If you are using Wowza Streaming Engine (Wowza 4.0) or newer just follow the steps from the documentation. This article is relevant only for versions of Wowza up to 3.6 Introduction With the launch of Flash Player 11 (4th Ocotober 2011) Adobe introduced the H.264 video codec in Flash Player for video encoding. For those of you who don’t know yet what H.264 is, it is a standard for video compression, and it is currently one of the most commonly used formats for the recording, compression, and distribution of high definition video. The final drafting work on the first version of the standard was completed in May 2003. The Problems: There are 3 major media servers on the market: FMIS, Red5[…]
A week ago we’ve announced that Adobe will support h.264 video recording in the next version of Flash Player 11. Since then we’ve made some tests . Here’s our setup: Flash Player Incubator preview version a special build of our video recorder (HDFVR). Flash Media Server 4 a Microsoft LifeCam Cinema HD web cam. Run of the mill laptop with Dual Core Intel P8400 @ 2,26GHz CPU Here are our conclusions: Recording HD (1280×720) H.264 video (main profile) maxes the CPU at about 20 fps. It would go higher in fps if I would have a better CPU. The sound is encoded with Speex, there’s no AAC option. On the media server the video+audio data is saved in a F4V[…]
7th of May 2014 update: We’ve created a patch for Red5 1.0.2 that fixes the recording issues and compiled a new Red5 build that includes the patch, more details in this blog post. 5th of June 2013 update: Flash Player 11.3.300.257 (the 1st FP 11.3 release) released on the 8th of June 2012 removes the internal upload limit of FP. 28 April 2011 update: updated with latest available information on the issue and link to Red5 1.0 RC1 fix. This post is part 3 of our 3 part series on recording high quality Flash video over slow connections. In theory whenever someone is trying to use a flash video recorder to: record audio/video at a data rate higher than the upload[…]
This is part 2 of our 3 part series on recording high quality Flash video over slow connections. As explained in the first part, a big buffer should be used in the recorder flash app so that the video and audio data has where to wait before its turn comes to travel to the media server. When the user stops the recording (by pressing a STOP button for example) most probably there still is some audio & video data in the buffer, data that has not been sent yet to the media server. Part 2: wait for the audio and video data to reach the media server before we display any SUCCESS message to the user Otherwise you will most[…]
This post is the first part out of a 3 part series on how to record high quality flash video over the Internet. We’ve learned a lot while doing video recorders for our clients and while developing the AVRecorder bundle and we would like to share some of that knowledge with the community! At the end of this 3 part series you will be able to record DVD like videos over the Internet using a simple audio video recorder made in Flash or Flex Builder (as2 or as3). So, Part 1: In the client swf application use a big buffer on the outgoing stream. All flash video recording applications are made out of 2 parts: the client side application, (a[…]
