Video problem about bananapi-m2-zero-ov5640 HOT 10 OPEN

@crudo0-arch,

Could you get the 1080 x 720 UDP stream working?
It's given as an example in the Readme.

from bananapi-m2-zero-ov5640.

The UDP from the example gives this output:

gst-launch-1.0 -v v4l2src device=/dev/video1 num-buffers=-1 ! video/x-raw, width=1280, height=720, framerate=30/1 ! videoconvert ! jpegenc ! rtpjpegpay ! udpsink host=192.168.1.54 port=5200

but on VLC i the streaming did not start... The streaming to desktop command on the page gives this output:

when we tryed the opencv script it gives this:

@crudo0-arch,

Several things come into play here.

You only have a small amount of RAM on board.
500Mb gives you little space, all the more so because the Armbian OS also consumes a part.
We just managed to send 1280x720@30FPS UDP, 1280x960 is no longer possible.

You probably don't have enough memory to record video. Remember that mp4, flv or mkv are all h264 encoded. This compression is too demanding for the BananaPi zero, especially if you run it via OpenCV.

We just managed to record a simple avi with this pipeline.

gst-launch-1.0 -v v4l2src device=/dev/video1 num-buffers=-1 ! video/x-raw, width=1280, height=720, framerate=15/1 ! videoconvert ! jpegenc ! avimux ! filesink location=video.avi

I think you'll have to adjust your expectations.

P.S. Your UDP test failed because you use the wrong receiver pipeline.

whit the metioned pipline i get

there's a way to boot on CLI and increase the swap memory?

from bananapi-m2-zero-ov5640.

Unfortunately you can't boot on CLI. Not sure if more swap space will solve anything here. 4 GB is a lot
BTW, how much memeory do you have available after a reboot, not running any app? $ free -m

from bananapi-m2-zero-ov5640.

so there's no way to turn the banapi on a wifi hd camera??

from bananapi-m2-zero-ov5640.

I don't think so.

from bananapi-m2-zero-ov5640.

the raspberry pi zero has 512mb of ram but it can work as a videcamera...

from bananapi-m2-zero-ov5640.

Indeed.

Your problem is the lack of proper video software tailored to the hardware.
The Raspberry Pi foundation has many programmers, some solely working on the Broadcam video stack.

The BananaPi only has a forum; several enthusiastic Linux programmers are trying to build extensions.
The problem is that there is not one generic operating system but many. Every operating system has its fans. And there is no coordination between jobs.

You end up with several operating systems, all more or less doing something, but (usually) without any solid foundation or documentation. It is the case with many boards, such as the Orange Pi, Rock Pi, and VIM3, not just the Banana Pi.
Make money by selling hardware. But developing proper software is more or less left to a forum.

I'm sure the Banana PI will eventually be able to handle HD video over WiFi. You will have to develop your own GPU driver software at a very low level
