[vlc] Streaming video and metadata

[Wayne Yu]

Hello VLC developers,

I have MPEG2 TS and RTP video streaming to a computer via UDP. Along with 
the video are metadata that provide real-time information that describes 
the video. The metadata are packaged in KLV packets described in the SMPTE 
336M protocol.

1) From what I researched, VLC is not able to parse and display these 
metadata which means we would need to add in that functionality. We have a 
preliminary DirectShow filter that is able to parse the metadata, but I 
believe VLC is not able to integrate with a DirectShow like a Windows 
video player. Please correct me if I am wrong.

2) With metadata is in the video stream, can VLC demux the stream to allow 
metadata processing? If so, how?

3) If we need to add metadata displaying capability to VLC, what is the 
best approach in doing so? Would we need to modify the main VLC code or 
are there APIs that we can use?

Thanks for you help.
