    6. Broadcast to OBS Studio using LTE/5G

    If your PC has a public IP address, you can use the SRT streaming as mentioned above.

    However, if your PC has a private IP, port forwarding is required.

    For how to manual of the port forwarding, please click here.

    After the port forwarding, write the private IP address in OBS and write the public IP of your PC in CameraFi Live.

    Please keep in mind that you need to use the port number which is port forwarded. The image below will explain the process of streaming video from CameraFi Live to OBS using SRT.

    7. Resolution / Encoder Format Settings

    In the Settings option on the right top, you can set the IP address, resolution, encoder format, etc.



    As the supported resolution option might vary depending on your smartphone model. The explanation below is based on the Galaxy S20 Ultra 5G.

    • Free users: 480p, 720p, 1080p
    • Premium users: Including the free user options, 60fps or 1440p and 2160p is available.

    According to the test from the CameraFi Live team, the delay time was about 1 to 2 seconds, and there was no difference between the delay time when set to 1080p resolution.

    [Encode Format]

    How about the encoder formats?

    CameraFi Live supports the encoder format of H.264 and HEVC.

    We compare H.264 and HEVC encoder formats at 1080p/60fps.

    The delay time was about 1 second longer in the HEVC encoder format. However, with the HEVC encoder format supports the higher quality in the poor wireless environment.

    We recommend HEVC rather than H.264 for the users who use high-performance smartphones and are okay with a 1-second delay.

    If you have any questions about the SRT streaming, please leave us the comment below.

    Thank you.
