+# HTTP
+
+This source supports receiving a stream via an HTTP link.
+
+It can determine the source format from the`Content-Type` HTTP header:
+
+- **HTTP-JPEG** (`image/jpeg`) - camera snapshot link, can be converted by go2rtc to MJPEG stream
+- **HTTP-MJPEG** (`multipart/x-mixed-replace`) - A continuous sequence of JPEG frames (with HTTP headers).
+- **HLS** (`application/vnd.apple.mpegurl`) - A popular [HTTP Live Streaming](https://en.wikipedia.org/wiki/HTTP_Live_Streaming) (HLS) format, which is not designed for real-time media transmission.
+
+> [!WARNING]
+> The HLS format is not designed for real time and is supported quite poorly. It is recommended to use it via ffmpeg source with buffering enabled (disabled by default).
+
+## TCP
+
+Source also supports HTTP and TCP streams with autodetection for different formats:
+
+- `adts` - Audio stream in [AAC](https://en.wikipedia.org/wiki/Advanced_Audio_Coding) codec with Audio Data Transport Stream (ADTS) headers.
+- `flv` - The legacy but still used [Flash Video](https://en.wikipedia.org/wiki/Flash_Video) format.
+- `h264` - AVC/H.264 bitstream.
+- `hevc` - HEVC/H.265 bitstream.
+- `mjpeg` - A continuous sequence of JPEG frames (without HTTP headers).
+- `mpegts` - The legacy [MPEG transport stream](https://en.wikipedia.org/wiki/MPEG_transport_stream) format.
+- `wav` - Audio stream in [WAV](https://en.wikipedia.org/wiki/WAV) format.
+- `yuv4mpegpipe` - Raw YUV frame stream with YUV4MPEG header.
+
+## Configuration
+
+```yaml
+streams:
+  # [HTTP-FLV] stream in video/x-flv format
+  http_flv: http://192.168.1.123:20880/api/camera/stream/780900131155/657617
+  
+  # [JPEG] snapshots from Dahua camera, will be converted to MJPEG stream
+  dahua_snap: http://admin:password@192.168.1.123/cgi-bin/snapshot.cgi?channel=1
+
+  # [MJPEG] stream will be proxied without modification
+  http_mjpeg: https://mjpeg.sanford.io/count.mjpeg
+
+  # [MJPEG or H.264/H.265 bitstream or MPEG-TS]
+  tcp_magic: tcp://192.168.1.123:12345
+
+  # Add custom header
+  custom_header: "https://mjpeg.sanford.io/count.mjpeg#header=Authorization: Bearer XXX"
+```
+
+**PS.** Dahua camera has a bug: if you select MJPEG codec for RTSP second stream, snapshot won't work.
