casting android screen only shows the first couple frames

[LuGia1989]

Hello developer,

I'm trying to use your codes for one of our application in which we deploy your application on an Android Virtual Machine and trying to cast any application on the Virtual Machine remotely on a remote PC.
The whole application is kind of working; however, it is casting/displaying only the first couple of frames (h264 format) on the remote PC over the tcp network, then it hang up. We have been debugging for the last couple days without any luck.
Since you are the developer of these codes, can you provide me some helpful information where I can focus and fix this issue.
Very appreciate if you could help me on this issue.

Thanks

Tom

Maybe, it's too late to reply. Did you figure it out?

I also have this problem. It shows one frame and then it stops. This is from ffmpeg/ffplay console:

I am using a Samsung S7 (with Oreo). FFLay runs on my Win10 computer. FFplay has been approved in the firewall.

Any ideas?

[moster67]

At the end it worked. I just needed to be patient. However, is it normal that it takes nearly 2 minutes (sometimes more) before screenrecording starts and being displayed by FFPlay? Once it is connected, there is very little lag except for videos.

[devggaurav]

This FFPlay is too slow at starting ,it takes ages to start, can we use something else ? or can we see casting on a particular URL in browser ?

[giegiey]

Why get this error.
