* some codecs needs additionnal format info. It is stored here
- * - encoding: set by user.
+ * if any muxer uses this then ALL demuxers/parsers AND encoders for the specific codec MUST set it correctly
+ * too otherwise stream copy breaks
+ * in general use of this field by muxers is not recommanded
+ * - encoding: set by lavc.
