Can't play rtsp stream without sound about mdk-sdk HOT 10 CLOSED

I have no such rtsp stream. but a local video file without audio works for me.

from mdk-sdk.

I forgot to paste link to IP Webcam app: https://play.google.com/store/apps/details?id=com.pas.webcam
Maybe you have opportunity to test with it using Android phone.

from mdk-sdk.

can you send me an apk? I'm unable to install apps from google play in my country

from mdk-sdk.

Ok, I've download it from https://apkpure.com/ip-webcam/com.pas.webcam

IP Webcam_v1.14.37.759 (aarch64)_apkpure.com.zip

from mdk-sdk.

Can you try glfwplay example in the sdk? I'm failed to open the rtsp stream using mdk, ffplay and vlc.

from mdk-sdk.

Sorry, I don't have tools to build it. On my side I'm able to play rtcp stream from IP Webcam apk using vlc.

from mdk-sdk.

glfwplay is a prebuilt binary in mdk-sdk/bin

from mdk-sdk.

Ah, ok. I got the same result: it works only if sound is turned on in IP Webcam app, otherwise nothing - black screen.

from mdk-sdk.

Finally I can play the rtsp stream generated by this app. Here is the MediaInfo printed by mdk

The stream contains an invalid audio track, so video can not sync to audio. You can call player.setActiveTracks(MediaType::Audio, {}) to disable audio track, then video displays correctly.

from mdk-sdk.

fixed in the latest build
