It works for me in ffplay, inigo, and kdenlive using the same source file canon-hf-100-1080p-psf.mts and converted in the same manner. I originally developed and tested this dnxhd conversion routine using some other AVCHD on my Ubuntu 9.04 system at work. Then, I tried with this canon hf100 sample at home using my Arch Linux workstation. Both worked fine and with different versions of ffmpeg on each. I am using FFmpeg SVN-r17923 on my Arch Linux box. -- +-DRD-+ ------------------------------------------------------------------------------ Register Now & Save for Velocity, the Web Performance & Operations Conference from O'Reilly Media.
