I was reading the ingenic product sheet and see that it supports multiple streams for h264.

Max resolution 2048*2048
Up to H.264 1080P@60fps encode
H.264 multiple streams: 1080P@30fps+D1@30fps+JPEG@15fps
ABR/VBR/CBR/CQP
8 ROIs, 5-layer OSD with hardware

This could be used to run two rtsp servers? Or use the second source to record on board DVR videos?

Can you point me in the right direction about his to tweak the encoder to output two independent streams that can be used simultaneously?

I am trying to get running the motion detection sample.
I have a crash when calling the API IMP_IVS_CreateChn
Any idea how to debug ?
Thanks,

I've been playing with the libimp samples and am wondering what the origin of the libimp binary .so files are (in the uclibc folder). I assume this is a library offered by the vendor to do the video I/O. Is this software open source? If so, somewhere where I can get at it?

Also, I've seen mention of a repository that might have documentation but can't seem to locate it. Can you point me in the direction of where this might be?

hello anyone,
My experience is compiling repository of https://github.com/mpromonet/v4l2web to work on my raspberry pi with camera.
Can i clone & compile this repository on my rapberry and just copy bin output to dafang/xiaofang CFW bin ?
Detail steps would be great.
Thanks.

Is it possible? Can you publish a "how to try to compile everythig?"

Hi @EliasKotlyar , I've tried to compile v4l2rtspserver, but when i run it, i got this error message:

root@Ingenic-uc1_1:mmcblk0p1]# ./v4l2rtspserver /dev/video0
1970-01-01 08:02:19,680 [NOTICE] - /test/v4l2rtspserver/src/main.cpp:548

Do you know how to debug it? So i can fix what's wrong. i've tried to copy the binary to /tmp folder and set chmod 777 and chown root,root the binary, but it remains. Also tried to chmod 777 to the /dev/video0.

Not work -O param

@EliasKotlyar Can you restore -n and -r param?
I know that setconf exist, but for default startup param is good idea with -n and -r available.

Boa ceased development 13 years ago as far as I can tell. Why is it being used instead of busybox’s own httpd?

Hi all,
In the T20 documentation there are some references to opencv.
Did someone have some information ? There is a lib, or something else ?

Thks,

The v4l2rtspserver currently saves images to SDCARD, which can be processed by using a script.
As many other cameras do, direct upload to a remote server could be an interesting feature.
This can be can be achieved by using a script as an hook, which is called after the file is saved. The inconvenient is that the card will be written (frequently?), degrading its life expectancy.
Alternatives, that I can think of are:

• mounting the DCIM folder using TMPFS and then upload the image: works out of the box but will consume a chunk of RAM.
• added support for direct upload in the code (using libcurl?), in a separated thread: adds a dependency to the server, but streamlines the process, while possibly taking much less resources.

Is there a opinion regarding such feature, and how to proceed with it?

@EliasKotlyar,
Is it working fine with this branch ? On Wyse Camera?
I have some troubles making working again the movement detection (maybe the API changed a bit with the latest libs)
We definitely need the latest SDK. I contacted Ingenic, they didn't say "no" but they asking questions and questions, I don't think they will give it to me ...

When launching the v4l2rtspserver-master in the repo it fails with the following message.

i264e[info]: profile Constrained Baseline, level 3.1
/system/sdcard/bin/v4l2rtspserver-master: /home/ptkang/work/platform/isvp_20160504_e/proj/sdk-lv3/src/imp/ivs/ivs_move/src/filter.c: 156: Start: Assertion `filter->roi.x >= 0 && filter->roi.y >= 0 && filter->roi.width >= 0 && filter->roi.height >= 0 && filter->roi.x + filter->roi.width <= filter->wholeSize.width &&filter->roi.y + filter->roi.height <= filter->wholeSize.height' failed.

@EliasKotlyar how did you compile the audio driver ?
I would like to change the audio rec level. I didn't find another way of changing this level.

Thks,

Good afternoon !
Please tell me how I can build a tun/tap driver (tun.ko) for this kernel.
Thank you !

P.S. I write this ask in other repo, sorry.

Hi EliasKotlyar,
I have worked on a OSD display. I am not very familiar with Github, do you want I submit a new branch (I am not sure you want me to push on the master ...)
Thanks,

First things first:
Thanks for this alternative firmware!

I want to use my dafang as additional baby monitor and I don't want the content to leave my network.

I'd like to see only a small part of the wide angle high resolution image that is provided by default. I only need 45 degree FOV even with a lower resolution. To stream the full picture in 1080p and cropping it on the receiver side would be a waste of bandwith.
Is there a way to have a virtual zoom from within the camera?
