I am trying to play uncompressed rgb QHD material with mplayer. After
modifying transcode to handle QHD, I was able to generate an .avi from
the .png frames of the video. I can play them with mplayer using
"-vo x11" but only at about 14fps. I need to play at 24fps.
When I use the xv output driver, I get the Transcript below. Is it
straightforward to increase the accepted dimensions of the xv output
driver in the mplayer source code?
The transcode people were kind enough to help me do something similar
with `transcode'. It turned out to be a change in a #define and a
I'm hoping one of the helpful gurus on this list can provide a solution.
