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: Kas teie CVBS HDMI encoder for live streaming support MPEG-2 TS over UDP supported?

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

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

Q3: ei, 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?

Directly connect the Kodeerimisplaadi UART-kaabel arvutisse, and use the serial port debugging assistant to send the ATGIP_ command. Get IP address command Operatsioonivideo Youtube'is

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

Olen teie kodeerijat meie süsteemiga mitu korda testinud. Üldiselt töötab hästi.
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.
Mida võiksime proovida, et mõlemad vood oleksid käivitamisel loetavad?

iVcan reply: Meie inseneride arvates, see on kas kaamera tuvastamise või kliendi kasutamise probleem.

Kahtlustan, et tahvelkaart ei tundnud ära kliendi HDMI-kaamerat.
Seda on lihtne kontrollida (kui te ei pääse alamvoogu juurde, seda on raske kontrollida).
Logige sisse kodeerijaplaadi veebiserverisse ja näete video lehel kaamera tuvastamise olekut.

HDMI encoder can detect the video input source
Videolehel kuvatakse ainult ühe kaamera tuvastamise olek. Kui HDMI- ja AV-kaamerad on ühendatud ja tuvastatud samal ajal, videolehel kuvatakse HDMI-kaamera tuvastamise olek (näiteks 1080p60):
Kuni HDMI-kaamera suudab selle normaalselt ära tunda, Põhivoolule pääseb tavapäraselt juurde.
Kui HDMI-kaamerat ei tuvastata normaalselt, palun kontrollige uuesti plaadi HDMI-juhtmestikku ja toidet (Pange tähele, et see on võimsustsükkel, mitte tarkvara taaskäivitamine veebilehel)

Lisaks, tahvel kasutab juhuslikku Maci aadressi, nii et Maci aadress muutub iga kord, kui selle taaskäivitame.
ARP-vahemäluga seadmete jaoks (nagu arvuti), pärast taaskäivitamist, see on ajutine (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)
seega, 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”, saame ainult lugeda “alamvoog”.

Judging from your description here, it seems that your camera is started after our encoding board. Please start your camera first, ja seejärel lülitage sisse ja käivitage meie kodeerimisplaat, et seda proovida. Võib-olla pole see samal ajal sisse lülitatud. Samuti on oluline sisselülitatud järjekord. Näiteks, teie kaamera käivitamine vajab 10 sekundit, kuid meie kodeerijaplaadi käivitamiseks on vaja ainult 5 sekundit.

Kuna ma pole kindel, kas teie kaamera lähtestub pärast sisselülitamist väga aeglaselt.
Kuna meie kodeerijaplaat käivitub väga kiiresti, võib juhtuda, et kaamerat pole pärast kodeerijaplaadi käivitamist lähtestatud, mis võib põhjustada ootamatuid probleeme. This can also explain why “Me peame “Taaskäivitage” kodeerija veebiliidese kaudu, et see töötaks: after the reboot we can directly read the mainStream.”, sest kui teie veebileht taaskäivitab kodeerijaplaadi, kaamera on juba lähtestatud.

seega, viimased soovitused on järgmised (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, and then access mainStream and subStream under vlc to avoid mistakenly thinking that Mainstream cannot be accessed due to random mac issues.
  3. Let you start your camera first (for a few seconds), then power on and start our encoding board to try (see the reasons described above)
  4. Follow your original operation ofturn on the system camera and the encoder at the same time”. When the problemwe are unable to read the “põhivoog”, saame ainult lugeda “alamvoog”.” is reproduced, Do not restart the encoding board through the web page, but hot-swap the HDMI cable between your camera and the encoding board. I think it is only a hot-swap operation (because I suspect it is a plug-in detection problem that causes the camera not to connect to the encoding board. Send HDMI signal)
