Is it possible to get the resolution of a video in Android?

You can use the MediaMetadataRetriever to retrieve resolution information about a video file. You'd use the extractMetadata() method and using the METADATA_KEY_VIDEO_HEIGHT and METADATA_KEY_VIDEO_WIDTH constants. So you'd do something like this:

MediaMetadataRetriever metaRetriever = new MediaMetadataRetriever();
metaRetriever.setDataSource(/* file descriptor or file path goes here */);
String height = metaRetriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_HEIGHT);
String width = metaRetriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_WIDTH);

Kotlin Extension Solution

Here is the way to fetch media file dimensions in Kotlin

val (width, height) = myFile.getMediaDimensions(context)

fun File.getMediaDimensions(context: Context): Pair<Int, Int>? {
    if (!exists()) return null
    val retriever = MediaMetadataRetriever()
    retriever.setDataSource(context, Uri.parse(absolutePath))

    val width = retriever.extractMetadata(METADATA_KEY_VIDEO_WIDTH).toIntOrNull() ?: return null
    val height = retriever.extractMetadata(METADATA_KEY_VIDEO_HEIGHT).toIntOrNull() ?: return null

    retriever.release()
    return Pair(width, height)
}

If you want to make it safer (Uri.parse could throw exception), use this combination. The others are generally just useful as well :)

fun String?.asUri(): Uri? {
    try {
        return Uri.parse(this)
    } catch (e: Exception) {
    }
    return null
}

val File.uri get() = absolutePath.asUri()

fun File.getMediaDimensions(context: Context): Pair<Int, Int>? {
    if (!exists()) return 0
    val retriever = MediaMetadataRetriever()
    retriever.setDataSource(context, uri)

    val width = retriever.extractMetadata(METADATA_KEY_VIDEO_WIDTH).toIntOrNull() ?: return null
    val height = retriever.extractMetadata(METADATA_KEY_VIDEO_HEIGHT).toIntOrNull() ?: return null

    retriever.release()
    return Pair(width, height)
}

Not necessary here, but generally helpful additional Uri extensions

val Uri?.exists get() = if (this == null) false else asFile().exists()

fun Uri.asFile(): File = File(toString())

Trick for API 10+:

MediaMetadataRetriever mRetriever = new MediaMetadataRetriever();
mRetriever.setDataSource("video_file_path");
Bitmap frame = mRetriever.getFrameAtTime();

int width = frame.getWidth();
int height = frame.getHeight();

We are simple taking a random frame from our video and detecting its width and height.

If you have Video Content URI then you can also use content provider query

Like

    Cursor mediaCursor = getContentResolver().query(
                        videoContentURI,
                        {MediaStore.Video.Media.RESOLUTION}, null, null, null);
        if (mediaCursor != null) {
                    if (mediaCursor.moveToFirst()) {
        //The resolution of the video file, formatted as "XxY"
        String resolution=mediaCursor.getString(mediaCursor
                                  .getColumnIndex(MediaStore.Video.Media.RESOLUTION));
    }
}
