TODO list (short term):
=======================
* v4lsrc/v4lmjpegsrc/v4l2src: fix interlacing (not handled at all...)
TODO list (long term):
======================
* v4lmpegsrc (*hint* MPEG card needed *hint*)
* v4l2sink
* BSD-videosrc (bktr)
Useful Documentation:
=====================
MJPEG/V4L API : ./videodev_mjpeg.h
V4L API : /usr/include/linux/videodev.h or
/usr/src/linux/Documentation/video4linux/API.html or
http://linux.bytesex.org/v4l2/API.html
V4L2 API : /usr/include/linux/videodev2.h or
http://v4l2spec.bytesex.org/
BSD/Meteor API: /usr/include/machine/ioctl_meteor.h
mjpegtools : http://www.sourceforge.net/projects/mjpeg
Capturing:
==========
* sound is the master clock
* it's probably a good idea to create an audiosource element:
- autodetect alsa/oss
- first try alsa, then oss... they work the same internally
* same for videosource:
- autodetect v4l/v4l2 + mjpeg capabilities
- for this, just open device using v4l2element. On success:
+ use v4l2
- on failure:
+ use v4lelement and query for MJPEG capabilities
+ if that's available, combine caps of v4lmjpegsrc and v4lsrc
* both sources run in their own GstThread with a high priority
* an encoder element takes care of encoding + muxing. A toplevel element
(reverse of spider) is probably a good idea here. How? Don't know...
* format negotiation via filtered caps
* statistics via listening to the frame_{lost,inserted,deleted,captures}
