Original commit message from CVS: New mimetypes gone into effect today - this commit changes all old mimetypes over to the new mimetypes spec as described in the previous commit's document. Note: some plugins will break, some pipelines will break, expect HEAD to be broken or at least not 100% working for a few days, but don't forget to report bugs

REMOVE list (HEAD)
|
|
==================
|
|
* xmms (depends on glib-1.2)
|
|
* avifile (ffmpeg)
|
|
* openquicktime (qtdemux)
|
|
* stereo2mono/mono2stereo/int2float/float2int (audioconvert)
|
|
* hermes (lcs)
|
|
* mjpegtools (jpeg does the same, make it depend on libjpegmmx instead)
|
|
* modplug (mikmod)
|
|
* vga (unmaintained, not-working)
|
|
* videosink (xvideo)
|
|
* aviaudiodecoder (useless)
|
|
* monkeymedia (licensing issues)
|
|
* wavparse/enc goes in same dir
|
|
* mulaw/alaw become separate mimetypes
|
|
|
|
TODO list (short term):
|
|
=======================
|
|
* v4lsrc/v4lmjpegsrc/v4l2src: fix interlacing (not handled at all...)
|
|
* fix v4l*src ! spider ! colorspace ! xvideosink
|
|
- first sets to PLAYING, then (re-)triggers capsnego - that breaks
|
|
|
|
TODO list (long term):
|
|
======================
|
|
* v4lmpegsrc (*hint* MPEG card needed *hint*)
|
|
* v4l2sink
|
|
* BSD-videosrc (bktr)
|
|
* color correction (brightness, hue, etc.)
|
|
* gamma correction
|
|
|

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}
