Videos Enter Hyperspeed after Buffer Empties #863

Closed david-morris closed 2 years ago

david-morris commented 2 years ago

Bug report

Describe the bug

When the buffer runs empty, the video plays "catch up" and the audio skips. But that is undesirable behavior.

Expected Behavior

I would like the video and audio to resume at normal playback speed from where the buffering began.

Actual Behavior

Once buffering is completed, the video speed runs somewhere around 16x speed until caught up. Meanwhile, the audio skips ahead such that it continues smoothly with the video once caught up. This has three undesirable effects:

Possible Fix

I can see how this could be desirable for live events. But it probably shouldn't be default, and really should not be default for non-live streams. It would be nice to have this as a configurable switch.

To Reproduce

Steps to reproduce the behavior:

  1. Install kodi Youtube addon, enable inputstream adaptive for 4k 60Hz videos
  2. Throttle your internet, for example by switching to 2.4ghz wifi on a busy channel
  3. Load a big bad 4k@60Hz video that's long enough that you'll run out of buffer

i see this same behaviour on local media if it buffers over wifi. Also same behaviour when streaming content that isnt using inputstream adaptive

Therefore I dont think this is an Inputstream Adaptive issue

(You've also not supplied a full debug log)

Good point, I only noticed that after posting. Inputstream.adaptive was my only way of getting videos which used enough bandwidth to trip over their buffer for a while.

Therefore I don't think this is an Inputstream Adaptive issue

Yeah, seems like it's likely the video player itself, do you have the ability to move this issue to xbmc/xbmc or should I copy it?

You've also not supplied a full debug log

Okay. Is this a matter of logs from before the video being chosen being potentially useful, or the loglevel being too low? If it's the loglevel, since this is a transient issue, is there any way to set the loglevel without getting the debug HUD?

matthuisman commented 2 years ago

you'll need to close this issue and then create a new one on xbmc/xbmc They will require full debug logs etc

Misfiled, moving to xbmc/xbmc
