@ -291,6 +291,13 @@ This has the following parameters:
``w``, ``h``
For video codecs: expected video size. See ``codec`` for details.
``fps``
For video codecs: expected video framerate, as integer. (The rate is usually
only crudely reported, and it makes no sense to expect exact values.)
``samplerate``
For audio codecs: expected sample rate, as integer.
The ``delay_open`` header is not part of the core EDL format. It may be changed
or removed at any time, depending on mpv's internal requirements.
