Python function

probe_video

probe_video()

max.pipelines.context.probe_video(source)

source

Reads a video’s header without decoding any frame.

Parameters:

source (str | bytes) – The video to probe.

Returns:

The stream metadata. num_frames is the header’s best-effort count and may be 0 or simply wrong; decode_video_frames() corrects it against the frames a decode actually produces.

Raises:

MediaDecodeError – If the source is not a readable video.

Return type:

VideoStreamInfo
