src = "foo.mp4"

demuxer = spdl.io.Demuxer(src)
decoder = spdl.io.Decoder(demuxer.video_codec)
for packets in demuxer.streaming_demux_video(num_frames):
    for frames in decoder.streaming_decode_packets(packets):
        # Process frames
        ...

for frames in decoder.flush():
    # Process remaining frames
    ...
