Hi all,
attached you can find a patch that add an option to the flags2 flag
allowing. When enabled this flag makes libav ignore the cropping
information contained in the SPS in AVC streams.

The main usecase of this feature is for stereoscopic contents: a few people
out there use the cropping information to fake a 2d signal (described
witinin the cropping region) but when 3d signalling is detected the
cropping info is discarded and the whole video surface can then be used for
3d rendering.

Note: apparently avplay crashes whenever a 1920x1088 is decoded (with or
without this patch), here is a sample

Best,
Vittorio
