So, I'm using the most recent build of Windows 10 (Build 17763) and if I don't install any codec I can't preview videos on the viewer pane at all using the movie plugin. So I tried to install FFDShow + some MPC-HC splitters like Leo suggested in the FAQ about playing videos and it didn't work. So I removed it and tried to install LAV Filters and it kinda works now, but in a really weird way.
If I just use the viewer pane, the video plays, I can hear the audio, seek, pause, change volume, but the video screen is black. If I open the video with the standalone viewer (using the >show command) the same thing happens, but the video is white. Maybe it has something to do with the colors I choose or something.
But the weirdest thing is, if I enable the viewer pane and open a video on the standalone viewer while previewing it on the pane, it works perfectly on the standalone one, while the pane is still black. Really weird.
But well, maybe i can try other plugins. So I tried to use the ActiveX one, that embeds a WMP player with autoplay, and it works perfectly for mp4 and mkv files, but most of my files are webms and it can't play them at all, even if I open it with WMP it works. Besides that the ActiveX can't zoom in, I have to change the volume for each video, it's not ideal. I tried the Windows Media Player option too, and it works with everything, mkv, mp4, flv, webm... But it does have the same problems that the ActiveX one has, and doesn't have autoplay, it just sucks.
I even reinstalled my Windows, maybe it was some weird interaction with old codecs or something funny on the registry, but it still didn't work without the LAV Filters. Already tried things suggested on Enable/fix playback of various media formats in Opus 9, but nothing worked. Now I'm with this problem, where I have 3 solutions and none of them works for me.
Any suggestion on how can I fix this? Is the video playback broken for anyone else?
