Don’t call ::output() [here: SilenceTrimmer::process()]
with no data to process.
If (position + N * period-size) % chunksize == 0;
frames_left == 0 before the last call to ::output().
chunker.h:60 keeps the ProcessContext<T>::EndOfInput
flag and the SilenceTrimmer will already have done ‘in_end’ processing.
