StageVideo seek not working correctly with h264 on Android 4.x

hi,

 

my setup:

mp4 video encoded h264, keyframes set @ every second

adobe air 3.5.0.600, swf-target=17

device: asus nexus 7 tablet android 4.2, kernel version 3.1.10-g22b4fcd

rendermode: direct

 

the problem:

using seek while mp4 video encoded h264 paused not update video frames.

it updates frame when video resumed.

 

seeking while video not paused works, doesnt smooth because video plays , seeks @ same time , cannot seek backwards while video playing.

 

i've finished ios version of app in march of year adobe air 3.2 seeking , code worked without seeking problems using same video file.

 

information problem:

1. stagevideo available , being used
2. stagevideostate tells me video correctly accelerated
3. netstreamstatus tells me netstream.seek() starting , ending, no netstream.seek.failed
4. netstream.time shows me video seeking , time correctly updated after every netstream.seek()

 

solutions , workarounds i've tried (because need finish app soon):

1. using code needed playback video stagevideo, make sure not caused someting in code
2. using adobe air 3.2 & 3.4, still not working
3. using other mp4 videos web make sure it's not video
4. changed stagedisplaystate fullscreen normal, make sure not happening in fullscreen mode
5. disabled stagevideoevent.render_state handler in resized stagevideo.viewport , set viewport once fixed values
6. tried using smart seeking netstream.inbufferseek enabled , using either netstream.seek() or netstream.step()
7. tried different numbers netstream.seek()
8. using flv video file encoded on2 vp6 codec , flv video file i've downloaded web.
   even though said should work doesn't, flv video not being rendered (stagevideostate says render_status_unavailable) can hear audio.
   i've tried adobe air 3.2 & 3.4
   seems bug.
9. fallback standard video object , rendermode cpu works performance of updating video frames while seeking not @ because stutters/lags
10. using f4v video file h264, seek doesn't work @ all, netstreamstatus says netstream.seek.failed

the user responed 2 days ago seeking still bit "iffy" seems use on android phone not tablet.
