Convenience function for returning an audio format.

Returns media with the contents of the file f.

f should be a value that can be coerced to a file via clojure.java.io/file.

Returns media with only audio streams from media.

Returns media with only types in media-types.

Returns media with only video streams from media.

Returns a reducible of frames of media.

Stream can either be:

• an index
• :audio, which selects the first audio stream.
• :video, which selects the first video stream.

opts is an optional map with the following keys: :format A media format description as returned by audio-format or video-format. The frames will be transcoded to the provided format if not already in that format.

Returns a collection of available codecs.

Returns an opaque, raw frame for creating media with make-media.

The following keys are required: :format: map describing the format returned by audio-format or video-format. :bytes: a byte array with the raw data adhering to :format. :time-base: a ratio of that pts will be specified in. :time-base typically matches the frame rate for video or sample rate for audio.

          `time-base` can specified using 3 different methods:
           - as a ratio: (eg. 1/60)
           - as a 2 element vector of [numerator, denominator]: (eg. [1 60])
           - as an integer. It will be treated as 1/time-base: (eg. 60).

:pts: the presentation timestamp in :time-base units. (time in seconds) = pts * time-base.

The following keys are optional: :key-frame?: specifies whether the current frame should be a key frame.

Returns media using raw data found in frames. frames must be a sequence of frames created with make-frame.

All possibel pixel formats.

Plays the first audio stream in media.

Reads the file f and returns metadata about the media's format.

f Any value that can be coerced to a file via clojure.java.io/as-file.

Returns media without audio streams from media.

Returns media without any types in media-types.

Returns media without video streams from media.

All possible sample formats.

Returns media that combines all the streams from medias.

Convenience function for returning an audio format.

Write media to the path given by dest.

opts can have the following options:

:audio-format A map with the following keys: :sample-rate: See :sample-rates found in list-codecs. :sample-format: See :sample-formats found in list-codecs. :channel-layout: See :name of :channel-layouts found in list-codecs. "stereo" and "mono" are typical values. :codec {:id codec-id}

:video-format A map with the following keys. :pixel-format: See :pixel-formats found in list-codecs. :gop-size: optional the number of pictures in a group of pictures, or 0 for intra_only. :codec: A codec in the form, {:id codec-id}. See list-codecs.
