Hi I use the code to save raw video as a file gst-launch-1.0 -e v4l2src device=/dev/video0 \ ! "video/x-raw, format=(string)UYVY, width=(int)2592, height=(int)1944,framerate=(fraction)28/1" \ ! filesink location=video-raw-file.UYVY and play back: gst-launch-1.0 filesrc location=v…

Hi, For SDIO speed, please take a look at JetsonNano_DataSheet_DS09366001v1.1.pdf 884.80 KB For video quality, there are encoder properties you can adjust and check. You may refer to [image] H264 vs H265 Jetson Nano Hi, For compar…

filesink is a cpu only plugin and cannot use NVVM memory as outputted by nvv4vl2camerasrc. You would have to insert nvvideoconvert in between for copying from NVMM to standard memory: gst-launch-1.0 -e nvv4l2camerasrc device=/dev/video0 ! 'video/x-raw(memory:NVMM), format=UYVY, width=2592, height=…

Sorry for previous command. It would work with nvvidconv, but you would have to specify standard memory as its output: gst-launch-1.0 -e nvv4l2camerasrc device=/dev/video0 ! 'video/x-raw(memory:NVMM), format=UYVY, width=2592, height=1944,framerate=28/1' ! nvvidconv ! video/x-raw, format=UYVY ! fil…

Thanks for kind reply. The code can save the video as a file. The recorded time is 29.4946 S, but play back is only 2.9211 S. I don’t know what’s wrong with it, frame lost or something else?

Hi, Saving raw UYVY frames take heavy load and may not be able to reach source rate. Also timestamp information is not included. Suggest you record the frames into mp4 or mkv.

Hi DaneLLL, Thank you very much for your kind suggestion. I have noticed that to save raw UYVY frames, the write speed requirement for Micro SD card is very high. Would you please let me know what is the max write speed supported from Jetson Nano and which type of high speed SD card supported by …
