How do I convert an audio stream? #828
Description
Overview
Let me start off with some background. I am the author of pyWinCoreAudio
https://github.com/kdschlosser/pyWinCoreAudio/tree/develop
and I ant to be able to provide the ability for a user to play audio files so specific endpoints. This would be a useful feature to have so a user would be able to have a video playing using the default sound device and then separately have an MP3 playing to a device that is not the default.
What I need to do is have the ability to convert audio data into PCM format a that is what the IAudioClient interface in Windows needs. I want to be able to provide the ability for the users to specify a file name and the program will do the conversion of the file into PCM. I do not want a huge lag between the time the filename is specified and when the audio starts playing nor do I want to write anything to disk to achieve this. The IAudioClient interface has a buffer that needs to be filled in approximate chunks that make up one second of audio so I would like to be able to convert 1 second chinks of an input file at a time.
Is there any way to go about doing this using PyAV??
