How to play rtsp H265 on Android

When I use Android Universal 1.24.4 version to play rtsp video stream, I can only play H264, but H265 cannot be played. How to solve this problem.

you need H265 codec. How do you install gstreamer in Android? Which version do you have?

Using gstreamer 1.0 android universal 1.24.5。

The player reported the following error

How do you build your app for Android? On Linux? If yes, try to run your app on Linux first and see if your code works there.

examples/tutorials/android · discontinued-for-monorepo · GStreamer / gst-docs · GitLab ,The code downloaded here,Using gstreamer 1.0 android universal 1.24.5,Playing RTSP video stream, H264 can play normally, H265 cannot play.

With 1.22.05 I do not have any problem with H265 in rtsp streaming on Ubuntu. But I have not tried 1.24.5.

What commands need to be entered on Ubuntu

Try playbin3 to decode rtsp streaming. Playbin is old.
gst-launch-1.0 playbin3 uri=rtsp://your_rtsp_stream_url
