[FFmpeg-devel] [PATCH 0/3] Quram Qmage image decoder

[Peter Ross]

This patch set adds decoding support for the Quram Qmage image format,
a Korean image compressor used in Samsung phones for startup/shutdown
animations and static pictures.

Internally the image format uses RGB 565 with an optional alpha plane.
The ffmpeg decoder currently ignores the alpha plane.
