:aosmond, can you comment to the bug?

It has 572 frames at 1920x1080 bytes. While each frame remains paletted, and thus 1 byte per pixel (except the first frame which is 4 bytes per pixel), it still allocates a full sized buffer for each frame. (4 * 1 + 1 * 571 * 1920 * 1080) = ~1.11 GB. We can definitely do better than this, but this is not unexpected given the current implementation.
