CVBS HDMI encoder for live streaming

What is a CVBS HDMI encoder for live streaming?

CVBS HDMI encoder for live streaming is a device that supports CVBS analog TV composite video input and HDMI 1080P high-definition video input; The board output is IP RJ45 and supports RTSP player and UDP player, which means it connects the board to the internet. Your video sources will become the stream and play on the internet.

Q1: Does your CVBS HDMI encoder for live streaming support MPEG-2 TS over UDP supported?

A1: بله. Our CVBS HDMI encoder for live streaming supports MPEG-2 TS over UDP.

Q2: به جای RSTP, I need an MPEG-2 Transport stream

A2: Do you need DVB-t RF out, which supports the Transport Stream?

Q3: خیر, just CVBS input and Ethernet out, Ethernet protocol: H.264. For compression, MPEG-2 TS on UDP broadcast, I need a quote for 5 qty and a complete datasheet.

A3: Vcan1746 can output the TS stream over UDP, but the output TS stream is a non-standard Transport Stream that we have modified, which needs to be interpreted by our decoder board or player.

Q5: What should I do if I can’t ping the encoder board from my computer?

1. I can get the sub-stream quickly, but the mainstream needs to get it after reboot. What should I do?

I have tested your encoder multiple times with our system. It is working fine overall.
But we have one big issue to validate its usage :
Whenever we turn on the system camera and the encoder at the same time, we cannot read the “mainstream”, we can only read the “sub-stream”.
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 reply: 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.

HDMI encoder can detect the video input source
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)

علاوه بر این, 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)
از این رو, 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 theMainstream”, we can only read thesubStream”.

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. مثلا, your camera startup needs 10 ثانیه, but our encoder board startup needs only 5 ثانیه.

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 whyWe have toRebootthe 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.

از این رو, the final suggestions are as follows (I tried my best to list everything that came to mind and let you test them separately);

  1. 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;
  2. It is recommended that you ping the coding board under cmd first, و سپس به mainStream و subStream تحت vlc دسترسی پیدا کنید تا به اشتباه فکر نکنید که Mainstream به دلیل مشکلات تصادفی مک قابل دسترسی نیست..
  3. اجازه دهید ابتدا دوربین خود را روشن کنید (برای چند ثانیه), سپس روشن کنید و برد رمزگذاری ما را شروع کنید تا امتحان کنید (دلایل توضیح داده شده در بالا را ببینید)
  4. عملیات اصلی خود را دنبال کنید “دوربین سیستم و رمزگذار را همزمان روشن کنید”. وقتی مشکل “ما قادر به خواندن آن نیستیم “مسیر اصلی”, we can only read thesubStream”.” تکثیر می شود, برد رمزگذاری را از طریق صفحه وب راه اندازی مجدد نکنید, اما کابل HDMI را بین دوربین خود و برد رمزگذاری گرم کنید. من فکر می کنم این فقط یک عملیات مبادله داغ است (چون فکر می کنم مشکل تشخیص پلاگین است که باعث می شود دوربین به برد رمزگذاری متصل نشود. ارسال سیگنال HDMI)
