One final suggestion, after which my relevant expertise has reached its limit:( Those Android developers I know who are developing apps doing streaming video (or even progressive download) do not rely on the emulator's video codec support: they test on the phone.
Come to think of it, I have seen for myself in my more limited testing that sometimes I can get a video working OK on the G1 phone, but it shows up w/ no video on the emulator. That sounds a lot like what you are seeing. On Jul 21, 8:00 am, Yadnesh <[email protected]> wrote: > Thanks for helping.
