The same glitches happens with our stream so we checked the streams in the Demo App and they have the same issue.

Opened internal tracker 333604485. Checking to see if we have these devices and can reproduce.

We found more devices got issue:
Samsung Galaxy A42 5G, A41, Z Fold4, Tab A, A12, A21s, Huawei Mate 10 pro, P20 Pro, P40 pro. Oppo CPH 2185, Lenovo Tab M10 FHD plus.
Thanks.

It's more obvious by playing the 60 fps WV encrypted stream on the Demo App:
{
"name": "HD (MP4, H264, Widevine cenc)",
"uri": "https://storage.googleapis.com/exoplayer-test-media-1/60fps/bbb-wv-1080/manifest.mpd",
"drm_scheme": "widevine",
"drm_license_uri": "https://proxy.uat.widevine.com/proxy?provider=widevine_test"
},
almost half of the frames dropped.
Thanks

Are you seeing the problem with newer launches from these same manufacturers? For example we are able to reproduce on a Galaxy A50 but not on a A03 running android 13

We've seen this on Android 10, 11 and 13, so not sure if it's related with newer version or not. With same manufacturer, like Samsung, yes, it's very random for the model which is ok or non-ok.
Did you see any clues in Galaxy A50 which can reproduce the issue? From the log we can only see there are frame drops but don't know why it happens.

Can you let us know which devices are running Android 13 that exhibit this issue

Hi @rrfrias , we found several Android 13 devices may have the issue as it's reported from our end user:
Nokia X30 5G, POCO M3 Pro 5G, Redmi Note 12 Pro 5G, Samsung Galaxy A12.
Thanks

Thanks! Opened tracker for to follow up with Samsung (internal ref: 340937658]

Hi @rrfrias , any news for this? More of our customers complain the video quality on their device.
Many thanks.

We are waiting on Samsung to reproduce and get back to us.

Thanks @rrfrias , may I ask if there is any feedback ? and if not would you mind to have a estimate date please?
Best Regard.

On our latest investigation, if we set the WV security level to L3, it seems resolving on most of the devices, but not all. we can't adapt this solution now but hope this helps the debugging.

Thanks for this information. Trying to get Samsung's attention.

Thanks @rrfrias. Would be great appreciated if you can bring this to Widevine also.

Samsung was able to reproduce the issue. Our contacts have passed it to an internal team that are investigating. Will update when we know more.

We are still working with Samsung to investigate this issue.
