[parthmshukla]

Hi,

I am getting FATAL error while recording using record() function. Below are detailed information.

• I am using javacpp-presets version 1.4.1 for Android.
• I have followed the manual approach provided in README to integrate it into an Android application.
• I can see my apk file having .so files inside lib folder.

Device : Nexus 5x Android 8.0.0.

I am continuously getting crash on record() function. Can anyone please guide me on this issue.

It just looks like you're trying to do something not supported by FFmpeg. Check what it says in its log, look for any suspicious messages, and take the appropriate actions.

BTW, to see the log, you might need to call FFmpegLogCallback.set().
