Audio stutter android 8.0

Rodp

Hi All,

Have recently setup a reolink doorbell but am finding the audio is stuttering. Support have not been able to solve it so far so it invariably means i cannot use the live stream to listen to the visitor when they ring the doorbell. When i talk back to them the audio at the door bell end is fine. These are the things i've tried all to no effect.

App hardware video off and auto scaling, clear or fluent mode, going back to an older app version, wired connection instead of wifi, different device (huawei media tab 2), adjusted volume, uninstall numerous apps including reolink app and reinstalled.

On the app the audio when turned on is fine for about 1 second and then starts to stutter. The video doesn't seem to be impacted and remains smooth. Playing h.264 high bit rate mp4 files is fine on my phone.

I have tried the http access via a chrome browser on my phone and that interestingly is absolutely fine. No stutter. But the problem is there is no two way talk.

Does anyone have any suggestions in fixing this stuttering or knows how to enable two way talk via the browser?

Thanks in advance

Hi All,

I have an update... By reducing the frame rate (via the web user interface of the camera) from a default of 20 for clear and 15 for fluent down to 4 or 6 respectively, the audio no longer stutters, so that's great new, however this is detrimental to the video frame rate that you view on the phone but at least you can actually now here the person speak clearly now. Would this setting also stop full 20fps or 15frps recording on an NVR if I was to buy one?

On a technical front, changing the FPS will amend the encoding process on the camera I suspect. Some other devices (i've borrowed) have been fine at higher frame rates - even at the max) so do you think this might mean a problem with the encoding (ie camera firmware) or decoding (a combination of the phone and app)?

Changing the birate has no effect it seems, changing to the lowest quality or leaving it on the highest settings makes no difference. However, disabling the hardware decoder setting on the App on my phone does cause the audio to stutter again, even at the lowest frame rates.

Please could someone advice what this might mean (as technical as you like as I will plan to forward this to the engineers in hope that can make a change).

Thanks

Key points: (unable to paste images in!)
Fluent mode: On the web user interface, by increasing the Frame Rate setting from either 4 or 7 to 10 or 15, the audio starts to stutter on the phone app.
Clear mode: When I am using the App on High / Clear mode, reducing the FPS from 20 down to 6fps or lower stops the audio from stuttering.
Disabling the hardware decoder setting causes stuttering to occur again, even at these low FPS settings, on both Clear and Fluent modes.

Phone in use, Android 8.0, Samsung A5 2017

Some pics (wouldn't let me include them in the previous reply! I think it didn't like inline images rather than inserting from a file and now it's told me I have to wait 600 seconds and now 1800 seconds before adding another post as I don't have enough reputation points! )

These settings stopped the phone stuttering at the expense of recording frame rate which i fear may also impact the NVR - can anyone confirm that ?

Thanks
