Inogeni 4K -> USB3.0 and Jetson TX2

I tried to capture 4k video from Inogeni via gstreamer and it's not working:

Hi, Are you sure that the patch is the right one? It is for GREY not NV12 or I420.gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,width=3840,height On Thu, Feb 1, 2018 at 5:25 PM, Nicolas Dufresne <[hidden email]> wrote:

Oops.
Yes, you figured right. The UVC driver calculates the stride wrong. Be aware that UVC is not zero copy. With Inogeni the memcpy can be visible as 4k 30fps is quite high bandwidth.

What difference between videoparse and rawvideoparse? I have gstreamer 1.8 and similar pipeline don't fix problem: gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,width=3840,height=2160,format=NV12,framerate=30/1 ! videoparse format=23 width=3840 height=2160 ! fakesink 2018-02-02 13:17 GMT+03:00 Nicolas Dufresne <[hidden email]>:

Hi , From the documentation online the videoparse is deprecated and suggest to use rawvideoparse. Best Matteo On Feb 2, 2018 04:48, "Pavel Mikhadzionak" <[hidden email]> wrote:

Hi Nicolas, From my understand this patch was never incorporated. Am I right? This fix aside a problem for GStreamer cause bigger memcpy and so a performance degradation?Do you know if it will be an update about this patch? BestOn Fri, Feb 2, 2018 at 6:01 AM, Matteo Valdina <[hidden email]> wrote:

rawvideoparse is mainly a rewrite. In would not say why it didn't work though.
