Is it possible to Generate a thumbnail from a video url in android

Question

I am working on a video app. I am streaming a video from server link , is it possible for me to generate a video thumbnail from the URL without downloading the video.

Answer 1

Without downloading video you can generate thumbnail from below code:

public static Bitmap retriveVideoFrameFromVideo(String videoPath) throws Throwable {     Bitmap bitmap = null;     MediaMetadataRetriever mediaMetadataRetriever = null;     try     {         mediaMetadataRetriever = new MediaMetadataRetriever();         if (Build.VERSION.SDK_INT >= 14)             mediaMetadataRetriever.setDataSource(videoPath, new HashMap<String, String>());         else             mediaMetadataRetriever.setDataSource(videoPath);    //   mediaMetadataRetriever.setDataSource(videoPath);         bitmap = mediaMetadataRetriever.getFrameAtTime();     } catch (Exception e) {         e.printStackTrace();         throw new Throwable("Exception in retriveVideoFrameFromVideo(String videoPath)" + e.getMessage());      } finally {         if (mediaMetadataRetriever != null) {             mediaMetadataRetriever.release();         }     }     return bitmap; } 

NOTE : Video is stored as Intra and non Intra (Picture frames) getFrameAtTime will return the closest non- Intra frame as Bitmap. So basically it won't download the entire video.

Answer 2

I tried this with glide and it worked , Glide version 4.3.1

    GlideApp.with(context)                 .asBitmap()                 .load(FILE_URL)                 .diskCacheStrategy(DiskCacheStrategy.DATA)                 .into(iv_picture); 

Edit : Glide was working slow for me

The Top answer was not giving result for some videos , here is how i did it

MediaMetadataRetriever retriever = new MediaMetadataRetriever();  //give YourVideoUrl below retriever.setDataSource("YourVideoUrl", new HashMap<String, String>()); // this gets frame at 2nd second Bitmap image = retriever.getFrameAtTime(2000000, MediaMetadataRetriever.OPTION_CLOSEST_SYNC);  //use this bitmap image
