şîfrekera vîdyoyê dekoder

1. Vcan1681 supports SDI and PAL.

2. We have two firmware to support H265 and H264 encoder and decoder.

1. Max supports 1080P.
2. HDMI input supports 4k.

We need to ask the engineer, please tell us the details of the video decoder if you have.
We also have video encoder and decoder board, if you both us ours, then it is no problem.

The video bitrate is configurable by the customer (bikaranîvan).

Do you mean HDMI or AV input (support two video types), or do you need HDMI and AV to support two simultaneous inputs?

Q: We need to have HDMI and AV to support two simultaneous inputs.
YEK: Ok. Our firmware engineer will some days to make a new firmware to meet this function you need. I will upgrade it and show you the test video. https://youtu.be/izdFa1nw7u8

iVcan: Please help to confirm that HDMI and cvbs can be supported at the same time, but the audio can only be selected from one of the two (the system selects HDMI audio/analog audio according to the video access situation), is it ok for you?

Kirrîxwaz: We don’t need audio, so do what is the best for you.

iVcan: Our software engineer has made a software for you. Please check the pictures in the attachments.
Now it supports an HDMI camera and CVBS camera.

Kirrîxwaz:
I have tested your encoder multiple times with our system. It is working fine overall.
But we have one big issue to be able to validate its usage :
Whenever we turn on the system Camera and the encoder at the same time we are unable to read the “mainStream”, we can only read the “subStream”.
We have to “Reboot” the encoder via the web interface to make it work: after the reboot we can directly read the mainStream.
We tried with both VLC and GStreamer.
What could we try to have both streams readable on startup ?

iVcan:
In the opinion of our engineers, it is either a problem with camera recognition or a problem with customer use.
I suspect that the board card did not recognize the customer’s HDMI camera.
This is easy to verify (if you cannot access the sub-stream, it will be difficult to verify).
Log in to the web server of the encoder board and you can see the camera recognition status on the video page.

iVcan:
The video page will only display the recognition status of one camera. If HDMI and AV cameras are connected and recognized at the same time, the video page will display the recognition status of the HDMI camera (such as 1080p60):
As long as the HDMI camera can recognize it normally, Mainstream can be accessed normally.
If the HDMI camera is not recognized normally, please check the HDMI wiring and power on the board again (note that this is a power cycle, not a software restart on the web page)
Herwisa, the board uses a random Mac address, so the Mac address will change every time we restart it.
For devices with an ARP cache (such as a PC), after restarting, it will be temporary (a few seconds) unable to access the board from the network. , We cannot access it until the arp request is re-initiated after timeout (the performance is that the coding board cannot be pinged for several seconds after restarting)
Ji ber vê yekê, I guess another possibility is that when the customer accesses the mainstream, it cannot be accessed due to the above reasons. Then when the customer accesses sub-stream, the arp cache refreshes and the customer can access it, but the customer does not revisit the main-stream.

"Whenever we turn on the system camera and the encoder at the same time, we cannot read the “Mainstream”, we can only read the “subStream”."

iVcan:
Judging from your description here, it seems that your camera is started after our encoding board. Please start your camera first, and then power on and start our encoding board to try it. Maybe it is not powered on at the same time. The powered-on order also matters. Bo nimûne, your camera startup needs 10 seconds, but our encoder board startup needs only 5 seconds.
Because I am not sure whether your camera is very slow to initialize after power-on.
Because our encoder board starts very quickly, it may be that the camera has not been initialized after it started our encoder board, which may lead to some unexpected problems. This can also explain why “We have to “Reboot” the encoder via the web interface to make it work: after the reboot we can directly read the mainStream.”, because when your web page restarts the encoder board, the camera has already been initialized.
Ji ber vê yekê, the final suggestions are as follows (I tried my best to list everything that came to mind and let you test them separately);
Look at the video page of the web server and confirm whether the HDMI camera is recognized normally (you can send a screenshot to us). As long as the camera is recognized normally, Mainstream can be accessed;
It is recommended that you ping the coding board under cmd first, û dûv re xwe bigihînin mainStream û subStream di binê vlc de da ku bi xeletî nefikirin ku Mainstream ji ber pirsgirêkên mac-ya rasthatî nayê gihîştin.
Bila hûn pêşî dest bi kameraya xwe bikin (ji bo çend saniyeyan), dûv re hêz bidin û dest bi panela meya kodkirinê bikin ku hewl bidin (sedemên ku li jor hatine diyarkirin bibînin)
Operasyona xweya orîjînal a "di heman demê de kameraya pergalê û şîfrekerê vekin" bişopînin. When the problem “we are unable to read the “mainstream”, em tenê dikarin "subStream" bixwînin." tê dubarekirin, Bi navgîniya rûpela malperê panela kodkirinê ji nû ve dest pê nekin, lê kabloya HDMI-yê di navbera kameraya xwe û panela kodkirinê de germ bikin. Ez difikirim ku ew tenê operasyonek guheztina germ e (ji ber ku ez guman dikim ku ew pirsgirêkek vedîtina pêvekê ye ku dibe sedem ku kamera bi panela kodkirinê ve neyê girêdan. Signal HDMI bişînin).

