0002164: crf x264: no video rendered

Notes
(0006879) gmarco (reporter) 2011-06-12 20:24	it is more a libx264 thing, then kdenlive. running the command with verbose on console show the exact matter why no video is generated. i uses this too, to find out why sometimes the video is not rendered. (maybe bitrate to low, or max bitrate is needed for profile.... ) for the reason it would be good to have an debug output in kdenlive to see such messages

I think there is a problem with libraries version... Could kdenlive check the version of the libraries and warn for some incompatibility? ---- edit I've tried 0.7.8 -> failed 0.8.0 (test repo) -> it works! I'll investigate next days. I'll install again 0.8.2 (svn) and watch the errors.
