Jaemin, can you please provide a video showing the level of choppiness?  Is there an expectation around network capabilities, etc. that could affect this?

I have attached recorded video file showing the level of choppiness.

Network status is fine. I have used my phone's tethering to check RTSP streaming.
And, in same network status, android playback is smooth.

Thanks.

Hi Jaemin,

I compared my Flame v2.1 to an Android phone and didn't see significant difference in playback smoothness (at least for the video BigBuckBunny).
I also watched your attached video, actually I think it's smooth enough.
Sometimes the issue could also be caused by the streaming source.
Can you try to compare the performance between B2G and Android using more other video clips to further clarify this issue?

Given the parity with android here, we can seek more improvements in 2.1

I have sent another video showing the level of choppiness to mail.([e-mail])
Since file size is big, I have used my another e-mail account.([e-mail])
You will receive mail from "[e-mail]".
Please check attached video file in email.
You can find that playback is not smooth.

And could you check this problem using FireFoxOS2.0 device?

Thanks.

Thanks! I've already got your video and watched it.
I think I can understand what your mean right now.

I think v2.0 and v2.1 have no difference on this issue.
So far I have no idea about where the performance bottleneck is.
This could be a thorny problem but we'll try to see what we can do.
