Decodebin and queue

[Duchassin Frederic]

I can't use decodebin3. I'm working in a embedded device and gstreamer version is 1.0. Decodebin3 is not installed.
I don't really know why this queue between parser and decoder gives better result...
So what I should do ? build the whole pipeline myself ?

I have the impression that this case will work with decodebin3, best is to give it a try. You can also split your pipeline using parsebin !
queue ! decodebin. Though, overall, I don't understand why adding these queue will make any difference, maybe you need to tweak the multiqueue settings ?
