Render RTSP Streams on to a Web Browser (WebRTC) using GStreamer

[Eslam Ahmed]

Hi,

1) Yes, you can. Gstreamer can encode/decode H264/H265 using Nvidia GPUs by
using those elements nvv4l2decoder/nvv4l2h264enc/nvv4l2h265enc.
2) Yes, you can. If there's no reason to transcode, say to rescale or
overlay something on the stream, then the implementation here `
https://github.com/WebRTSP/ReStreamer`  would just relay the H264/H265
encoded packets as is without decoding yielding trivial CPU usage. The
decoding is by  the webrtc client/browser.
3) https://github.com/WebRTSP/ReStreamer  >> This is ready-to-use IP Camera
stream to WebRTC (does no transcoding by default, just relay!)

Best Regards,
Eslam Ahmed
