Thanks for your comments. It's hard for me to stress the point of the approach further. I wonder if it becomes clearer if we use TEXT1="one" TEXT2="two" X2=100 in discussed scripts. Maybe a paragraph describing the flaw of naive approach should be added to example annotation itself? I just followed the present pattern, that example description is very concise. ________________________________ _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
