Generates thumbnails, encodes HTML5-compliant videos, and embeds locally hosted videos. Requires FFMPEG or LIBAV for encoding.
Most of the time your video doesn't play because it's not encoded in the right format. Videos have containers like mp4, mov, ogv, mkv, flv, etc and within those containers there are video and audio codecs like H.264, MPEG-4, VP8, etc. The best option for this plugin is an mp4 container with H.264 video and AAC audio. mp4s with MPEG-4 video will not play in the Flash player, and if you don't use AAC audio you won't get any audio.
If you recorded the video using a Samsung Galaxy S II phone, even though most programs will tell you it's H.264 video with AAC audio, there's a good chance that it's actually recorded in 3gp4 format, which won't work with the Flash player. Use MediaInfo Library to get really detailed information about your media files.
The Strobe Media Playback Flash player will not play mp4/m4v/mov files that don't have the moov atom at the head of the file. FFMPEG puts the moov atom at the end of the file, so this can be a problem. The plugin will fix this problem on newly encoded H.264 videos if you have qt-faststart or MP4Box installed on your server.
WordPress already has a built-in system for embedding videos from YouTube, Vimeo, Dailymotion, etc. Just put the URL into your post and WordPress will automatically convert it to an embedded video using oEmbed. You don't need this plugin to do that. If you're trying to generate new thumbnails from YouTube videos, I'm not going to risk Google's wrath by providing that functionality. I'm not even sure I could figure out how to do it anyway.
If you're like most users and don't have FFMPEG installed on your server, the plugin relies on your browser's built-in ability to play videos. Google Chrome is best when making thumbnails because it supports the most formats. Wikipedia has a great chart that explains which browsers work with which video formats.
If you were able to make thumbnails using FFMPEG before updating to version 4.2, try disabling in-browser thumbnail creation in the FFMPEG Settings tab of the plugin settings.
First off, don't panic.
This plugin can use FFMPEG or LIBAV to make thumbnails and create alternate video formats. Unfortunately most servers don't have FFMPEG installed and most shared hosting plans don't allow you to install FFMPEG because of the system resources it requires. You're getting this error message because you don't have FFMPEG installed in the most common directory. If you know you have FFMPEG installed on your server, you'll need to find the actual path to the program and enter it in the plugin settings field
Path to applications on server
Enter the username & password in the plugin settings "FFMPEG Settings" tab, or use the "Embed from URL" tab and enter the URL in this format http://username:firstname.lastname@example.org/uploads/2012/01/awesomevid.mp4 in the Video URL field.
