How can I record and save flash video's with a

问题:

Right 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 code 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?

This is because of how FMS records the mp4 content, quite a few players won't be able to play the videos.

Download the Adobe F4V Postprocessor at this URL: http://www.adobe.com/products/flashmediaserver/tool_downloads/

This should convert the video so it will be playable in other players.

Edit: I just tested the tool with some videos, it will indeed solve the issue of recorded f4v videos not playing in other players

Use ffmpeg to convert the f4v file to flv using the following command:

ffmpeg -i file1.f4v -sameq file1.flv

Check the enter link description here from Pavel Langweil. He have a great Theora / Vorbis encoder that generates small ovg files that you can easily convert to mp4 using ffmpeg.
