Audio encoding using PyMedia
Encodes raw audio data sent to its "inbox" inbox and outputs the compressed audio data from its "outbox" outbox. Decoding done using the PyMedia library.
Capturing to an MP3 file:
Pipeline( Input(44100, 2, "S16_LE"), Encoder("mp3", bitrate=128000, sample_rate=44100, channels=2) ).run()
Set up Encoder by specifying the desired compression codec and bitrate and the sample rate and number of channels of the raw audio. You may also specify other parameters specific to pymedia and the particular codec.
Send raw binary data strings containing the raw audio data to the "inbox" inbox, and raw binary data strings containing the compressed audio data will be sent out of the "outbox" outbox.
Encoder only supports a sample format of "S16_LE".
This component will terminate if a shutdownMicroprocess or producerFinished message is sent to the "control" inbox. The message will be forwarded on out of the "signal" outbox just before termination.
Encoder(codec,bitrate,sample_rate,channels,**otherparams) -> new Encoder component.
Send raw audio data to the "inbox" inbox, and compressed audio data will be sent out of the "outbox" outbox.
