Question

My version

[debug] youtube-dlc version 2020.09.16
[debug] Python version 3.8.5 (CPython) - Windows-10-10.0.19041-SP0
[debug] exe versions: ffmpeg git-2020-08-31-4a11a6f, ffprobe git-2020-08-31-4a11a6f

When I try to download this video https://www.crunchyroll.com/rezero-starting-life-in-another-world-/episode-35-i-know-hell-796213 using --hls-prefer-native this message appears 

[hlsnative] Downloading m3u8 manifest
WARNING: hlsnative has detected features it does not support, extraction will be delegated to ffmpeg

But this does not happen when using youtube-dl 2020.09.14, I always use --hls-prefer-native on Crunchyroll, because sometimes when you download using ffmpeg you get this error.

[mpegts @ 000001469b2a7800] PES packet size mismatch
[mpegts @ 000001469b2a7800] Packet corrupt (stream = 0, dts = 13684001).

And because of that the video is missing parts or skipping parts. Another question I have is that when using --hls-prefer-native, this message appears when the download is finished, but it does not happen when using --hls-prefer-ffmpeg.

[ffmpeg] Fixing malformed AAC bitstream in "Download\Re -ZERO -Starting Life in Another World- Episode 35 – I Know Hell.mp4"

This is normal?

Hm. Did you have any problems with last version (2020.09.13) or any other versions of youtube-dlc?
Also this won't appear with youtube-dl?
You could try adding --ignore-dynamic-mpd tho it is only related to dash so I don't think it would make a difference.

It just seems a strange bug to me.
Do you use any vpn? Can you provide me the m3u8 used by youtube-dlc and youtube-dl?
If it won't be displayed in console you should be able to extract it if you use --write-info-json. Search in that file for m3u8 oder manifest. Click the link and the manifest should download. You probably need to upload it somewhere or paste it into a gist/pastebin if it's not too big.

Answering your questions

  1. I have not tested other versions except the last two and the problem is present in both
  2. If you are referring to hlsnative has detected features it does not support this only happens with youtube-dlc
  3. --ignore-dynamic-mpd did not solve the problem
  4. I don't use vpn
