* sys/ximage/ximagesink.c: (gst_ximagesink_sinkconnect):
Comment out internal resize. It doesn't handle the resulting
XEvent internally, does another try_set_caps() which leads to
a really nice loop.
Real fix will come when Julien and Dave are awake. ;).
Original commit message from CVS:
2004-01-01 Ronald Bultje <rbultje@ronald.bitfreak.net>
* configure.ac:
Fix configure check for mpeg2enc. We need 1.6.1.93 instead of
1.6.1.92, since the pkg-config file of 1.6.1.92 is borked and
it therefore uses the wrong include paths. Too bad... Note
that 1.6.1.93 is not release yet. ;).
Also add a check for mplex, which is now using the lib'ified
mplex from mjpegtools, too.
* ext/ffmpeg/gstffmpegcodecmap.c:
Add codec_tag for 3ivx/xvid. For xvid, this should fix playback
issues. I don't think ffmpeg handles 3ivx correctly, so this
probably won't work. But it won't hurt either.

We wrap mjpegtools mplex. So I rewrote the plugin. The old plugin
had issues, didn't do capsnego, supported only a subset of the
mplex features and required a mplex fork in our local CVS. Plus
that it worked agaist a very old mplex version. Rewriting was
faster than updating it.

Add getcaps() function for proper caps nego. This makes some

* sys/ximage/ximagesink.c: (gst_ximagesink_sinkconnect):
Resize window on new capsnego. This is probably wrong, but
I'm still committing it because with current capsnego, the
first successfull capsnego is auto-fixated, therefore rounded
down to the lowest values in the caps. this results in a 16x16
XWindow that is not reized when real capsnego finishes.
Dave, I see more cases of this, do you know a proper solution?

Improve mpeg2enc detection. This is for distributions that do

for might there ever be ABI incompatibility.
* ext/mpeg2enc/gstmpeg2enc.cc:
Add Andrew as second maintainer (he's helping me), and also add

Original commit message from CVS:
- Fixing framerate on caps renegotiation. We memorize it on sinkconnect to set fixed caps on renego.
- Homogenized indentation.
- Removed some comments.
- Fixed the caps renegotiation new ximage creation (it was creating a new ximage on every configure event even if window's size has not changed)
- Removed pointer coordinates translation in navigation_send_event as we are not doing scaling. videoscale should convert those events is scaling there is.
Original commit message from CVS:
I m glad to introduce you xvimagesink which the brother of ximagesink using XV extensions with both XShm or not... It grabs the XV port so no possible overlapping of overlays. If multiple ports are available i take the first non grabbed one...
Wheeee !!!
Original commit message from CVS:
Fix device probing from multiple childs. It's done once in the parent class only now, but the childs do get the correct values. Also fixes an incorrect succesful state change if we opened a v4l device that doesn't have the capabilities that are needed by the plugin.
Original commit message from CVS:
Moved the xevents handling in a function. Trying to get caps renegotiation to work.
The xwindow is not resized by sinkconnect as i still don't know what i ll do for that autoresize behaviour.
Original commit message from CVS:
Remove all config.h includes from header files, add it to each source file and remove duplicate config.h includes from several source files
Original commit message from CVS:
Some interface implementations for video4linux/video4linux2 plugins:
* a Tuner interface, with which one can select inputs and stations. Audio
work is underway here, but unfinished.
* A Xoverlay interface with which one can do simple overlay. Similar to
the API of the v4l/Xv XFree86 extension. Widget implementation for
GTK-2.0 coming up in the sandbox.
* Colorbalance - for adapting colors (brightness, contrast, etc.) - pretty
basic and maybe somewhat overdesigned. But it'll do for now.
Apart from these interfaces, there's also a loadable library 'xwindowlistener'
that listenes to X for the movement of a window and the overlap of other
windows. This is partly copied from xawtv (and thus partly GPL :(), but it's
needed for the xoverlay interface implementation in the v4l/v4l2 elements.
Lastly, some small changes to remove redundant properties from the v4l/v4l2
elements since these can be done much simpler. Comments appreciated!
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
Original commit message from CVS:
compatibility fix for new GST_DEBUG stuff.
Includes fixes for missing includes for config.h and unistd.h
I only ensured for plugins I can build that they work, so if some of them are still broken, you gotta fix them yourselves unfortunately.
Original commit message from CVS:
Plugins cleanup:
* stereo2mono, mono2stereo, int2float, float2int: replaced by audioconvert.
* stereosplit replaced by oneton.
* vumeter replaced by level (and was broken anyway).
* avifile replaced by ffmpeg.
* mjpegtools duplicates functionality of jpeg. jpeg now works with jpeg-mmx,
too, which makes mjpegtools unneeded.
* allow for jpegmmx instead of jpeg.
* openquicktime replaced by qtdemux and ffmpeg. Broken anyway.
* XMMS is broken and will never be fixed.
* vga is broken and will not be fixed anywhere soon.
* videosink has never worked. If it works, add it back to replace xvideosink.
Original commit message from CVS:
Some final fixes for the v4lsrc elements.
* remove software sync thread (use GST_ELEMENT_THREAD_SUGGESTED instead)
* make all src elements threadsafe
* fix num_buffer argument setting in v4l2src (VIDIOC_S_PARM)
* re-add bufsize (RO) for v4lmjpegsrc
* fix the A/V sync calculation in all elements (spvf=GST_SECOND/fps, not GST_SECOND*fps)
* probably some more crap....
With all this, it actually works quite well. The TODO files describes the
next steps in order to make a full-featured video recorder based on these
elements and GStreamer (bottom). Making a simple recorder should be fairly
easy now, btw.
Original commit message from CVS:
This implements filtered-caps negotiation for all the v4l*src elements, and removes the accompanying properties since they're no longer needed
Original commit message from CVS:
make v4l element do all calls in one thread, this makes performance much better (because of kernel locking, more threads doesn't make sense anyway)
Original commit message from CVS:
another batch of connect->link fixes
please let me know about issues
and please refrain of making them yourself, so that I don't spend double
the time resolving conflicts
Original commit message from CVS:
v4l plugins:
* add open/close signals
v4l2 plugins:
* add open/close signals
* move source format enumeration from v4l2element to v4l2src
* adapt to the final v4l2 API in kernel 2.5 (patches for 2.4 on http://bytesex.org/patches)
* small tweaks
Original commit message from CVS:
This patch fixes some issues caused by design issues in video4linux, adds
some nicety to video4linux2 plugins and does some more evil stuff:
* video4linux doesn't tell us which formats are supported by a card, so
the only way to know this is by simply trying it out. This patch adds that.
* v4lmjpegsink didnt have a bufferpool yet - is integrated now.
* all copy() bufferpool functions have been removed since they're not needed.
* v4lmjpegsink doesnt have a free() function, because hen playing the frames,
all this is already handled. When the frame is not played, nothing has to
be done. In total, the function is not needed.
* adds a get_caps() function to v4l2src
* some minor crap
Original commit message from CVS:
This patch:
1) would provide v4l2 plugins, if only the CVS server wouldn't bork on all commits :-(. This patch will come later on in a separate commit when SF fixes her repository.
2) it fixes capsnego for all the video4linux1 plugins
3) it rewrites the debugging of all v4l1 plugins, which now make use of the standard gstreamer debugging features (gst-mask=...). This should make debugging video4linux1/gstreamer problems much easier then it used to be.
