I tried something like you said : import flash.net.NetConnection; import flash.net.NetStream; import flash.media.Video; var vid:Video=new Video(); var nc:NetConnection = new NetConnection(); nc.connect(null); var ns:NetStream = new NetStream(nc); vid.attachNetStream (ns) addChild(vid); ns.play("http://marcelfahle.com/video/h264/bonifacio576/bonifacio-576.mp4"); Must I make anything else? Thanks! ;) Hey I couldn’t play de video! I tried something like you said :

I created a MP4 v2 and this will not play back in Flash using a netstream. I can make mov's play fine. What were the settings you used to export out of premiere.

It doesnt work right in various ways, but it does make nice low use of CPU in fullscreen mode. Jeroen is waiting till the new flash player is released n final before adding this acceleration, I believe: http://www.unquack.com/mediaplayere.html cube, its a nice idea but will probably run into some problems with most devices recording the older mpeg4 not h264, so compatibility with flash not guaranteed. I tried with the 640x480 type .mp4 that the nokia N95 can record, and it didnt work, got sound but no video. The N95 can play h264 but I think it only records to older mpeg4. But maybe I did something wrong, or this will be improved in future, but it may not, still I suppose eventually more devices will record to h264 anyway.

My Nokia E70 records movies in mp4... thinking of mobile video-blogging and will give it a try. If anyone is interested I will publish my results here. btw: just an idea since I often blog with my mobile via postie (supersmart wordpress plugin!).

The MC H.264 decoders that Adobe has licensed are great for their ability to handle so many varieties of H.264 and for how well they perform, but there are unfortunately still a number of decoding (and encoding)bugs that they haven't ironed out. We have a number of decode bugs open with MC at this time. Generally, the time for them to fix the bugs we have reported has been around 4 - 8 months. We just reported this and another involving chroma playback problems with HP/HL encodes. Good news is though, this hasn't always been a bug with MC (in fact, I think when Elecard was writing their decoders was when it was OK) so the fix may come sooner than usual.

The camera used for the 1080p by the way was a Sony F950, so the beginning quality should be perfect. Data rate is 1922.42kbps (according to QT), 23,98fps. I have reencoding it to 720x405 and 768kbps video, and trying again. Export using QT7 Pro and the MPEG4 option, but it still had these massive aberrations. It played back smooth, though, inside the browser, and in fullscreen. the same was true for a differen video, also preencodet in MPEG4/H.264 (handbrake), when exported using the iphone setting in QT Pro. JW player played it with the .m4v extension, though, so no need to change m4v to flv! I later found out that the issue was with JW FLVplayer 3.11, and a modified verion of 2.4 (blip.tv) played it back flawlessly, with the .m4v extension, and even .mp4.
