This problem seems to exist when the resolution is too low.
(The resolution of this media: 176x144)
I will further clarify the root cause.

I verified that HTTP streaming has the same problem.
If the video resolution (width/height) is too low, the seek bar would disappear.

William, you can try to link to the following media, which is also a 176x144 video.
http://10.247.24.86/han.3gp

I think once we resolved bug 1005861, this bug would not be a problem anymore.
Besides, as David Flanagan mentioned elsewhere (https://bugzilla.mozilla.org/show_bug.cgi?id=1005865#c2), this kind of problem might could be fixed by tweaking this file:
  b2g/chrome/content/touchcontrols.css

At last, this is not a bug of RTSP component.
We should adjust it to the proper component, but I am not sure which one.
I found these candidates:
  Firefox OS > Gaia::System::Browser Chrome
  Firefox OS > Gaia;:Video
  Core > Video/Audio

Howie, could you please help to coordinate to locate to the right component?

Hi Hema, this one should be built-in media player's issue, could you re-assign the right person to solve it? thank you.

[Hema Koka [:hema]]

I see that the changes to media controls is maintained by the firefox OS frontend team (based on change history on the touchcontrols.css file). Moving this to Toolkit > Video/Audio Controls component for triage and fix. If I got the component wrong, please correct me.

Thanks
Hema

We don't have much time for implementation here ( aprox ~1.5wk so to 2.0), this is definitely 2.0 blocker as i don't think we allow no seek bar function for RTSP video playback. who can work on this?

Hi Mark, could you take a look and assign to the right person if this belongs to your team? If no, do you know who should in charge of this? Thanks!

After clarification, found that this is only occur while low video resolution, and not happend when turning to full screen, thus i don't see this is critical now. Howie, per team discuss, please remove blocking 2.0. thanks!

Modify the title because it belongs to toolkit component.

No one is actually working RTSP for FxOS for now.
