In general I don't find this a very good idea. -formats/-codecs/-filters/-bsfs/... are used for *listing* elements. -help is used for showing options. If I type: -help formats I would expect the help for the formats, that is the list of *options* for the formats (this looks to me a good idea, e.g. if you just need to check options for formats, and don't care about all the other things...). Listing elements is ortoghonal to "showing options" in this sense, mixing the two is confusing. A possible implementation in that sense may be to have a -list option for listing the specified elements. _______________________________________________ libav-devel mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-devel
