go2rtc

Appearance

MP4 ​

This module provides several features:

  1. MSE stream (fMP4 over WebSocket)
  2. Camera snapshots in MP4 format (single frame), can be sent to Telegram
  3. HTTP progressive streaming (MP4 file stream) - bad format for streaming because of high start delay. This format doesn't work in all Safari browsers, but go2rtc will automatically redirect it to HLS/fMP4 in this case.

API examples ​

  • MP4 snapshot: http://192.168.1.123:1984/api/frame.mp4?src=camera1 (H264, H265)
  • MP4 stream: http://192.168.1.123:1984/api/stream.mp4?src=camera1 (H264, H265, AAC)
  • MP4 file: http://192.168.1.123:1984/api/stream.mp4?src=camera1 (H264, H265*, AAC, OPUS, MP3, PCMA, PCMU, PCM)
    • You can use mp4, mp4=flac and mp4=all param for codec filters
    • You can use duration param in seconds (ex. duration=15)
    • You can use filename param (ex. filename=record.mp4)
    • You can use rotate param with 90, 180 or 270 values
    • You can use scale param with positive integer values (ex. scale=4:3)

Read more about codecs filters.

PS. Rotate and scale params don't use transcoding and change video using metadata.

Snapshot to Telegram ​

This examples for Home Assistant Telegram Bot integration.

  • change url to your go2rtc web API (http://localhost:1984/ for most users)
  • change target to your Telegram chat ID (support list)
  • change src=camera1 to your stream name from go2rtc config

Important. Snapshot will be near instant for most cameras and many sources, except ffmpeg source. Because it takes a long time for ffmpeg to start streaming with video, even when you use #video=copy. Also the delay can be with cameras that do not start the stream with a keyframe.

Snapshot from H264 or H265 camera ​

yaml
service: telegram_bot.send_video
data:
  url: http://localhost:1984/api/frame.mp4?src=camera1
  target: 123456789

Record from H264 or H265 camera ​

Record from service call to the future. Doesn't support loopback.

  • mp4=flac - adds support PCM audio family
  • filename=record.mp4 - set name for downloaded file
yaml
service: telegram_bot.send_video
data:
  url: http://localhost:1984/api/stream.mp4?src=camera1&mp4=flac&duration=5&filename=record.mp4  # duration in seconds
  target: 123456789

Snapshot from JPEG or MJPEG camera ​

This example works via the mjpeg module.

yaml
service: telegram_bot.send_photo
data:
  url: http://localhost:1984/api/frame.jpeg?src=camera1
  target: 123456789
