I use a 5M camera and try to bring up with FULL resolution(2592x1944) by Gstreamer. This is my pipeline with nvv4l2camerasrc: gst-launch-1.0 nvv4l2camerasrc bufapi-version=TRUE device=/dev/video0 ! \ 'video/x-raw(memory:NVMM),format=UYVY,width=2592,height=1944' ! nvvideoconvert ! 'video/x-raw(memo…

hello jerry.liu21023, that’s due to VI’s alignment, the buffer width should be alignment to 64. you may modify the buffer size as 2688x1944 for capturing full-size resolution (2592x1944), and cropping redundant pixels by 2D engine.

hello jerry.liu21023, may I know what’s the sensor format dumps. $ v4l2-ctl -d /dev/video0 --list-formats-ext

Hi Jerry $ v4l2-ctl -d /dev/video0 --list-formats-ext ioctl: VIDIOC_ENUM_FMT Index : 0 Type : Video Capture Pixel Format: 'UYVY' Name : UYVY 4:2:2 Size: Discrete 1280x720 Interval: Discrete 0.033s (30.000 fp…

how about running gst pipeline with nvv4l2camerasrc as below. $ gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! 'video/x-raw(memory:NVMM), format=(string)UYVY, width=(int)2592, height=(int)1944, framerate=(fraction)30/1, interlace-mode=progressive' ! nvvidconv ! nv3dsink -e

No, it cannot work. $ gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! 'video/x-raw(memory:NVMM), format=(string)UYVY, width=(int)2592, height=(int)1944, framerate=(fraction)30/1, interlace-mode=progressive' ! nvvidconv ! nv3dsink -e nvbuf_utils: Could not get EGL display connection Setting pipe…

hello jerry.liu21023, may I know which Jetpack release version you’re working with. also, please share the failures from the kernel side. thanks

Hi Jerry, We use JetPack 4.6.1 These are kernel messages after I run your pipeline. [ 2935.891654] tevi-ap1302 30-003d: sensor_set_mode() , {3}, fmt_width=2592, fmt_height=1944 [ 2935.891666] tevi-ap1302 30-003d: sensor_start_streaming() [ 2935.895498] [RCE] vi5_hwinit: firmware CL2018101701 prot…

hello jerry.liu21023, it shows VI engine to discard frames, the error reported channel encountered an uncorrectable error and it must to be reset. it might also due to frame got corrupted, those illegal data packet dropped by CSIMUX. is it correct frame-rate reported by list-formats-ext? please …

Hi Jerry, The vi error only occurred the first time opening camera and it can stream after resetting the capture channel. is it correct frame-rate reported by list-formats-ext ? Yes, the resolution is correct but the real framerate varies depending on the influence of our camera’s setting. The…

hello jerry.liu21023, according to v4l standard ioctl to access the buffers, it’s reported 14-fps. there’re some potential issue for frame-rate not reaching to 30, for example, it may due to the pixel clock settings you’ve given is too low. or, some exposure settings to limit the frame-rate capabi…

Hi Jerry, I think it is not clock or exposure issues because I can use v4l2src to get the correct image from the streaming as I mention. Correct Image by using v4l2src: gst-launch-1.0 v4l2src device=/dev/video0 ! \ 'video/x-raw, format=(string)UYVY, width=(int)2592, height=(int)1944, framerate=(f…
