flv

问题 I'm looking for a solution for embedding video and audio in html. The new videotag supports .ogg and .mp4, but is there a fallback solution for .flv and other formats? For example, if I want to embed an .ogg, it will check whether or not html5 is supported, if not, it uses the fallback. If I want to embed a .flv is uses the fallback. 回答1: html5 tag supports a fallback to any element, if the browser cannot interpret the video tag. here s a quick example for a fallback to a flash-file. <video

问题 I'm looking for a way to extract the audio part of a FLV file. I'm recording from the user's microphone and the audio is encoded using the Nellymoser Asao Codec.

问题 And save it as an image. Is this kind of job possible in PHP? 回答1: PHP has an ffmpeg library which you can use for this. Utilizing ffmpeg_movie you can return a video file as an object: $movie = new ffmpeg_movie('/path/to/.flv'); You can then go on and use the getFrame() method, which returns the frame as an ffmpeg_frame object, which has the method toGDImage() which returns a GD image of the frame. Obviously the GD library needs to be enabled. 回答2: See this question. All the solutions seem

问题 I have a PHP file that generates a Media RSS file for the embedded wall. It reads images and video from our Amazon S3 bucket and signs the URLs before creating the RSS feed. When the wall loads, images display perfectly. Where there should be video there is only an empty black square, when the video is clicked - still only an empty square.

问题 I have a flv file inside the vid.html which is working fine, but is there any way to have the video itself to fadeIn/fadeOut? <div id="fadeit"> <div class="video"></div> </div> this does not work; $('.video').hide().fadeIn().load('vid.html'); wrapping it in a div and fading the div does not work either; $('#fadeit').hide().fadeIn(1400); 回答1: no wmode or wmode transparent: FF, Chrome and Safari wmode opaque, FF, Chrome, Safari and IE8 (only have ie8 to test) Both fade flash and div overlay.

问题 What possibilities are there for inserting and showing videos on a webpage that don't require additional plugins or installations from the user and can be used for other than the .flv format (.f4v, .avi e.g.) At SO I found a few questions like this: stackoverflow.com[...], but they are only about .flv-players.
