Tried new beta build to meet new Apple iOS requirements. It suits, but there's a bug issue.

In new 32.0.109 build it doesn't play sound and/or video. On desktop builds it plays neither video nor sound, neither video nor stagedVideo. On mobile builds (both iOS and Android) it doesn't play only sound, video exists.

After many tries I excluded all reasons. The simplest test application with 32.0 (and many previous) sdk works, and with 32.0.109 it doesn't.

It's ok to work with 32.0 sdk for Windows, Mac and Android. But it's not for iOS. I need sdk that supports 12.1 iOS version.

Any solution with this situation?

With latest AIR SDK 32.0.0.144 beta with Windows devices we still have some problems:

1) If you disable hardware decoder:

NetStream::useHardwareDecoder = false

H.264 videos doesn't shows.

It works fine with AIR SDK 32.0.0.89.

2) H.264 videos doesn't shows with Stage3D VideoTexture. FLV H.263 video with Stage3D VideoTexture works fine. All it works fine with AIR SDK 32.0.0.89.

3) H.264 videos with resolution more than 4096 pixels by any side doesn't shows.

4) Video doesn't work without adding to stage and fails with NetStream.Play.Failed

It works fine with AIR SDK 32.0.0.89.

5) Draw Video to BitmapData just after NetStream.Play.Failed cause exception:

"SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: app:/App.swf cannot access null. No policy files granted access."

It works fine with AIR SDK 32.0.0.89.

With latest AIR SDK 32.0.0.141 beta with Windows devices simple Video and StageVideo for me works fine but we still have some problems:

1) If you disable hardware decoder:

NetStream::useHardwareDecoder = false

H.264 videos doesn't shows.

2) H.264 videos doesn't shows with Stage3D VideoTexture

3) H.264 videos with resolution more than 4096 pixels by any side doesn't shows.

why would you want to disable the hardware decoder ?

my guess is they are using only the hardware decoder without fallback to a software decoder
because Intel Quick Sync Video - Wikipedia

Support for Quick Sync hardware accelerated decoding of H.264, MPEG-2, and VC-1 video is widely available.

so yeah if you disable the hardware decoder it not gonna work

I need to disable hardware video decoder for cases with incorrect functioning hardware (GPU) or GPU drivers and to avoid some AIR bugs to get some functions works fine.

For example:

1) Some Windows and Android devices have problems with GPU (at hardware level) or with GPU drivers or with DirectX or it even doesn't have proper drivers at all. So for some reasons with some devices video playback with hardware decoding just doesn't work properly: solid green color video output, visual artifacts, strong performance lags, poor video playback quality, FPS drops or even application crash.
