Android on Beagle: Video is jerky:Is it the Issue with the display driver or timestamp handling in pvcore?

Hi,
I have downloaded and using the Android Build on beagle board, and
using the opencore(not the GStreamer). When I drop my neon based H.264
decoder component and build it, I see some jerks in the video.
Initially I thought that it is an performance issue but when I lowered
down the bitrate and the resolution of the clip, the jerks persisted.
I guess, either there is an issue in the code which handles the
timestamps etc. or there is an issue with the display driver itself

Can anybody let me know if there is any known issue with the display
driver included in Android Build? Where can I get the latest display
driver? Can anybody give me the contact details of the right person
for this issue?

Help would be appriciated.

Regards,
Sanjeev Kumar Verma

Android on BB is very "young", most people are happy to have it running
at all, so not much about video performance yet, but we will be happy to
hear from your success if you make it work.

Vladimir,
We have developed Neon based H.264 decoder and testing it with the
Android on BB. Here we see slight jerkyness. When I print the input
time stamps inside my H.264 decoder component it get some wrong
constant negative value. In case if it had been proper I could have
derived the output time stamp from it and pupulated.
I want to know how a video component should populate the ouput time
stamp?

Thanks and Regards,
