flv

问题 I am trying write a real-time flv stream demuxer on windows-runtime, for win8.1 and wp8.1's MediaElement. I've already finish the demux code, flv files can be correctly demuxed into h264 and aac tag-datas. When I was trying to play network files and streams, I got a very strange network problem: The same code, run under win8.1, all good, whatever files or network streams (proves demux code is ok); run under wp8.1 (real phone or emulator), files are good, network streams are bad - no matter

问题 While i try to get length of a flv video file i get 0 second where as it only happens with some videos, else my function works fine. below is my code. <?php function mbmGetFLVDuration($file){ // read file if (file_exists($file)){ $handle = fopen($file, "r"); $contents = fread($handle, filesize($file)); fclose($handle); // if (strlen($contents) > 3){ if (substr($contents,0,3) == "FLV"){ $taglen = hexdec(bin2hex(substr($contents,strlen($contents)-3))); if (strlen($contents) > $taglen){

问题 Hey I know this question is too old and repetitive but keeping in account of the changing nature of the youtube API and its various representational structure I would like to pose this question once more. How can I get .flv url of the video of the youtube. Please suggest me links or ways or code (java python c preferred). Thankyou 回答1: The get_video_info page is interesting. However consider the following script function urldecode { awk -niord '{printf RT ? $0 chr("0x" substr(RT,2)) : $0}' RS

问题 I'm trying to have a jsfl script import a video into my .fla project and export the entire thing as a .swf automatically Is it possible to disable the video wizard when importing videos? I'd hate to have to manually confirm all the options every single time. The video is in .flv format if that makes any difference 回答1: AFAIK you can't bypass the FLV import dialog directly (using the JSFL API). I've tried automating the FLV import wizard using a Sikuli script. The script can be run from JSFL

问题 I want to play the flv files in Android. So what I thought is to convert the flv file to mp4 or 3gp(for which there is a decoder in Android). OpenCore can be used to convert. I have looked into opencore code, there is a class in opencore "/android/external/opencore/fileformats/mp4/composer" to create the mp4 file. It has apis like AddTrack AddSampleToTrack I should give the input as frames, but in Flv I will get the Sorenson Video and Mp3 audio frame(after doing some trivial string operations

问题 I'm looking for an example of parsing an FLV header for duration specifically in Java. Given the URL of an FLV file I want to download the header only and parse out the duration. I have the FLV spec but I want an example. Python or PHP would be OK too but Java is preferred. 回答1: Do you have problems downloading the header or parsing it? if it's downloading then use this code: URL url = new URL(fileUrl); InputStream dis = url.openStream(); byte[] header = new byte[HEADER_SIZE]; dis.read(header

问题 I have created a video player, but need to add a button that, when clicked, puts the video into full-screen viewing mode. I don't want to scale everything on the stage - just the video. I can't seem to find how to do this - I thought it would be easy. 回答1: See if this works: stage.displayState = StageDisplayState.FULL_SCREEN; videoPlayer.x = 0; videoPlayer.y = 0; //save the width and height in temp vars //for restoring them later. videoPlayer.width = stage.fullScreenWidth; videoPlayer.height

问题 does anybody know how to convert any kind of video format into flv using java, i have been searching for a java api for converting video but it seems that there is no such thing but there might be a way to do it, i mean to make something like youtube service does converting the videos, but using java, i need a web application that can show videos into FLv Format but to be uploaded in any format, if somebody has made something like this please let me know how or any idea, thanks. 回答1: None in
