I have a file containing serialized objects containing a byte representing a JPEG image.
What I need to do is read through the file via ObjectInputStream to deserialize the object so that I can get the byte and then convert it to BufferedImage.
The reason for doing this is due to the fact the a BufferedImage is not serializable so the JPEG image is serialized as byte.
The reason for serializing the JPEG images into objects via OjectOutputStream is so that I can store some metadata for a particular frame and then display it as I am playing the sequence of images. (movie)
The issue is converting a byte to BufferedImage costs time to process. For example: a 5000 by 5000 JPG image in byte to BufferedImage takes 0.3 seconds. This will results in a 2 frame by second play back. if I want to play it as 10 frames per second, I would need to get the byte to BufferedImage conversion down to at a minimum 0.1 seconds.
If I was to process this at first or through some Thread, then I would need to store all of these processed images (BufferedImage) into memory. This would result in a JVM memory leak (OutOfMemory).
The next option where I am stuck on is caching these BufferedImages. (approx 50,000 frames at 200k per frames)
Is the a optimal caching soltion of these BufferedImages or is there a more optimal approach to serializing an object containing memtadata and byte (JPG image) and then streaming then as we read the file with a byte to BufferedImage conversion?
