Brad -
I read another post that talked about the 30 fps spec. Video size is
320x240. I notice that I only get the VideoSize error when I push the
file to the emulator after starting my app. If I restart the
emulator, then I get the prepare failed error, which is probably the
actual issue.
Dave - Not sure what the frame size is or how to tell, sorry, not much
video experience.
I was guessing that I only had G1 specs. I can't seem to find
anything definitive about the emulator.
Unfortunately don't have an actual phone right now. I'm creating a
demo for my boss, and will hopefully get one out of it if I can
demonstrate it has some value.
thanks for your time guys.

You left out a key detail - what is the frame size?
The specs you quoted are for a G1 device - the emulator is probably
not quite that good. In addition to running soft codecs in ARM
emulation, it's also doing color space conversion, scaling, and
rotation in ARM emulation.

I'm trying to get video functions working on the Android emulator,
using the MediaPlayer demo apis app.
I'm having a hard time getting a file that is properly encoded. I
could use some help understanding the specs and how to meet them.
From what I understand, the emulator cannot handle streaming video,
but you can play video locally from an emulated SD Card. Preferred
format is H.264 Baseline, which is the same as MPEG-4 AVC. The
Baseline profile seems to be the key, and what is probably giving me
problems. All I really know is that b frames are not supported in
that profile. From other information I've seen, looks like you want
something with 30 fps and max 600 kbps bitrate.
Does that sound correct?
I've created the emulated SD Card and pushed my video to it. I've
tested other 3gp videos, that at least played (poorly), so I know I
have that part right. But with my mp4 video, I either get an error
with getVideoSize returned -1, or prepare failed.
The file I'm trying to play was originally sourced from a flash video
off the web, with ext .f4v. I'm using a program called ImToo FLV
Converter (any better suggestions?), and setting the target profile as
MPEG-4 AVC. I've specified 30fps and a Level of 12, which seems to
correspond to Level 1.2 referenced herehttp://en.wikipedia.org/wiki/H.264.
It has an expert panel where it allows me to enter a b_frames
value. I put False, although I don't know if that's what I should
enter there (other options use False keyword I noticed). I have an
email to their support on that.
After conversion I pull up the file in quicktime and check the movie
stats and it shows the file as a H.264 with 30 fps with a bit rate
under 600, seems like I'm close to teh specs and the conversion is
successful. Still no cigar when using in Android though..
Can anyone give me some suggestions? I'll post the file if someone
has the talent to analze it.
Thanks for taking your time to consider my problem!
