Thank you for your input
I'm not needing 200fps, in fact the purpose is to go from 30fps on
down to 5fps
I'm trying to get a video player that will play at normal speed and then
slow down to around 10x slower
frames.incrementProgressBy(300-(playSpeed*30)); // 327-(playSpeed*30));
frames = frames.getProgress();
mBitmap = retriever.getFrameAtTime(frame*1000);
When playSpeed is 0 then increment is 300 thus getFrameAt is 300,000
When playSpeed is 9 then increment is 30 thus getFrameAt is 30,000
Currently, the code slows the playback time. I have a 15 sec test video
at playSpeed 0 it plays for 15 sec at play speed 9 it plays for 2
min 30 sec
Time wise Only, this is perfect, but video play back quality it is
jerky / skippy.
For example, the person walking they are moving towards the camera
but the left leg is always in front, never left, right left. (Which is
what you see when you
play back using gallery)
Also the playback size is around 1020 x 600, would be nice to have it as
large as possible
thou I understand from the problems I'm having I might have to scale
back to around
800 x 600, thou this is NOT ideal.
I will try adjusting the mHandler.postDelayed(buffering, 1); to ,
40);
and keep working
With regards to media player, I had tried both MediaPlayer and VideoView
The issue I ran into there was
E/Surface(25854): surface (identity=1038) is invalid, err=-19 (No
such device)
My main Activity calls a Fragment which is inflated, and I add to the
FrameLayout
the videoView or MediaPlayer dynamically
The overall is you can select any media type jpg, png , or 3gp
and you can zoom in and zoom out, draw lines , change colors , etc..
This is all accomplished with transparent ImageView layers stack on top
of each other
It works great for all images, fails when it comes to video. I have
been stuck on
this for about 5-7 months now, if it's not one problem it's another.
I will also try the dynamic MediaPlayer again
BelvCompSvs, can you please further explain
for what you want to do the ICS [14] is exactly what that is for
Again Thanks to all

Iam trying to call it every 5ms But I would settle for as fast as possible.
Um... I don't think you have a choice, unless you can settle for impossible.
Why do you need 200fps?
I have tried so somehow buffer, thus trying to do all the I/O first and then
just view
but this has failed hopelessly I can only load 15 frames into memory and
then get an OutOfMemory
Do you by any chance know how to find the bandwidth of the Xoom and Sony S
bus what is it capable of
If I have to call every 20ms but get a smoother flowing video playback that
would be fine.
20ms still gives *very smooth* playback / animation. Go for 40ms - it
is still standard for TV, cinema and DVD (give or take).
Experiment and see, what is possible, but to be honest I think you
either aiming too high or approached it from a wrong angle.
If you are displaying it only as 320 x 180, why not transcode the
video to that format and save on bandwidth and processing for scaling
down?
But the most important question is, why don't you use MediaPlayer?
I am not sure what are you trying to achieve by extracting frame by
frame from a movie clip and displaying them as still images as fast as
possible to achieve smooth transitions as in a movie clip.
