[Mjpeg-users] Miscellaneous utilities to manipulate frame rates

2005-03-23 Thread Jerome Cornet
Hi everybody, I wrote a few simple tools to manipulate frame rates on yuv4mpeg streams. - yuvframestofields doubles the frame rate by making frames out of each field - yuvfieldstoframes halves the frame rate by making fields out of each frame - yuvntscframetopalfield takes an ntsc-rate stream

[Mjpeg-users] Smooth frame rate conversion with motion estimation

2005-03-28 Thread Jerome Cornet
As announced recently on the mjpeg-developers mailing list, I wrote a tool to convert the framerate of yuv4mpeg streams by interpolating the motion of the blocks. yuvfps can result in a jerky movement, because it duplicates or removes frames. This program, called yuvmotionfps is better if you
