enabling mpv prevents video playback

[ginahoy]

I just upgraded to SMPlayer v15.11 but I'm unable to figure out how to play back a YouTube video.

Having read the Oct 31 blog "How to play YouTube live streams with SMPlayer", I reinstalled SMPlayer 15.11 and selected mpv in the installer option tree. After reboot, I changed Options -> Preferences -> General from MPlayer.exe to mpv.exe, and verified that "Enable YouTube internal support" was checked @ Options -> Preferences -> Network. However, despite the blog title, there are no instructions on how to playback a live stream, just a sample YouTube URL. Hmm...

After further searching the site, I found the Nov 28 blog "Support for video sites (not only youtube)", which mentions entering the URL @ Open -> URL. Ok, fine. I tested the sample stream but I can only hear the audio. The player skin collapsed so there's no video frame. In fact, the same thing now happens when I try to play back any of my locally stored video files. I was able to restore video playback by reinstalling SMPlayer with MPlayer selected in the install options tree.

Although I'm fairly computer savvy, I know almost nothing about media players and terminology. For example, I just reviewed the MPV page (http://smplayer.sourceforge.net/mpv.php) and most of what's on that page might as well be Latin, so I apologize if I've missed something obvious.

BTW, the MPV page indicates that support for mpv is not available in the stable version. It says I need to get the current development version. I assume that information is now outdated, right? If so, should I post a separate thread about that in the Website & Forum section?

Thanks for prompt reply. The Logs -> Verbose option was already unchecked, so that's not it. I don't recall ever visiting Preferences before today, so everything should be set to "factory" except as noted in my original post.

BTW, I noticed on the Network tab, the "Enable MPV's support for streaming sites" is unchecked. I tried enabling that option but still no video. What's the purpose of that checkbox?

You didn't specify which log... this is the MPlayer/mpv log. Let me know if you need the SMPlayer log.

It's trying to use an invalid output driver (setting was carried over from having used MPlayer), in Preferences - Video, there should be a "Default" option for Output driver.

Well, that did the trick. Thanks. Now that I got it working, I have two questions...

1. Is there any disadvantage to leaving MPlayer/mpv selected @ Preferences -> General?
2. Can I save a youtube video I'm playing back on SMPlayer? (obviously not a live stream like skynews). I have an app that does that, but it would be nice if I can use SMPlayer or SMTube for that.

What's the purpose of the setting "Enable MPV's support for streaming sites" on the Network Preference menu? I'm now able to stream youtube videos and it's unchecked.

It allows to play videos from sites like DailyMotion, Vimeo, Vevo and many other sites.
