start:v4l2src0:pool:src Uncertain or not enough buffers, enabling copy threshold


  1. does your driver works with kernel 4.1.x ?
  2. If yes, do we still need DMA USRPTR patch ?
  3. To get imxv4l2videosrc to work, do we need a patch for gstreamer plugins as well ?

Thanks in Advance Anuradha
