What is the best way to transcode audio and video to show on the web?
I need to do it programmatically. I'd like to do something like YouTube or Google Video where users can upload whatever format they want, and I encode it to flv, mp3, and/or mp4. I could do it on our server, but I would rather use an EC2 instance or even a web ser...
Are there any .NET-specific tools out there that can parse / access the elementary data streams in an MP4 file?
Thanks,

I am planning to buy portable video player (with MP4 support) to view the msdn web casts, mostly WMV files.
Has anyone tried viewing the web casts on a portable player. Which one would you recommend. (e.g. Apple iPod nano 4G)
Do keep in mind these web casts show code being written in Visual Studio, so the display needs to be clear enou...
I have a Android app. It recieves videos in .flv format which is unplayable by the Android phone. I was wondering how to convert the file to MP4. I could use FFMPEG, but I do not know how I would get it onto the phone, and how it would work on multiple phones if it was compiled for a single one.

One of the features of the Flash app I'm working on is to be able to stream a webcam to others. We're just using the built-in webcam support in Flash and sending it through FMS.
We've had some people ask for higher quality video, but we're already using the highest quality setting we can in Flash (setting quality to 100%).
My understa...
I have an HTC Touch HD on which mp4 videos downloaded from Google Video play the best, both in terms of video and audio quality.
So I am wondering which settings exactly Google Video uses to encode videos into mp4, so that I can replicate it for videos not available on Google Video. A tool which reads an mp4 file and tells you all the e...

Hello,
could you point me to docs/snippets/blogs, which explain
how to record Apple lossless audio files on the iPhone, please?
I've inspected the audio recorder example from the Apple
Dev Center, but couldn't figure out, which setting I have
use for lossless audio.

The MPEG-4 file format allows multiple streams to be present in a file.
This is useful for videos containing audio in multiple languages. In the case of such a video, the audio streams are synchronized to the video.
Is it possible to create a MPEG-4 file the contains desynchronized audio streams, i.e. the audio track are played on afte...
I'm looking for a flash video player that can play mpeg1 streams (alternatively MP4 would work too). Are there any?

I am trying to troubleshoot this code and am running into a dead-end, so I thought I would ask my first question here. I have three questions:
1) What is the best approach to embed an mp4 for an iPhone specific view, preferably without using Javascript?
2) Are there any preferred practices to debug code on an iPhone?
3) Can anyone tel...
Can I embed MP4-files streaming using a flash-player? I find several places it is mentioned, but some places also mention that flash-10 might be a requirement, it might now work well for streaming etc...
Are there any limitations I should be aware of - and which embeddable flash-player works well?

Hi All,
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 li...
I was wondering how do you inject metadata into an f4v file with quepoints? I've been reading somewhere that it's either during encoding or a custom actionscript that embeds when the file runs.

I am trying to play an online MP4 http://www.elecard.biz/clips/mp4/misc/River.mp4
With WMP 12 that ships with win7 RC. The media does play but the Buffering takes ~3 minutes which makes it appear that the file is being downloaded before it is playing. Once the media has been played, subsequent Play causes it to start instantaneously, s...

I've noticed FLVs are ubiquitous in flash video, but I'm looking to use MP4s / H.264 in my flash video app. Has anyone had any problems with using MP4s? I'm just doing progressive download.
Thanks,

I've got a Sony network camera (SNC-RZ25N) that I am trying desperately to get data from in some meaningful format. The documentation says it sends MPEG-4 raw data, but is not more specific than than. I can capture a segment of the stream using curl ( http://techhead.biz/media/tsv.m4v ) and it will play using VLC and ffplay (though it pl...
i need to build a audio/video streaming server in java. i am thinking of using mp4 container format and real time protocol. i might want to modify the codec for my need. i don't know what apis to use for this. i don't want to implement code to parse mp4. could someone give me a direction?
