Approximate mode fails on video #677
Description
Using Using huggingface.co/datasets/raushan-testing-hf/videos-test/blob/main/sample_video_2.avi, same as in #676
decoding frames (by indices) works on exact mode, but not with approximate mode. (Ironically, it's the opposite for .metadata access as described in #676
Not sure what might be the cause yet, probably related to how we handle metadata. Maybe this isn't a bug and something expected due to how approximate mode is implemented (regardless, we should fix #676)
