If both -show_{format,streams,packets,...} and -show_entries are specified, print an incompatible message. > As for what regards streams, I wonder if we should somehow support > stream specifiers, at least for what concerns options which affect a > particular stream (-show_packet, -show_streams). >=20 > A possible idea: > -select_streams v:0,a:1 > or > -select_stream v:0 -select_stream a:0 >=20 Not sure that's really necessary. I don't think a thin filtering of data belongs at ffprobe level. The user is responsible from browsing the range of results for the data he's interested in. If he is interested in one or two specific values, -show_entries looks appropriate. > or alternatively we could extend -show_entries: > -show_entries frame:v:1=3Dpts >=20 > which should be feasible assuming that sections cannot contain the ":" > character (but this really belongs to a different change/patch). >=20 > Another possible problem: if "/" is acceptable in a section name, then > I can't use it like a section/entries separator. >=20 For the syntax I don't know...
