Is it allowed to stick a file like "readme-extra-plugins.txt" in the recipes-multimedia/gstreamer/ directory? Because then, questions about performance,orc,yasm can be answered by pointing to that file. At least there would be a documentation.. In addition, regarding orc and yasm, it would help to print out a warning about the performance, briefly describing the situation (yasm and orc missing), and a link to the documentation with details. carlos
