[xine-user] Xine in support for conversational analysis

[Gilles S. <Gil...@ul...>]

Hello.

I work with people doing research in conversational analysis.  Their=20
current source of study is a corpus of audiovisual interviews.
As a first step, they must transcribe part of the audiovisual document=20
into a format suitable for detailed analysis.  Hence they would need a=20
player to view the document they want to transcribe.  Thus I'm looking=20
for an existing efficient and flexible multimedia player that could be=20
used as a component in a GUI transcription software.
Such softwares are being developed (tasx, exmaralda, agtk) but they=20
currently have limited (AVI, MPEG1) or no support for video formats.

I was wondering if xine could be used in that way.  For example, it=20
should be possible to partially redirect sound and video data to another=20
output apart from the usual ones (i.e. sound device and display).  Sound=20
data for example will be used to draw a plot of the sound waveform,=20
where a cursor should indicate the current position in the playback=20
(this might be done with the Snack library)...

I'd appreciate if you could point me to the relevant parts of the code=20
as I'm rather ignorant of multimedia codecs and file formats (I know C=20
though) .
Thanks for any suggestions.

Best regards,
