Works like a charm! This is the stream i tried with audio and video: gst-launch-1.0 -e v4l2src num-buffers=512 ! video/x-raw,format=NV12,width=1920,height=1080,framerate=30/1 ! queue ! mpph264enc ! queue ! h264parse ! mp4mux0. autoaudiosrc ! audio/x-raw,width=16,depth=16,rate=44100,channel=1 ! queue ! audioconvert ! audioresample ! voaacenc ! aacparse ! mp4mux ! filesink location=/home/linaro/testh264-2.mp4 To give other newbies like myself a little more to work on here is the layout, as I understand it. gst-launch-1.0 -e v4l2src num-buffers=512 ! video/x-raw,format=NV12,width=1920,height=1080,framerate=30/1 ! queue ! // this sets the camera source as v4l2 and will stop after 512 buffers have been used (approx 4 minutes ) raw vidoe stream is NV12 1920x108 with 30 fps, pretty obvious, add queue to let the computer keep working the camera while it encodes // mpph264enc ! queue ! // right !encode h.264 via hardware. Nice! h264parse ! // parse for muxing mp4mux0. autoaudiosrc ! // link the video and audio mux for intended parcel format, in this case mp4 audio/x-raw,width=16,depth=16,rate=44100,channel=1 ! queue ! audioconvert ! audioresample ! voaacenc ! aacparse // add audio source and encoding ! mp4mux ! f// mux it together into one file filesink location=/home/linaro/testh264-2.mp4 // sink file where your video will end up! Presto!

Thanks Tooz! This is what I needed. Cheers!

Has anyone figured out how to include hardware encoding in video recording? Especially in Gstreamer. I have researched for weeks and found very little useful information. It seems tinker board and other rock chip based boards just do not have the support for it, but many of the posts are old. Anything?

The problem is that like most other MD solutions it compares frames. That's a pretty CPU heavy operation. With picamera and mmal you could extract motion vectors directly (somehow) and use those = less CPU intensive. See pikrellcam Alas, this is not possible with v4l2.

Thanks, i have looked into that and gstreamer appears to have it's own motion detection addon. I will explore it further once i have figured out hw encoding so I can get decent framerate and resolution. Damn it, my old Pi gets 720p and 20 fps without laggy vids and dropped frames! Gstreamer motion detection https://developer.ridgerun.com/wiki/index.php/GStreamer_Background_Subtraction_Camera-Based_Motion_Detection_Plugin https://forums.developer.nvidia.com/t/motion-vectors-in-gstreamer/167290/4 https://gstreamer.freedesktop.org/documentation/opencv/motioncells.html?gi-language=c

Thanks! After much research I have found that mmal is pretty much specific for raspberry pi and pi camera. Ffmpeg does not currently work with most rock boards, at least not with video encoding. So Gstreamer it is. If anyone know how to extract motion vectors with gstream or other compatible program, please point me in the right direction. I want to do motion detection, and not the CPU heavy way of comparing jpegs.

In short: ffmpeg can be used to capture audio but not video because the current libraries are not compatible with the setup.

Thanks! I'll do that!

Is am trying to get program working on tinker board r2 or s2 with recommended OS. But I am having issues because I am used to raspberry pi and piOS Is there any of the shared libraries that correspond to the following piOS libraries: libbcm_host.so => not found libvcos.so => not found libmmal.so => not found libmmal_core.so => not found libmmal_util.so => not found libmmal_vc_client.so => not found these are libraries referring to the use of the pi camera.

Here is my version of python-gstreamer dvr. You need to install the python-gst bidnings though: pythong dvr -records 60s video - I have to fix the pipeline though because the clips are really big. 2+ gigs per minute dvr60s-dated.py

I have a tinkerboars r2 (and a TB 2s) with recommended OS. I have attached a picamerav2 (8MP imx219) and it works with gstreamer but I have yet to learn that. I cannot get ffmpeg working, I just get the message: [video4linux2,v4l2 @ 0x810f7610] Not a video capture device. /dev/video1: No such device Using: ls /dev/video* I get: /dev/video0 /dev/video1 /dev/video2 /dev/video3 /dev/video4 so clearly the camera is recognised by the system Has anyone got ffmpeg working on TB os?

I think you can use gstreamer from python. I have just started exploring this myself so I am not sure yet. https://brettviren.github.io/pygst-tutorial-org/pygst-tutorial.html https://sahilchachra.medium.com/all-you-want-to-get-started-with-gstreamer-in-python-2276d9ed548e

Has anyone succesfully installed Pikrellcam ( https://github.com/billw2/pikrellcam) on a tinker board? You may have to revise the installation script a bit and change the php version. although I think the buster version for TB is still 7,3
