[gst-devel] gstmediaplay and a project of the week for someone

[Dan Dennedy]

The inability to make screenshots of the video with Xv output is due to 
something very fundamental in the nature of Xv. I think attempting to 
workaround this issue by automatically, repeatedly switching on and off 
Xv would lead to performance and stability issues, especially when 
seeking. Not only is it potentially unstable within XFree86 and XVideo 
itself, but it also over-complicates the integration within 
gstmediaplay. Instead, I propose that this issue be resolved by allowing 
the user to manually disable Xv within gstmediaplay and through 
education (FAQ item). When the user chooses to disable Xv output through 
a preferences item, simply modify the pipeline.
