flv

问题 First of all, the "properly" in the title refers to this related question, of which answer does not solve my problem. tl;dr: There is a difference between encoding a video and directly storing it into FLV and doing this in two separate steps. I need to do it separately, how do I get the same result as doing it directly? Nvidia's hardware encoder NVENC produces raw H.264 data without a container, which is difficult to play in most video players. For an Adobe AIR application, I need to wrap the

问题 I will need to display the frames of an FLV at different rates. Here are some examples: the user will 'scrub' through the flv frames(front/back) the flv will need to play at half the speed on a user interaction. Currently I'm using LoaderMax and it's VideoLoader object to load and play FLV files. I've tried using the playProgress property, but only the keyframes of the FLV are displayed. I got the same result with the basic setup(using the NetStream class) As a workaround, I playback the FLV

问题 What I want is straightforward: wrap H.264 video stream into a FLV container. However, ffmpeg just decode the input stream and pack raw video stream into FLV. The details are described below: The input stream is captured from a hardware-encoder video camera, and the FLV will be sent to some video server. Firstly I used following command: $ ffmpeg -framerate 15 -s 320x240 -i /dev/video1 -f flv "rtmp://some.website.com/receive/path" However, the resultant stream is suspicious. The watching side

问题 I am trying to convert a mov video to flv using vp6 encoding. I tried the following: ffmpeg -i video.mov video.flv However, it uses the flv1 codec. I need this kind of encoding (Oracle's "oow2010-2.flv" video), which I think uses vp6 or vp6f codec. I searched and it seems people only do decoding from flv/vp6. By the way, I can't use H.264, it has to be vp6. 来源： https://stackoverflow.com/questions/43382513/convert-to-flv-with-vp6-encoding-using-ffmpeg

问题 For the last 4 hours I've been trying to combine 2 .flv files into one using ffmpeg (or well, just C# in general). Here's what I got so far: I've converted both the videos to .mp4 videos: "-i " + videoFileLocation + " -c copy -copyts " + newConvertedFileLocation I have then combined the two .mp4 files into a single one using: (txtPath is the text file with the two mp4 file locations) "-f concat -i " + txtPath + " -c copy " + saveLocation This ends up with an mp4 file which contains the

问题 I'm using the following code to reuse a single FLVPlayback component variable. Would anyone know why the NetStream doesn't stop? public function clearVideoPlayer(newSource:String):void { if (_videoFLV) { removeChild(_videoFLV); _videoFLV.getVideoPlayer(0).close(); _videoFLV = null; } _videoFLV = new FLVPlayback(); _videoFLV.autoPlay = false; _videoFLV.autoRewind = false; _videoFLV.width = 320; _videoFLV.height = 240; _videoFLV.source = newSource; addChild(_videoFLV); } But after running the

问题 I am trying to create a simple app for the iPad that with play an FLV when you click a button. I am using the code from http://developer.apple.com/iphone/library/codinghowtos/AudioAndVideo/index.html#VIDEO-USE_THE_MEDIA_PLAYER_FRAMEWORK_FOR_VIDEO_PLAYBACK as a reference. Here is the code for my click event -(IBAction) btnPlayVideoClick:(id) sender { NSString* videoPath = [[NSBundle mainBundle] pathForResource:@"myVideo" ofType:@"flv"]; MPMoviePlayerController* myMovie = [

问题 I am trying to embed a flash movie (.flv) into a webpage with a transparent background. Requirements: - Flv runs in transparent mode - I must be able to view html contents below. - Movie does not auto play - Movie is contained in a div and positionend absolutely using CSS - No video controls or overlays, you shouldn't know it's an flv - On load Movie is hidden - Using jQuery, I click an image link to show and play the video, clicking it again stops and hides the video - vice versa I have

问题 Is it possible to set the frame count of a video manually in Flash BUilder 4? How is the frame length of a video determined in Flash Builder 4? I need to do this in order to trick video format converters into thinking that my video is actually x frames long instead of just 1 (my swf video is controlled completely through as3 code and thus resided on just the 1st frame). This way, the video format converters will be able to automatically (and correctly) convert my videos to another format (flv

问题 This question already has an answer here : FFmpeg converting image sequence to video results in blank video [closed] (1 answer) Closed 2 years ago . My current project involves creating a .flv using AIR (using https://github.com/zeropointnine/leelib/tree/master/src/leelib/util/flvEncoder) - which then has to be converted into an .mp4, for which we are using ffmpeg. The .mp4 output is the correct dimensions and duration, but blank (no images). Audio is not an issue as the original output has
