Avi Halachmi (:avih) 836e87e6d4 hwdec: warn on unsupported hwdec option value ... Previously, when mpv was invoked with unsupported hwdec value, such as --hwdec=foobar, there was no indication that it doesn't exist. The reason it's not validated during options parsing is that the name is only evaluated when selecting hwdec for actual decoding, by matching it against runtime list of names from ffmpeg. Additionally, when selecting hwdec for decoding, matching the name came after filtering by codec, hence overall never-matched-name did not necessarily indicate it's unsupported (doesn't exist at all). Now we check the name before filtering by codec, and when done, warn if no hwdec with that name exists at all. This means that an unsupported name will now generate such warning whenever we try to choose a hwdec, i.e. possibly more than once. It's much better than no notification at all, and arguably adequate for a sort of configuration error (linked ffmpeg has no such hwdec name) which we don't validate during option parsing.		2022-03-07 01:05:20 +02:00
