The video is abnormal when the official linphone-android-5.2.0.apk is installed on android11 and above

Hi
@Viish
When I install the official Linphone-Android-5.2.0.APK or above on android11 and above, the mobile device cannot see the video data screen collected by linphone on PC. Similarly, I also have the same abnormal effect on MicroSIP. However, it can be obtained normally on linphone-android-5.1.4.apk. May I ask what causes this?
PC linphone verison: Desktop 5.2.1 - Qt5.15.2
Core 5.3.14
Thank you
cheers

Hi @LoyaiHai,

Please attach logs from both Android & Desktop + a video of the android app screen.

Hi
@Viish
Since I installed your APK directly, I could not find the log file in the storage of the mobile phone. Below are the versions of the PC side, the mobile phone version, and the video call screen

Hi
@Viish
here is the app log:
https://www.linphone.org:444//tmp/67063e8ed7193_e78e838d4d46eae1cbc3.gz

Given your logs video is correctly sent & received both ways.
If I were you I'd check on the FreeSwitch back to back user-agent (or try without it).

You can create two accounts for free on our service (https://subscribe.linphone.org) and make a direct call.
If issue still happens with our service please send new logs (clear old ones before).

Hi
@Viish
According to you, I registered the two account on https://subscribe.linphone.org, USES for the APK and the PC program is your official software, the results showed that both sides are no remote images

@Viish

The other problem is that at 30 seconds, it hangs up on itself

Indeed each device doesn't receive audio nor video packets.
Make sure both are configured to use stun.linphone.org STUN server & have ICE enabled.
You can also try to disable IPv6 on both device (linphone settings) just in case.

Hi
@Viish
i know ICE enabled、IPv6 enabled, but i can not find stun.linphone.org STUN server，
Could you tell me where this address is, please
Thank you
cheers

[Viish]

STUN server is a text field right above the ICE toggle.
For IPv6 disable it.

Hi
@Viish
According to what you said, I changed the configuration of the PC side and the APP side, and found that the result was the same, the remote screen was black

I have tested this problem and it is OK for versions before 5.2.110, but it will occur in versions 5.3.0 and above
