[vlc-devel] Timecode support in VLC Player

Hi, VLC team!

I would like to get some features re timecodes and SMPTE support in VLC player (there are many of us: https://forum.videolan.org/viewtopic.php?f=7&t=58011).
I'm looking for a developer(s) who can devote some time to this task.
I will provide Design Document and funds. My estimation is about 2000 euro for this amount of work but this is discussable.
Could you advise what's the right way to find the developers?

Here's the requested feature brief description:
We are a software vendor for television companies. We need a standalone solution to view (play) and mark segments (pieces) in media files.
Each frame in a video can be coded with a timecode (TC) which basically looks like "hh:mm:ss;ff" (ff stand for frames, note varying delimiters). Each segment is a pair of timecodes: start (SOM) and end (EOM). Key point here is the frame-accuracy. Some media containers (ex. WMF, MXF) support a particular field in each frame with the explicitly stored TC (http://msdn.microsoft.com/en-us/library/windows/desktop/dd562647%28v=vs.85%29.aspx).

1.       Add new navigation controls to the panels and menus

2.       Add new controls to mark a pair of SOM-EOM and send this info to another process by RPC/message.

3.       Support frame-accuracy and TC calculations for these formats (autodetected by FPS):

*         25 FPS (PAL)

*         29.97 FPS (NTFS with dropframe - http://en.wikipedia.org/wiki/SMPTE_timecode)

*         30 FPS  (HDTV)

*         60 FPS (for future use)
We have some groundwork on timecodes calculations (C++ classes to parse/generate correct SMPTE timecode from/to absolute frames number) and can provide them to the community.
Mockup of interface changes (buttons could be rearranged however):
