how to generating thumbnail from HLS remote URL (*.m3u8) for android

Question

I am looking to generate thumbnail for particular timeframe from HLS remote URL for ex : https://devstreaming-cdn.apple.com/videos/streaming/examples/img_bipbop_adv_example_ts/master.m3u8

I have tried MediaMetadataRetriever but it does not work for live streams (HLS)

any code snippet or library is appreciated, thanks

The FFmpeg library can extract a thumbnail from a particular video frame.

Use the following function to generate a thumbnail:

private fun generateThumbnailFromHls(url: String, timestamp: String, outputImage: String) {
        val command = arrayOf(
            "-i", url,
            "-ss", timestamp,
            "-vframes", "1",
            "-q:v", "2",
            "-y", outputImage
        )

        FFmpegKit.executeAsync(command.joinToString(" ")) { session ->
            val returnCode = session.returnCode
            if (returnCode.isValueSuccess) {
                Log.d("FFmpeg", "Thumbnail saved to $outputImage")
            } else {
                Log.e("FFmpeg", "Error occurred: ${session.failStackTrace}")
            }
        }
    }

Don't forget to add FFmpeg in your app: build.gradle
