hi are two elgato capture card output yuyv or mjpg? I cant get over 11fps using h264_omx.Thanks!

Hey i try to setup a SRT stream with Raspberry 4 and USB Capture Card. My proplem i have only 5 fps. Can i write you DM or have discord ?

[@sskerry101]

Question for you, I have basically replicated your setup but using a cheaper USB HDMI Capture card. It outputs either with MJPEG or YUYV422 - I cannot seem to get the framerate higher than 20 FPS @ 1280x720. In your code I don't see that you are specifying which input format you are using with the CAMLINK. I'm wondering if you could let me know? I think I am hitting a limitation with hardware, but I want to check.

I use OMX I have compiled ffmpeg to support srt with OMX also www.undergroundnews.dk/index.php/item/128-rpi4-ffmpeg-with-srt-on-raspbian-gnu-linux-10-buster

[@djagustinllorente]

Hello, I am using a grabber like you. Could you please provide me with the code you use to transmit? I can't find it

[@djronancoficial]

Hello!! thanks for share this, how did you do this ? i mean, which raspberry pi imagem i can download to run the same here? i am try to setup a remote production srt feed uswing raspberry, thanks!

[@undergroundnews_dk]

You can use any linux image for Raspberry - you can even find a docker container solution possible with srt setup but I compiled srt and also my ffmpeg , At home/office the rpi just use the local wifi and select destination ip for the srt and on the street the rpi just use the mobile wifi and pick another destination. I can use the wifi network to assign destination for the srt - to make it easy to change between destinations but no fancy gui - just terminal or vnc som setup from the phone or tablet.

I tired to see if possible to use Pi 4 camera and transform it into SRT camera, is it anyone had an experience for that ?

[@undergroundnews_dk]

RaspberryPI can do this with any camera that connects - I would recommend the lates 32bit Rasbian because the OMX encoder work. Also you do not ned to compile SRT tools but can do apt get install - but a compilation would give you a newer srt version.

[@djagustinllorente]

Hi, I am using a low cost hdmi 3.0 grabber, could you please give me the line of code you are using to transmit? I've already installed FFMPEG and SRT, but can't find the code to cast to SRT. Thank you very much and excellent project

[@ZillionPrey]

Learn how both works then You'll easily be able to compile a code.

Camlink pi camera is sending to rtmp? Any english write up? I want to do this using usb modems and 1 camlink +camera to rtmp

[@undergroundnews_dk]

its possible to do rtmp and rtmps also using ffmpeg - only for the srt protocol you need to recompile but rtmp with camlink, and usb modem is possible. my rpi4 uses a shared wifi on the mobile to streamout - you can find alot of guides on howto use a usbcam to make rtmp.

[@sidonkodraliu]

Can you make a guide on how to setup a server for SRT and how to stream to that and receive feed trough OBS?

[@undergroundnews_dk]

New version of OBS does support srt - I in older version it was not working for and used srt-to-live to make output to UDP but now you can just add a media source non local and select srt://:4000?mode=listerner Did have problems with ubuntu 20.04 and older OBS 25.0 but its running fine now.

[@lilitdk]

@@undergroundnews_dk with obs you dont need a server - just port forward to the obs computer or you can do srt to rtmp like this echo "Do srt to rtmp" while true; do ffmpeg -i "srt://:4005?mode=listener&passphrase=passwords" -c copy -f flv rtmp://192.168.10.191:1942/live/external.stream?token=xy done echo "srt2rtmp --- Stop"
