[Mjpeg-users] exchanging fields

[freeze <fr...@my...>]

When I use "lav2yuv -x | yuv2lav -fa -owhatever.avi" to swap the fields on some previously captured MJPEG avi's Mainactor fails to recognize the clip as an MJPEG avi, yet the field-swapped clip outputs fine with lavplay.  Is there any way to make the clip parsable by Mainactor or another way to swap fields in previously captured clips?

thanks,
Matt Meno

PS: I'm using the 1.5 CVS mjpegtools, latest CVS zoran driver (with LML33) and kernel 2.4.3.
