Input Video URL (GStreamer)

How it fits

Typical backends

Caveats

• Hard constrainturl must use an `http(s)://`, `rtsp(s)://`, or `rtmp(s)://` scheme and contain only standard URL characters. Any other scheme or special character is rejected — the component produces no frames and retries after retry_delay_ms.
• Parameter interactiongst_backend overrides URL routing and accepts a full GStreamer pipeline description. It is not URL-validated; set it only to a trusted pipeline string. When set, url is ignored.
• Parameter interactionWhen gst_backend is empty, the component builds a GStreamer backend for HTTP MJPEG, RTSP, RTMP, and generic URI sources.
• CompatibilityDecoding goes through GStreamer, so the available transports and codecs depend on the GStreamer plugins present in the runtime. For FFmpeg-native URL decoding prefer input_video_url_ffmpeg.
• FallbackFailed backends reconnect after retry_delay_ms milliseconds.
• Parameter interactionwidth and height `0` preserve the source resolution; either non-zero triggers a resize. Aspect ratio is NOT preserved automatically.
• Parameter interactiondrop_frames `true` drops frames when downstream is slower; `false` blocks the producer.
• State lifetimeAll six config keys are hot-swappable; a url or gst_backend change tears down the current pipeline and re-opens.
