Well it depends how the pipeline retrieves data from the source, there are 2 modes, push and pull. By local source you mean file:///? In that configuration push mode is selected (I think) and filesrc has a complete access to the data, and then seeking is easy. But for an http:// source, where we can't randomly access data easily, we work in pull mode and that's a bit more complicated.</pre>
