    RTSP from Uniview cameras won't play on iPhone

    If I use "-c:v libx264" it works on iPhone If I use "-c:v copy" it does not play on iPhone. It just flashes the first picture or either just plays black screen.

    RTSP from Uniview cameras won't play on iPhone

    I am using FFMPEG to take the RTSP from uniview cameras and turn it into HLS. When I encode the rtsp to libx264 it will play on iPhones. BUT... When I copy the rtsp rather than encoding it... it won't play on iPhones. I just plays black. This is ONLY with uniview.... with all other...

    Any FFMPEG gurus in here?

    Thank you! I really appreciate your time! Thanks for writing all that out. When I replaced libx264 with copy it make the CPU performance amazing! I think it also helped me get on the right path toward solving an issue we have an uniview rtsp now playing on iOS. Thanks again.

    Thanks for the replies! Here is the command I am running. This is running on a small VPS. Latest versions of Ubunutu, Apache, & FFMPEG. This command takes up 60-70% of the CPU! This is just streaming one camera from RTSP to HLS. Any tips? ffmpeg -i...

    Any FFMPEG gurus in here?

    Is anyone in here good at FFMPEG? I have a command that takes rtsp and streams it to HLS but... The CPU performance is horrible. I wonder if that is just the way it is... or if it is possible to tune it and make it perform well. Trying to stream multiple cams via hls on a vps...

    Dahua - no GOP setting

    Sorry! I just found that the NVR does not have the Iframe Int setting BUT when I log right into the camera it is there. Do you have any suggestions about the Iframe Int setting? Our HLS is having artifacts behind motion. By default the Iframe Int is dobule the FPS. What would you suggest...

    Dahua - no GOP setting

    Help! We run the rtsp from Dahua cameras through our custom built streaming server which turns the RTSP into HLS for display on all devices. Has worked great for 2 years but now with the latest Dahua nvr and cameras we have ghosting / artifacts behind motion. I notice that there is no setting...

    Get P2P qr code via Dahua API

    Its just the serial number. I guess I also need to be able to enable and disable p2p via API as well... I dont see that in there either... But I have no idea if I am using the newest version of the API... or how to even get it. :)

    NodeJS Module: node-dahua-api

    Anyone know if there is a way to enable / disable p2p via the api? Also, is there a way to grab the QR code via api? I am trying to create a web based playback experience similar to what the user gets if they are standing at the dvr. Do you guys think this api is sufficient for that?

    Bypass port forwarding

    @catcamstar thanks for the tip. what we would need to do is have the pi or wifi router allow only the mac address of the camera. the use care is: a simple 1 camera job that the user can easily move around the house... like a nest cam... just plug the camera into power. thanks everyone! i...

    Bypass port forwarding

    right right.... the PI is a tiny linux box... I did not know you could turn it into a wifi router though... I will have to look that up. Thanks!

    Bypass port forwarding

    Yes! That is exactly what I am trying to do! The camera would have to connect to the PI though. Either through ethernet or wifi. How would the camera get an ip address because the PI does not do DHCP does it? If the PI was a mini wifi router that would be perfect. :)
