Preset

class avblocks.Preset

Bases: object

Defines output presets supported by AVBlocks.

Each preset represents a collection of audio and video properties and parameters. It can be used as an easy way to specify the required output of the transcoder.

# Access presets using dot notation
preset = Preset.Video.Generic.MP4.H264_720p
print(preset)  # Output: "generic.mp4.h264.720p"

# Audio presets
audio_preset = Preset.Audio.Generic.MP3.CD
print(audio_preset)  # Output: "mp3.audiocd.192kbps"

# Device-specific presets
ipad_preset = Preset.Video.iPad.H264_720p
print(ipad_preset)  # Output: "ipad.mp4.h264.720p"

# Apple Live Streaming
streaming_preset = Preset.Video.AppleLiveStreaming.H264_720p
