matroskademux: forward video cropping information downstream
Submitted by Fabio
MKV-file headers may contains values to be used for players affecting top-, left-, right-, and bottom-pixels cropping. Totem does not currently recognize those header values, and just ignores them.
This can be demonstrated using the mkvmerge GUI program and its header editor to fiddle with such values, and them running the resulting files through totem. Another player than totem (VLC) was tried, which recognized those values, and therefore cropped the video upon playing to remove the annoying border flickering that was experienced in that given file, without the need for the stream to be reencoded, and either suffering from a deterioration in quality, or becoming huge through lossless reencoding. (Consider this as an argument for the pertinence of this bug.)
This bug can be experienced under Precise, using the as-of-current latest build of totem.
