Flex :: Flash Video Playback - How To Determine Seconds Loaded
Jan 11, 2010
I'm trying to accurately determine how many seconds of a video (NetStream) have been loaded so I can scrub/seek correctly. First I tried doing duration*(ns.bytesLoaded/ns.bytesTotal) but this is inaccurate by maybe 15%, ie if that calculation says 20 seconds is loaded and I scrub to 20 seconds ns.time will tell me it can't go past 17 seconds.
I think this is because the size of the file loaded doesn't map perfectly to the number of seconds loaded (obviously), ie as the video loads, some of the bytes loaded aren't the actual video but are overhead of the container/file the video is in. So to load 1% of video you have to actually load 1.15% of the file's size.

1) I want a 60 seconds video to start playing after 40 seconds have been downloaded - to do that I set the NetStream.bufferTime to 40 seconds and retrieve "NetStream.Buffer.Full" event causing the video to really start playing. This step is OK.
2) However, the "NetStream.Buffer.Full" causes data to stop downloading. So the remainder of the video begins to download no sooner than after the 40 seconds have been played. This step is my issue. Can anyone tell me how to avoid this unintended effect? (i.e. playing a video and downloading data at the same time?)

I wanted to know which event determines if an external video is loaded (using Action Script 3, Flex SDK 3.4 compiler and FlashDevelop -VideoEvent is not present here-).
I'm using a flash.media.video component
I've tried with NetStatusEvent.NET_STATUS and "NetStream.Buffer.Full" but it does not seem to work.

Is there any AS to determine the size of the fullscreen playback? Usually I use;
fscommand("fullscreen", "true");
fscommand("allowscale", "true");
But I would like it play back at a particular size like 800 x 600 so the rest of the screen is just a border of the documents colour. Can this AS be adapted to do what I need?

I am using Flash Professional 8 and Dreamweaver 8 to maintain a website. I have just started using flash to show video highlights from high school football games which I record. Using iMovie I export the video as quicktime file and then import to flash to convert to a flash video file to post on the web site. The video coming out of iMovie has very good contrast and the quicktime movie has the same good contrast. When looking at the file in Flash the contrast changes dramatically. I becomes washed out. I am using Max OX 10.6 operating system.

Suppose you have an encrypted video file and the associated AES key. Is it possible to play that video in a flex AIR application without saving the decrypted version of the file? How?

I'm working on a rotating carousel type menu. It has images that rotate around, and when you click on an image, a .flv file plays, then when it's done, it goes back to the menu. It loads the data from an .xml file so it's all dynamically created.
This is all fine and works... locally.
When I upload it to the server, everything seems fine until I click on one of the icons. The .flv plays for 2 seconds, then goes back to the menu. Other flv files on the internet play fine, so it's not my flash player. I tried hard-coding in a video to play, and it has the same problem, it plays the first 2 seconds, then freezes.
Code:
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
[Code]....
I have the program set to go back to the menu when the status of the .flv is: NetStream.Play.Stop
I traced out the status of the video when playing locally, the status goes normally (gets to Netstream.play.stop after the video is done), but when played online, it gets to netstream.play.stop after 2 seconds, then prints that out like 50 times.

I have made a application that plays videos that are stored in a assets folder of the air application but when ever I run it on an hp slate the videos are really choppy. Is there a way to preload the video or does it have to do with the processing power? the videos are 1.72mb or smaller. They are flv format and they auto play when that application is started. I am using flash builder.

I have a very straight forward piece I'm working on that involves copy fading in and out but, instead of using the time-line for timings I'd like to use some script. It's just copy fades in (hold for three seconds) then fades out (hold for one second) copy fades in (hold for three seconds) etc.

I have a video embedded in Flash as an FLV. I'm able to get the video to play through the way I want, but when the video plays through and ends, I want to have two options/"buttons" display that allow the user to either replay the video a la youtube, or link to another web page.
I know it must a very basic question but I can't seem to find any answers. I've included a screen capture of the end of the video.

Anyone know how to vary the playback speed of video in Flash? I'm looking to implement this in an educational website where users can slow down the video or breeze through it by changing the playback.
Here's an example of what I'm looking for: [URL].. Except that this is a PC application, .exe. I'm looking to vary speed WITHIN Flash. I think FLV is not an option because you can only jump from cue-point to cue-point. With F4V work? MP4?

I would like to play back 3 reasonably high res videos (On2 VP6-S) simultaneously in one Flash App (using flash.video, netstream and netconnect - code only). Unfortunately, when I do this, the video playback drops a lot of frames, however, CPU usage does not go much above 50% - spread over both cores. I'm using a Core2Duo. If I play the same 3 videos simultaneously in 3 separate flash apps (FP10), they play much better (and use close to 100% CPU). I even tried creating it as an AIR app with 3 separate windows (NativeWindow), but that made little difference. I have lodged this as a bug via the Flash Bug Reporting System [URL].
And yes, I do need to be doing something as crazy as this - it is for a pretty cool kiosk app, so I know what hardware will be used (and it has a good Graphics Card). One promising workaround appeared to be playing back a single NetStream in multiple Video instances, as it is NetStream that does the decoding, so I could decode once and present it in 3 places. Two of my video objects are actually the same flv (on different monitors), so there would be a 33% saving right there. If necessary, I could encode both flvs into a single 1920x1200 flv (I've checked - it would play back ok) and then use video.mask to show the relevant bits.

I am planning an implementation for a lecture capture solution for a local university. It is supposed to record all aspects of the lecture: the presenter will be recorded using videocamera + mic, his desktop activity is captured and optionally the whiteboard is captured as well (using Mimio). These input streams arrive (as video streams) to a computer that stores the recording on its harddisk. The file format for the recording should be able the hold multiple streams (Matroska for example).
The recording will be available from the uni's website. So at the client-side Flash seems a natural choice.
The player should display the different input sources into different rectangular regions of the player. One region displays the presenter, another region displays the desktop recording.
Is it possible to use a Matroska file as source for Flash streaming? If yes, how?
If no, is there another container format more suitable for this? The FLV format can only hold one audio and one video file. Is it possible to have one Flash client receive multiple streams and diplay them in different regions of its own canvas?
