1920x1440 or higher video couldn't play on Samsung devices, indicating that the file type is not supported

[s2g090123]

I am trying to create video via FFmpegFrameRecorder. The video size is 1920x1440 but it doesn't play on Samsung devices. The file type is not supported. I have tried 1920x1080 and 1024x768, both work. Or what codec should I set?

Below is my sample code

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        create()
    }

    private fun create() {
        val file = File(getExternalFilesDir("video"), "test.mp4")
        if (file.exists()) {
            file.delete()
        }
        val recorder = FFmpegFrameRecorder(file, 1920, 1440)
        recorder.format = "mp4"
        val converter = AndroidFrameConverter()
        val bitmap = Bitmap.createBitmap(1920, 1440, Bitmap.Config.ARGB_8888)
        recorder.start()
        recorder.record(converter.convert(bitmap))
        converter.close()
        recorder.stop()
        recorder.release()
    }
}

Thank you so much!

You may want to try to use the "main" profile instead of "baseline" as pointed out by @vonabe at issue https://github.com/bytedeco/javacv/issues/1885#issuecomment-1241019473.

Sorry, I didn't understand what you said.

Replace FF_PROFILE_H264_CONSTRAINED_BASELINE with FF_PROFILE_H264_MAIN in video_c.profile(AVCodecContext.FF_PROFILE_H264_CONSTRAINED_BASELINE)?

Actually, there is no need to add anything to JavaCV to get this working. I've confirmed that, for example, calling setVideoOption("profile", "main") before start() does set the profile to "main", see https://trac.ffmpeg.org/wiki/Encode/H.264#Profile.
