Invidious now reports the actual resolution and doesn’t hardcode them anymore. See: https://github.com/iv-org/invidious/pull/4586 - Extended the list of possible resolutions in the StreamModel - trigger videoLoadFailureHandler if no streams are available - more logging for backend.bestPlayable Signed-off-by: Toni Förster <toni.foerster@gmail.com>
