I think some of the x264 options changed or maybe the hq preset was wrong and has been corrected since. The ‘brdo’ option is suspect. You could try removing ‘+brdo’ from the preset file, but it would be better to use a newer version with the corresponding preset files.

I don’t think that in trunk we maintain the hq preset file anymore as we’re using files that have a better scale and correspond to presets available in the libx264 API. See my updated guide for more information.

I recommend either using the current version from your distribution or building FFmpeg from an svn checkout and updating every so often. It certainly pays to have newer x264 as well (built with asm optimisations – install yasm).

I have a somewhat generic problem (possibly specific). We are trying to roll our own encoder to encode video to H.264/mp4 so that we can stream in via RTMP. As I look around the web, I see many different recipes that seem to work, but others don’t. For example, I am getting an error with the hq recipe from above: http://ffmpeg.pastebin.com/905gUV7d

I guess the bigger question is, was there a big change from FFMpeg 0.4 to 0.5 that all these settings would change so much? Here is my FFMpeg version info: http://ffmpeg.pastebin.com/WuFct0jQ

Thanks for any help you can give me.
