问题 I am using FLVPlayback Component in Flash AS3 to play an F4V video hosted on a different server. I want it to start playing as soon as possible, but the video won't start playing until the F4V is completely downloaded (I checked with Firebug). I tried fooling around with the component's bufferTime parameter, but it didn't seem to make a difference. For what it's worth, the SWF is being embedded in a Facebook profile using the FBML tag fb:swf , although I can't see how that would make a

问题 I am trying to implement Progressive Downloading of a video in my iOS application that can be played through AVPlayer. I have already implemented a downloader module that can download the files to the iPad. However, I have discovered I cannot play a file that is still being written to So, as far as I can tell, my only solution would be through downloading a list of file 'chunks' and then keep playing through every file as they are ready (ie: downloaded), probably using HLS Searching I have

问题 I'm working on a more secure streaming method for our video player. Because each file requires special token authentication and also only allows each token to be loaded once, I'm running MP4 through a php container. This works perfectly inside a HTML5 video tag and prevents users from easily downloading the source. I'm adapting some code from here <?php include('...'); //include site functions /* Here I connect to the database, and retrieve the location of the video which is returned as

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 9 months ago . I'm trying to implement a progressive download audio player for the iPhone, using http and fixed size mp3-files. I found the AudioStreamer project but it seems very complicated and works best with endless streams. I need to be able to find out the total length of audio files and

问题 Downloading an image from the net and showing it in an UIImageView is fairly easy. However, this requires the image to be completely downloaded before it is shown to the user, completely defeating progressive JPEG (and PNG) images. How can I render the partially downloaded images while the transfer is being done? I would imagine the SDK to have some callback function which would update the image, but I can't find such a function. Is it possible at all with the current iOS SDK? 回答1: Did you

问题 I am using AVURLAsset with various AV/MP player classes and it seems like it is ignoring my server's caching headers. I am working with small, progressively downloaded videos (not HLS). Is there a way to ensure that videos are cached? Is there a way to pre-cache videos so they play right away? I have experimented with simply changing parameters in NSURLCache, but I haven't had any luck so far. I also can't find any direct way to manipulate how URL fetches are cached by AVURLAsset. I do not

问题 In my application I need to provide the user with a preview on a progressive download (video file). In order to achieve this, I'm using VideoView component to show the content of the video (.mp4, .3gpp) which is being downloaded. The problem is that I can't access remote media via http:// or rtsp:// protocol, so I'm forced to use VideoView.setVideoPath to play local copy of the video while downloading. Unfortunately it seems like on Android devices that can't use StageFright framework (so
