[Tizen] Stream freezes when tyring to skip ssai ad

[TomaszKowalik]

The issue is observable only on Tizen devices. In our ads, there can be a skip-ad cue point with a position that points to the ad end position. On user demand, we seek to that position. On Tizen devices, sometimes after this action the stream freezes or it does not seek to the specific position. I checked the 4.4.0-dev.2025090300 build, proposed in a different issue ticket, but the issue is still occurring. I gathered logs:

[peaBerberian]

I'm not sure I understand those logs in relation with your issue. At which point is the freeze observed?
Playback continues on those logs (after a seek at 45 - which Tizen decides to make to 43 instead because of its broken seek behavior, and then it starts back from 43).

Also it may be linked to #1736 if that's on a seek at a Period's end?

Can you re-check with our last dev version 4.4.0-dev.2025091701 (if everything goes right we may do the official release next week).

[TomaszKowalik]

Indeed, in these logs the observed issue was that Tizen seeked a few seconds back from the cue point position, so the user, instead of getting out of the advertisement, is forced to watch part of the ad anyway. Sometimes during such an action a freeze occurs, which probably depends on where the cue point is set.
We will check the suggested Rx version to see if it resolves the issue.

[peaBerberian]

Ah ok so it's not a freeze here but more a few seconds of visual glitch before restarting?

Try to see if seeking a second later fixes the issue, not that it would be the solution but just to check if it has a better result?

[TomaszKowalik]

I had to add 10 seconds, so the app was only slightly freezing but playback continued. When I was adding 3 seconds it was freezing as well. I gathered more logs:

Thanks, it is indeed freezing in that case... Exactly on Period 1_35.000000000's boundary...

We succeed to unlock the situation by performing what we call "a flush" (a small seek to 35.001 - that Tizen chose to reinterpret as 35.53) which seems to unlock the situation, but we do that a lot of time after being stuck (I guess this is just our regular heuristics that only flush when they are sure this is not just an overwhelmed device - in which case seeking would have make it worse).

To have the full picture of the situation from when we entered the seek, can you share the full log (from the loadVideo until that situation)? It may be a lot of logs, you can use gist, a file, or an other platform to share the logs.

[TomaszKowalik]

Sure, Im incluing logs from the full session:

rxTizenFreezeFullLogs.txt

[peaBerberian]

OK thanks. I looked at things like:

• codec transitions: Here it seems that the transition uses the same video codec and profile (avc1.640028)
• the audio/video segments' end from the previous Period before the transition: Here the video seems to cut nicely at 35s, the audio at 35.06, I guess we're OK
• any error or warning prior to that: there doesn't seem to be ones
• manual or browser "garbage collection": the browser just seem to consider that a segment that should have ended at 14.32 seconds actually ended at 14 seconds. This is not really notable for our problem because it's much earlier.

So sadly, everything seems to work OK from those logs ("sadly" as this is not something easy to detect there...).

Maybe Tizen has an issue especially when seeking on a transition? What happens when seeking at 35.01 instead for example?

[TomaszKowalik]

The thing is that the behavior is very inconsistent across the models, and even on the most affected model it does not happen every time. Sometimes it will seek correctly, sometimes it will freeze but recover, and other times it will experience an unrecoverable freeze and usually will crash the app. Changing the position does not seem to improve the situation. It also feels like the position from which the seek occurs matters.

I’ll gather another set of logs from one session where the stream froze and the app crashed:

[peaBerberian]

OK thanks

and the app crashed

In that case it exited the app? Like you went back on the Tizen Home screen?

When that's the case, it is generally either a relatively-legitimate memory issue (where options maxVideoBufferSize, maxBufferBehind and maxBufferAhead can help), some kind of infinite loop, or a Tizen bug.
The third possibility is the most annoying one to either get fixed or get worked around though :/

[peaBerberian]

If the log you just communicated is linked to the app crash, I would temporarily try with:

// Clean-up media data manually to ensure low memory usage
player.setMaxBufferBehind(8); // remove buffer 8 seconds behind the current playback position (enough distance to ensure it doesn't interfere with lower-level logic)
player.setMaxBufferAhead(30); // remove buffer more than 30 seconds ahead of the playback position (for e.g. when you're seeking back in time)

// Ensure the buffer we construct is lower than at least the higher limit+segment size.
player.setWantedBufferAhead(20);

Technically setMaxVideoBufferSize is the better tool but it's harder for a test as we have to check what's an actual safe limit in bytes. Checking just with values in seconds is easier for a quick test.

[TomaszKowalik]

Yes, by crash I mean returning to the Tizen home screen. It might be that adjusting these buffer settings improved the situation(really hard to say), but I can still reproduce the issue. The issue is reproducible on 2021, 2022, and 2023 models — so rather on newer ones.
The crash happens in about 1 out of 10-20 attempts; in the remaining cases, a ~2-3 second freeze is observable, but the device recovers from it.
Is there anything more that I can try out ?

[peaBerberian]

It only happens when seeking on a Period transition, like freezes?

[TomaszKowalik]

Yes, we are observing these freezes when we are "seeking out" from the commercial period to the actual content.

[peaBerberian]

Yes, we are observing these freezes when we are "seeking out" from the commercial period to the actual content.

I was referring to crashes specifically here. Freezing are sometimes seen when the device has some kind of issue with the media data and at worst can be worked around directly after the fact.
Crashes are more rare and much harder to handle...

I'll assume that Tizen here has some kind of decoding issue.
If you seek in a future period but very far (more than 30s let's say) from the transition time, does either the freezing or crash still happen?

[TomaszKowalik]

Hmm, when I'm seeking to a distant position (I set 500 seconds instead of 30), the seeking is very smooth, and there are not even short freezes.
I also observed that when I start a stream from content, then seek back to a skippable commercial, and then seek out of it (to a valid 30 second cue point), it also never crashes or freezes, and the transition is very smooth.
So it seems that this issue occurs only when the stream starts with an ad, and it seeks out to a position where periods overlap...
