I have used the following properties in the meta data handler for finding the keyframes, but returned nothing:
var kfPoints:Object;
for (var propName:String in metaInfoObj)
{
if (propName == "keyframes")

How can I find keyframes in an mp4 file transcoded with an H264 codec?
I'm trying to publish video streaming over internet. I want to use the h264 codec in FMS for that. Is there any in built property or setting to use h264 or have to use library for that. And also want to know among VP6, sorenson and 264 which is better to use.
View 6 RepliesRight now I am working on an AIR 3.2 application which lets you stream a video to a Flash Media Server and saves it on a hard drive.This sequence works fine with the standard Sorenson codec but I want to use H.264 for my videos. I found lots example c ode and implemented it in my code, but when I record a video of myself I am unable to re-watch it afterwards.I found how to implement a H.264 encoding in a realeyes blog post here. My code is here.It saves the video as a .f4v file, but my browser (I've tried the latest versions of both Chrome and Firefox, with the latest Flash) and also VLC are unable to load the video. I also used a program called Movie Player which is able to open the file but can only show the first frame and the audio. Neither am I able to upload the video to YouTube because they do not support the file extension.Here is an example video file it saved: H264Test1.f4v.My question is: How do I stream and save the movie with a file extension that I am able to re-watch while using the H.264 codec?
View 1 RepliesI've been sent a link to an FLV file that plays in the browser and when downloaded plays in Adobe Media Player.
However, when I try to import it into Flash, I get the error message
unsupported audio codec
It'll bring in the video no problem.
I've tried to use Adobe Media Encoder to convert the file but it doesn't see the audio either.
Is this some kind of protection on the audio? What am I missing?
I want to be able to stream a live video using Flash Media Live Encoder 3 using two options of 300 kbps and 150 kbps.I want to give users a choice of stream quality depending on their available bandwidth to maintain the live feed.I have set it up so that the Bit Rates are 300 and 150 and tick marks on: 1 and 2my FMS URL is correctin the Stream: box I have written: test1;test2The SMIL file has the following:
<smil> <head> <meta base="rtmp://live" /> <body> <switch>
<video src="mp4:test1.f4v" system-bitrate="150000"/>

I am working freelance on an animated show for children, animating characters in flash, and I have a problem that is driving me crazy.
I will try to explain it so it won't be too confusing. This just happened on the file I am working on now, an animation of a character walking: The graphic symbol containing the legs had two keyframes in it (on frame 1 and 2) when I saved the file. When I reopened it, the legs had only keyframes on frame 1. When I check the swf I exported just before saving, the legs are fine.
Similar problems has happened many times now, sometimes keyframes are gone, other times they have turned blank, and on one occation graphic symbols had changed to empty movie clip symbols. The last swf exported has always been okay.

I'm trying to play a 10 minute long video (h264/mp4) which is 39MB in size, after I call stream.play(fileURL) it doesn't start playback until its loaded around 12-16MB of the file (many many seconds later), I finally get onMetaData at this point too. Why doesn't it begin playback right away, or at least w/in a couple seconds? What can cause this bloated lead in time?

View 1 RepliesWith AIR 2 allowing access to mic data, it's possible to save/process audio locally. Adobe provides a WAVWriter example but is there any API access to the Speex codec?

I am trying to import a FlashDevelop project into Flash Builder. I simply started an ActionScript project and dragged and dropped files & created packages as needed, selected "Set as Default Application" on the main file .as file and deleted the default application .as file. But when I compile I get the following errors
[Code]...
In my build path I have Flex 4.5.1 and for framework linkage I am doing "Merged into code".
I am using FMS 3.5 and Flash CS3 (though using action script 2 at the mo)What I have is a simple program that records a webcam and saves the result as an FLV. - Note, I am doing all this locally, NOT over the internet or a local server. FMS is on the same PC as the program.
1) The frames per second does not seem to be fixing to 25fps, but instead seems to be around 15fps depending upon which pc I use. I'm using: cam.setMode( 320, 240, 25 ); to set the size and frame rate in flash.
2) When I get the properties for the resulting flv, it says it is using h.263 codec. Is there a way to change the codec that is used (to say h.264)? Or is this dependent on the version of flash used? ie. would creating it in flash 9 using AS3 give a better quality result?
I'm developing some AS3 that will end up in a mac projector (.app). This app will stream 1080p videos from the local disk. What is the best codec for fluid videos? (no hiccups, fast start, etc) Is there any special setting I have to consider in the code or in the publish settings?

View 3 RepliesI learned from some previous post that the default encoding format used when you publish the camera from a Flash player is Soreson. I'm wondering whether it is possible to select to use other codec such as VP2 or H.264?
View 3 RepliesI use Red5 server 0.9.1 for live streaming from Adobe Flash player to my RTMP protocol transport.I test it with audio data captured from my microphone using flash application and for now transport recieves and recognizes audio packets. For further audio data listening I need to know what audio codec Flash player uses to send data to the Red5 server.Transport doesn't recieve any metadata packets with detailed information about media codec. All I know for now from "connect" message is that publishing side supports the set of audio and video codecs.

I'm using ffmpeg on Windows to create mp4 files for web distribution. As libfaac isn't available, I use libmp3lame to encode the audio tracks. The mp4 are played back with a falsh player (JWPlayer).I was wondering if there were any shortcomings to use mp3 instead of aac on certain devices?
View 1 RepliesPeople have figured out how to use the Google Speech API (Speech-To-Text). I'm trying to get it working with Flash Speex codec, and I just can't figure it out. I've tried inserting frame size byte before each 160 bytes (as some sources say), but this doesn't work. So I post a challenge to somehow translate the flash speex bytes for Google Speech API to understand. Here is basic flex code:

I´m having problems with h.264 in Flash. streaming a h.264 video from Red5 to a Flash client with ActionScript 3 or 4. The original code supports streaming video in .flv format with Sorensen and I would like to support .flv format with h.264 encoding. Does someone know something about? This is my original code:
play_btn.play_symbol_txt.background = false;
stop();
isPaused = true;
var nc:NetConnection = new NetConnection();

I put the h264 packets into flv file with the flv file format in video_file_format_spec_v10.pdf. I used CodecID=7(AVC) and filled video data with h264 encoded packet. But it doesn't work. The codec lib is x264 with CABAC enctropy. The test.flv file in attachment is what I created using x264. Below is the media infomation about test.flv.

Yesterday I was working in an exhaustive animation when the computer turned off. When I turned the PC on again there was a message about a recovery file.

View 3 RepliesI'm toying with an Adobe Air app that plays quite large movies. I want to run it on a 1920x1080 display connected to a Mac. Unfortunately, the movies tend to stutter and I'm betting that happens because I'm not using HW GPU acceleration for H264 playback.
Most of the player code is ported (aka copied) from a web player I built and which runs very smooth on the Flash Player from the browser. So the code shouldn't be the problem.
In the Flash Player, to use GPU acceleration in a fullscreen mode, you have to set the Stage.fullscreenSourceRect property. However, this doesn't seem to work in Adobe Air...
i stumbled accross the following website: URL...As you can see, the site is driven using a hd video. the user can interact with the site by performing little actions with the mouse. I guess this is simply accomplished by seeking through the video using the mousemovements as offset.What i would like to know is, how are videos like this encoded ? How big is the video behind a site like this ? Is the HD content streamed from the server ? What compression would you recommend for similar quality ? Do you guys know a tutorial/article that deals with constructing "video driven" websites like the one above ?
