You could use gstreamer and a gtk canvas widget but i would recommend clutter & gstreamer there both designed for multimedia projects.

Clutter is an open source software library for creating fast, visually rich and animated graphical user interfaces.
Clutter uses OpenGL (and optionally OpenGL ES) for rendering but with an API which hides the underlying GL complexity from the developer. The Clutter API is intended to be easy to use, efficient and flexible.
Clutter currently features the following:
Object oriented design via GObject with a familiar GTK+ like API.
Scene-graph of interface elements with multiple layers, positioning in 3D space, grouping, transparency, scaling, clipping and rotation.
Input event handling.
Frame based animation engine providing path interpolation, transitions and other custom effects via Behaviours and Timelines.
Custom Pango renderer providing efficient internationalized text rendering.
Support for media playback with GStreamer, Cairo graphics rendering and GTK+ embedding are available via optional add-on libraries.
Language bindings for Perl, Python and Mono
Backend windowing system support via GLX, SDL and EGL

Gstreamer

GStreamer is a library that allows the construction of graphs of media-handling components, ranging from simple Ogg/Vorbis playback to complex audio (mixing) and video (non-linear editing) processing.
Applications can take advantage of advances in codec and filter technology transparently. Developers can add new codecs and filters by writing a simple plugin with a clean, generic interface.

And for that little bit extra pro look have a look at

PHAT is a collection of GTK+ widgets geared toward pro-audio apps. The goal is to eliminate duplication of effort and provide some standardization (well, at least for GTK+ apps). It's open source software, licensed under the GNU GPL, version 2.0 or later.

Widgets include:
Fanslider "Vertical & Horizontil"
Keyboard
Knobs
DPMMeter
PPM Meter
VU Meter
And some type of midi drumpad?

Hope that helps
