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 (at 29.97fps) and makes it a pal-field-rate stream (at 50fps); this is done by replicating select frames. The first two are very similar to the cinelerra plugins "Fields to Frames" and "Frames to Fields", hence the names You can find them at: http://jcornet.free.fr/linux/mjpegtools.html They are still rough (you cannot select which field goes first, for now it's always the bottom), but still quite useable (I haven't dount too many bugs yet !). Don't hesitate to send comments or patches ;-) Have fun, /Jerome
