strict does not work with invalid stream identifiers

Description (last modified by Carl Eugen Hoyos)

Summary of the bug:
I'm trying to use the experimental branch of libvpx to test vp9, but ffmpeg won't use libvpx-vp9 even though '-strict -2' is specified. The option gets parsed but apparently not applied.
How to reproduce:

Compile the experimental branch of libvpx, enable vp9 and enable shared libraries. Compile ffmpeg with libvpx enabled. The following output is produced:

Codec AVOption strict (how strictly to follow the standards) specified for output file #0 (test2.mkv) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (test2.mkv) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
[libvpx-vp9 @ 0x169abe0] The encoder 'libvpx-vp9' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.

Please test the following:
$ ffmpeg -i input -vcodec libvpx-vp9 -strict -2 out.mkv

Summary: FFMPEG -strict -2 and -strict experimental do not get applied with vp9strict does not work with invalid stream identifiers

FFmpeg correctly prints a warning for the incorrect stream specifier, but fails then with an quite unrelated error message (that is more visible than the original warning).

Codec AVOption strict (how strictly to follow the standards) specified for output file #0 (pipe:) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (pipe:) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
[aac @ 0x21a2f20] The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.
