[poky][PATCH v6 0/3] Add patches for Gstreamer 1.4.5 base

[Yuqing Zhu]

Fix issue about gstreamer1.0-plugins-base

-ssaparse: Enhance SSA text lines parsing.

-subparse: Set need_segment after sink pad receive GST_EVENT_SEGMENT.

-encodebin: Need more buffers in output queue for better performance.

+subparse works in push mode, chain funciton will be called once

+if set need_segment flag in src pad event handler, the segment
+event will be pushed earlier, result in the subtitle text will

I'm afraid I'm completely confused with this patch series. It started as
6 patches, its now 3 and these patches don't apply against master.

Could someone send the complete patch series that you're asking to merge
that applies against master please?

Cheers,

Richard

Hi Richard,
    Sorry for causing your confusion. Firstly, I sent five gstreamer1.0-plugins-base related patches and waiting for your feedback. Then, I sent three more patches, the status of them is unknown, I am still waiting for feedback. And this time, I sent the following three more pathes. Totally eleven patches of gstreamer1.0-plugins-base in all. I will resend the complete patch series, which will be much more clear.

B.R.
Yuqing Zhu
