I'm working on our back-end encoder service which does an awful lot of video transcoding, and a very small amount of joining of video files. The transcoding is done using the On2 Flix engine for Windows which works very well, but unfortunately it isn't able to join files (at least as far as I can ascertain - neither the help nor the su...
I'm working on our encoding software, and have come across a strange issue where files in a 16:9 aspect ratio are being played in 4:3 in some players, post-transcode from WMV to MP4. Using ASF view I can see that the source WMV file appears to have incorrect data in its BITMAPINFOHEADER structure (it reports that is has 4:3 dimensions bu...
I need to be able to programmatically transcode mpeg-2 files to .mp4, .mp3, .wmv, .rm (optional), and .flv (optional), and hopefully generate a thumbnail as well. I found the Java Media Framework, but it frankly looks pretty crappy. This will be running a Linux server, so I could shell out to ffmpeg using Commons Exec - does ffmpeg do ev...
I am looking for a java library to efficently/fast transcodig and manipulation mp3 files. I am working on a sophisticated streaming server that mixes music and has some other functions to allow to users to interact with each other. A recommendation functonallity for example should fade over the stream of the sending user to the reciever ...
Hello guys, I've a C# program generating JPEG images in realtime, i need to (continuously) generate a video from the images and stream it (also in realtime). I've used ffmpeg to transcode an input video source and stream it, doesn't ffmpeg have an option to get the input as a set of images(always being generated) and make the video out ...
A client of mine needs to accept a bunch of different video files and convert them to FLV. My experience with FFMEG on a previous project has highlighted that there will be some troublesome files. Depending on the price my client will pay for a professional service. What are people using and how are you finding the service? Thanks. ...
I've got a video camera that I'm using to capture video; the camera records in H.264 at 720p resolution. I'd like to transcode this stuff to a simpler, smaller format; something that will work properly on digital photo frames that support video, for example. As well, I'd like to transcode to DVD format where possible, so I can burn DVD...
For bandwidth reasons I would like to use Apple's implementation of the IMA4 format available for recording on the iPhone. This format is great for space, but it seems to be hard to find any programs that can transcode it into something like linear PCM or MP3. I've tried sox and Transcode to no avail. I need to be able to do this automat...
Hello there Recently I was approached by a guy who wants to do video transcoding using the GPU. He basically wants me to create him an application that he can sell or gain revenue from advertising. Now he has basically asked me to tell me what I can achieve with 5000 US dollars of pay. Now, I am a graduate student and won an award fo...
I wan't to play video in fullscreen mode on the iPhone, but when I try to figure out how to transcode my videos I get confused about the video format specification from Apple on http://www.apple.com/iphone/specs.html Video formats supported: H.264 video, up to 1.5 Mbps, 640 by 480 pixels, 30 frames per second, Low-Complexity v...
Hi, I have a video file I don't know what format it is. Is there a software can analyze what kind of video container / compression format it uses? I tried Gspot, but it doesn't work (Show "Unknown format") I am sure the file is using some kind of public standard codec because I can use a media converter convert it to avi or mpg4 file...

Hi, I have NSKeyedArchiver and NSCoder data being persisted (as .txt files) and working great. When I deploy new builds to the iphone, the text files are still present - in other words, they are not being written over. However, I want to make sure that the text files will persist when an itunes delivered update of my application is m...
Let me first state that I do not know Java. I'm a .NET developer with solid C# skills, but I'm actually attempting to learn Java and the Android SDK at the same time (I know it's probably not ideal, but oh well, I'm adventurous :)) That said, my end goal is to write a streaming media player for Android that can accept Windows Media str...
I'm writing a chrome extension that works with a website that uses iso-8859-1. Just to give some context what my extension does is making posting in the site's forums quicker by adding a more convenient post form. The value of the textarea where the message is written is then sent through an ajax call (using jQuery). If the message cont...
I usually look to SoX or Window's built in audio libraries for this stuff, but it appears that neither have G.726 codecs. So I have a sequence of bytes that I know are encoded as G.726 although the bit-rate and whether it is mu-law or A-law is not known at this time (experimentation will determine those parameters), and I need to decode...
Hey all, I am looking for some type of SWF transcoder so I can convert SWF files to .avi's. Preferably something that we could hook into our Java architecture. Any suggestions? ...
$(".container").hover( function(){ $(".child-1").hide(0); $(".child-2").show(0); },function(){ $(".child-1").show(0); $(".child-2").hide(0); }); A project I have requires that I use mootools, but I never used mootools, and jquery makes much more sense to me. Can someone ...
Lets say you have a 96 kbit mp3 and you Transcode the file into a 320 kbit mp3. How could you programmatically detect the original bit rate or quality? Generation loss is created because each time a lossy algorithm is applied new information will be deemed "unnecessary" and is discarded. How could an algorithm use this property to det...
