Building a DVR application with Gstreamer.

[Peter Cai]

Hi all,

I am preparing to build a DVR (Digital Video Recorder) based on gstreamer.

Basically, what it does is:

1. Get encoded H264 D1 Element Stream from hardware, an encoder card.
2. Save the video stream in mp4 format to hard driver.
3. When user requests, send out the stream by RTP.

So I think the gstreamer's pipeline concept are perfect for this task and I've finished reading the tutorial of gstreamer.

My questions are:

1. What plugins' docs should I read for further info.(There are so many gstreamer plugins)
2. It's said that "Manually adding or removing data from/to a pipeline" is NOT suggested, 
then what is the proper way to add the video stream from the hardware SDK to a pipeline?

Thanks in advance.

Those of the plugins that you need :). But it would be good it you play
a bit with e.g. gst-launch. Look at the examples we have in each of the
gstreamer modules (under test/examples).

Write a source plugin for that. Is that card using a standart linux
kernel interface or is there only a custom driver for it?
