flv playback in ios

Oct 19, 2011 5:23 AM

Does anyone know if there are any optimal encoding settings for flv playback on an ipad? I'm using the flvplayback component (flash cs5.5 and air 2.7) but can't get playback on an ipad to be as smooth as on a pc.

    i tried on2 vp6 encoding and work fine both in iphone and ipad , you can use adobe media encoder cs5.5 to encode your vedio.

    I've found the longer the video the worse it plays back.

    Encoding the alpha channel also significantly impacts performance.

    Overall though, it'll be hard to match the performance on a pc.

    If possible, use a .mp4 and StageWebView instead.

    How well does it work if you set CPU instead of GPU?

    What are your video compression settings, and video image size?

    These are the settinsg I use in Media Encoder for my iPad app and they seem to play pretty smoothly.

    As you can see they aren't too small either.

    Make sure you're playing the files back at the encoded size. I imagine having to scale the flv file up/down won't help performance.

    Presumably it's 25fps. 1024x576 is quite a large area of video, it might just be too much to handle. But try extremely low data rates, just to rule out that being the issue. I mean, like 300 kbps. If that then plays well enough, try using 700kbps, that may be good enough quality, and yet play ok.

     

    I have played 2mbps FLV full screen on an iPad 1, but that was most likely 640x360 video scaled up.