Kirrîxwaz:
Ez her gav dikarim subStream bixwînim. Stream sereke tenê piştî ji nû ve destpêkirinê.

iVcan:
Dûv re panela meya şîfreker dikare kameraya we bibîne.
Ji kerema xwe testek bikin.
Bila hûn pêşî dest bi kameraya xwe bikin (ji bo çend saniyeyan), dûv re hêz bidin û dest bi panela meya kodkirinê bikin ku hewl bidin.
Endezyar ji ber hewcedariya destpêkirina kameraya we fikar e 10 seconds, but our encoder board startup needs only 5 seconds.
Ji kerema xwe vê ceribandinê bikin da ku îhtîmala demên destpêkirina cûda derxînin.

iVcan:
Dema ku hûn ceribandinê dikin, çêtir e ku meriv mîhengê paşde vegerîne (peyvên sor) an jî wêneya jêrîn bibînin.

Kirrîxwaz:
Tabloya şîfreker û kamera her du tam di heman demê de têne çalak kirin. Ihtimal e ku destpêkirina kamerayê ji panela şîfrekirinê hinekî dirêjtir digire.

I confirm that the camera seems to be not recognized on startup “CVBS pal” is displayed at the top.

Berî ku ez hewl bidim ku her du çeman bixwînim ez dikarim panelê baş ping bikim

Dema ku ez yekem kamera xwe dest pê dikim (ji bo çend saniyeyan), paşê hêz bike (15 seconds paşê) û dest bi tabloya kodkirinê bikin, Ez dikarim herikînê baş bixwînim.
If I “turn on the system camera and the encoder at the same time”. Û paşê HDMI-ê germ bikin (15 seconds paşê), Ez dikarim herikînê baş bixwînim.

Ez dikarim çi bikim da ku ez bikaribim mainStream-ê bêyî ku ez van tiştan bikim bixwînim ? Bi nermalava min re rebootek daxwazek http bişînin, çend saniyeyan piştî destpêkirinê ?

iVcan:
Baş, ku texmîna min rast îspat dike. Ji bo xerîdarên me yên din, kamera û panela meya kodkirinê hemî di heman demê de têne çalak kirin. Kamera dikarin panela kodkirina me bi gelemperî nas bikin û sînyalên HDMI bişînin. Tenê çend xerîdar bi karanîna kamerayên xweyên HDMI-ya xwerû bi pirsgirêkên weha re rû bi rû mane. Ya jêrîn ji hêla xerîdar bixwe ve têne çareser kirin (modifying their camera settings/changing cameras).

Kirrîxwaz:
Do you have the version of the software you develop for us? We will precise it in our PO.

iVcan: The firmware version is v6.5.5a for your device.

1. From the photo you showed, we found that the capacitor and inductor in the lower left corner were damaged due to external force. Perhaps they were knocked off during packaging and transportation, and your company accidentally knocked them off during operation.

The highlighted ones are the missing devices, which are:
1、C176：CAP,10NF,+/-10%,X7R,1000bike,SMD1206
2、C21：CAP,22UF,+/-20%,X5R,6.3bike,SMD0603
3、R34：FB,120R@100M,+/-25%,3YEK,SMD0603 （magnetic beads）

Please try to find the same parts, replace them and then check carefully to see if there are any other missing parts.

If you still have questions, ji kerema xwe bi me re têkilî.

Kirrîxwaz:
ev beşa xelet ji bo xebitandina kîjan çerxê tê bikar anîn?

iVcan:
1.5Têrkirina hêza xwe, hêzkirina DDR， ji kerema xwe wêneyê jêrîn kontrol bikin.

Kirrîxwaz:
Me li gorî şîreta we pêkhateyan guherand, encoder ne fonksîyonel e.
Herwisa, me pirsgirêkên din ên kalîteyê yên bi welds re destnîşan kir, çend reworks manual.
Em çawa dikarin bi danûstendinek standard di bin garantiyê de bimeşin?

iVcan:
Xem neke, ji kerema xwe ji me re bişînin, û em ê ji bo we yekî nû biguherînin.

The engineer said that the ONVIF protocol is not fully supported. It depends on your specific requirements.
The video player supports RTSP, VLC, Easyplay, and protocol support UDP player.

Our video encoding board supports two channels of video at the same time, one is HDMI video stream and CVBS video stream encoding.
