[BUG] Video Delay (audio plays seconds ahead of whats shown on screen), even on internal speakers. #259

Closed joshhhhyyyy closed 3 years ago

joshhhhyyyy commented 3 years ago

Describe the bug There is a noticeable video delay that gets worse the longer you play. It starts to get annoying after 5 minutes or so, as sounds of things happening in the anime do not correspond to what you see.

To Reproduce

  1. With any downloaded content (have not tried on streamed content due to long buffer times), play an anime for 5-8mins
  2. See (and hear) error

Expected behavior Audio to sync with video, as it has with previous builds. Or, for the more common occurrence of the audio being delayed.

Screenshots Not applicable.

Device:

Crash Log no crashes observed

Additional context Note that this is just to inform the developers of this persisting issue. I know that it is unlikely to be fixed as NA uses stock ios video player to play the video files.

Additional information NA is otherwise working perfectly normally on iPadOS 15.0 Developer beta, build 19A5261w, so thats great!

should add that the issue goes away after exiting playback and tapping to start playback again.

By the way you describe the issue, it seems like the issue is with the source that you are using. As you said, we use the stock video player, so I doubt it has any major syncing issues (tho, it is still possible).

May I know the source and server you used to download the videos?

PS. I'm glad the app works on iOS 15, thats nice!

i use 4anime.to ill try a difference source soon, but i tend to download a whole series before i watch it so ill report back if i find this is an issue with many sources.

the weird thing is that if i dismiss the player or force close the app then return and play the episode the delay is gone for a period of time.

i use 4anime.to

I was suspecting it was this source. Many users on our discord have reported similar problems even on the website directly.

I recommend using arrayanime as the source and see if you have any sync issues with that.

i see. thank you for notifing. the issue dosent occur when connected to airplay so thats what im doing for now. i find 4anime downloads faster and more reliable so yeah.
