Hi list,
in our local 1.1 system we added a new workflow that creates videos in
different qualities for different internet bandwith:
http://video.virtuos.uni-osnabrueck.de:8080/engage/ui/watch.html?id=195
Change the "Quality" setting in the lower right to see the different
qualities.
We would like to too add this feature to the trunk too, but the creation
of the different qualities requires a more recent ffmpeg version that
supports the -vf (video filter) option. With -vf scale it is possible
use different resolutions for each quality and still keep the correct
aspect ratio.
I added an additonal workflow definition that encodes the video in
different qualities. If we keep our ffmpeg version these videos might
get the wrong aspect ratio if they are not in 4:3 ratio.
Any objections against an update of ffmpeg?
Rüdiger
