Shaka hangs when fast forwarding or rewinding on tv

[FiberOnePL]

After recent changes on the TV on which Shaka was working correctly, scrolling no longer works, after selecting a new position on the bar, buffering starts and nothing happens.

After a longer analysis I noticed that 80% of attempts to rewind the movie using the progress bar end with buffering and freezing the playback, another 15% end with the movie playing but without audio and 5% are successful attempts. Tested on Samsung TV.

Can you reproduce it in any other platform?

[FiberOnePL]

@avelad It definitely doesn't work on Samsung, I checked it on 2 other TVs, on my old Sony it seems to work fine

[avelad]

Are you using DASH or HLS?

[FiberOnePL]

Dash.

VIDAA, WebOS TV, TITAN OS Everything works properly, no stuttering. The problem occurs on Samsung, where the problem did not occur before.

[avelad]

Can you change the value of shaka.util.Platform.isSeekingSlow to return true for the models that fail (Tizen) and tell me if that fixes the problem? if that fixes it I can add this change to the code base.

Closing due to inactivity. If this is still an issue for you or if you have further questions, the OP can ask shaka-bot to reopen it by including @shaka-bot reopen in a comment.

@avelad The problem persists. After moving the bar to a new location it freezes and does not play from the new location.

Watch the video I recorded, maybe it will tell you what the problem is. It only happens on Samsung.

Your suggestion that you gave was added the message is true however it did not fix the problem.

From what I see issue appears only when cursor is used with a seekbar. Unfortunately, it's not possible (or I don't know a way) to enable cursor in Tizen app, so it's issue browser specific. Behavior is correct when clicking left/right arrow.

[FiberOnePL]

@tykus160 The browser is ok and was working properly, recent changes in shaka player caused this problem.

[avelad]

@FiberOnePL Are you using Shaka UI? Are you using the browser of the TV or a Tizen app?

[FiberOnePL]

@avelad Shaka UI and browser everything was working properly before, recent changes broke something.

@avelad I checked on the demo shaka the problem is the same, however I noticed that if I select a new position on the bar which is marked as buffered the problem does not occur and the video works correctly if I select in a place that is not buffered then the playback freezes in the new place. Maybe this will help in solving the problem.
