Tell the stream that you're done sending data, and anything being buffered should be converted/resampled and made available immediately.
int SDL_FlushAudioStream(SDL_AudioStream *stream);
|stream||The audio stream to flush|
Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
It is legal to add more data to a stream after flushing, but there will be audio gaps in the output. Generally this is intended to signal the end of input, so the complete output becomes available.
It is safe to call this function from any thread.
This function is available since SDL 3.0.0.
