Thanks for the answer, Jona. I have noticed the better initial response time in Beta.
I think I have an answer to my question.

XiiaLive Pro works with either FFMpeg or Android. XiiaLive Beta works only with FFMpeg.

So, it seems that in future only FFMpeg should be used.
Jona, the latest version released today still has this problem.

However, I've installed the Beta version, and I'm pleased to report that it works properly.

Any idea when the fix will be released to XiiaLive Pro?
I have your latest update from the 6th. Alas, the XiiaLive Pro still has the problem with the seek bar. Any idea when this will be fixed? Thanks.
@Jona, I look forward to the new engine. The existing one is pretty awesome already.

I shall be happy to test the Beta version; how would I get it?
XiiaLive Pro on Nexus 5 Android 4.4

I have the same problem with the seek bar. It will rewind only to the beginning.
