avdec_h264 is a software decoder. A Pi0 is likely to struggle doing H264 decode even at 640x360, particularly when combined with a videoconvert (software conversion) and autovideosink (probably another software conversion).
v4l2_h264dec should give you hardware decoding. If you're booting to a console only (not desktop), then using kmssink should be the most efficient renderer, and there shouldn't be the need for any conversion between the two.
