This plugin generates thumbnail from video file or URL. It returns image in memory or writes into a file. It offers rich options to control the image format, resolution and quality. Supports iOS and Android.
This means that you will only fetch the nearest keyframe. Sure, this is super fast, but I think it should be configurable to ask for interpolated frames by using OPTION_CLOSEST instead.
I will alleviate this issue personally by forking the library, but maybe you would be so kind as to make it configurable.
I understand that making this configurable also might not make sense in a cross platform world where the iOS version might not be behaving the same way.
If I were you I would make sure iOS and android at least acted in the same way. There is no hint that copyCGImageAtTime in the iOS implementation only fetches key frames.
Hi!
I am trying to use this library to create a video timeline view with thumbnails at arbitrary millisecond intervals.
I did, however, find that you were using OPTION_CLOSEST_SYNC in the following code line:
bitmap = retriever.getScaledFrameAtTime(timeMs * 1000, MediaMetadataRetriever.OPTION_CLOSEST_SYNC, targetW, targetH);
This means that you will only fetch the nearest keyframe. Sure, this is super fast, but I think it should be configurable to ask for interpolated frames by using OPTION_CLOSEST instead.
