Hello,
I'm not sure this is the correct forum for the following
questions, but it's the closest I can find. I am implementing a j2me
video capture app and am finding much strangeness on different
handsets. It's almost as if the phone manufacturers don't wish to
implement mmapi/jsr135 fully. Can anyone answer the question: How
common is full jsr135 implementation, specifically video and audio
capture (not just snapshot, but full motion)? Can anyone comment on
this?
Secondly, a couple of specific questions, as examples of above:
1. On a Samsung SGH-A707 phone, I get a return of 'false' when running
System.getProperty("supports.video.capture"), indicating that it won't
allow video capture thru mmapi. However, when running
System.getProperty("video.encodings"), it returns
'encodings=video/H263'. Isn't this a contradiction? If it doesn't
support capture, why would it show an encoding? What am I missing?
2. On an LG CU500, I get a return of 'true' when running
System.getProperty("supports.video.capture"), indicating that it will
allow video capture thru mmapi. However, running
System.getProperty("video.encodings"), it returns 'encodings=jpeg'. How
is jpeg a video encoding? Isn't this only for snapshots? Do they mean
motion-jpeg?
These are both new phones, and both support video capture natively
(outside of java). Am I wasting my time trying to implement a video
capture app in j2me to run on multiple handsets? Is cross-platform
mmapi a pipe dream? Please comment. Thanks!
