[REQ] live streams (RTSP TCP/UDP) input support #144

Closed MarcoRavich closed 3 months ago

MarcoRavich commented 1 year ago

Hi there, as always thanks for your great work.

Recently we're dealing with (4-8) RTSP streams - coming through LAN from our PTZ cameras that we use in live performances shootings - so, since your *Encs can de/en-code much faster than realtime, we wonder if it is possible to feed them directly providing streaming links.

It would be extremely useful both for acelerated decoding (live display) and/or recording: this could push the adoption of *Encs as backend by several open NVR/NetPlayer projects.

Hope that ispires.

QSVEncC can grab live streaming like ffmpeg, as it supports libavformat.

Simple example is shown below.

x64\QSVEncC64.exe -i rtsp://<ip address>:<port>/mystream -o F:\temp\test.ts --audio-codec aac

Cool (does this means that it can be feeded from capture card too ?), didn't get it.

....another question: can QSVEncC be used as a "hw decoding engine" only ?

To be more clear: can it be replace ffmpeg in this kind of script ?

Thanks in advance !

It will be interesting Zoneminder with QSVEncC

I've adjusted the behavior for camera input, QSVEnc 7.40 should be able to capture "dshow" camera input.

x64\QSVEncC64.exe --input-format dshow -i video="<webcam>" -o output.mp4

QSVEncC be used as a "hw decoding engine" only ?

Unfortunately not, QSVEncC is designed to be used as a encoder. Also, it's design is to be able to handle single video stream. It will be difficult to re-design it to handle multiple video streams.
