Bug ID: 757022
Summary: pnm: Implementation of GRAY16 handling
Classification: Platform
Product: GStreamer
Version: git master
OS: Linux
Status: NEW
Severity: normal
Priority: Normal
Component: gst-plugins-bad
Assignee: gstreamer-bugs at lists.freedesktop.org

GNOME version: ---
The pnm encoder and decoder components do not include handling for 16Bit
grayscale images. This patch set extend the functionality of the elements,
adding GRAY16_BE and GRAY16_LE handling.
For the decoder, 16Bit images are defined when the max value of the raw pnm is
larger than 255. for BE and LE handling, the downstream peer is queried and
compatible caps are determined, prioritizing BE. The reason we prioritize BE is
because BE is the preferred format for 16bit pgm images
(http://netpbm.sourceforge.net/doc/pamendian.html).
