".psd", "psd", "Psd", "Photoshop file". I think some consistency would
be nice. E.g. use "Photoshop PSD file" as long name, "PSD" in the
descriptions (and not the name of the extension with dot).

But that's just cosmetics...

You could leave whitespace around the operators, for readability.

For the sake of "grammar", I would say:
                avpriv_report_missing_feature(avctx, "channel depth %d 
unsupported for rgb", s->channel_depth);
(Same with channel_count and with grayscale below.)

Whitespace, as mentioned above.
