* rearrange methods following the flow * add test_stream_helper.py * fix lint * fix lint * refactor audio flow to match video by replacing dequeue with queue * remove unused keyframe interval * remove try block * remove while True * simplify run_aom_encode_loop and run_vp8_encode_loop * cleanup names * simplify run_opus_encode_loop * move opus_encoder creation to run_opus_encode_loop * add todos * fix lint * update todos and tests
