Got it working with all pix_fmts and drivers. Am attaching the tar.gz file containing all the patches to be applied as specified in the series file. Cinelerra seems to use packed formats whereas ffmpeg has moved to providing planar formats for almost everything - upto eight planes. Tested RGB, RGBA FLOAT RGB FLOAT RGBA YUV YUVA formats in X11, Xv and openGL. Playback of .MTS files OK. Rendering thro' YUV4MPEG pipe to dnxhd at 365000000 bps using ffmpeg OK - whew! Would be nice to extend to write next. But only after taking off to shoot and edit-:) Arvind
