* use Py_ssize_t as index type (cf http://www.python.org/dev/peps/pep-0353/)
 * fix audio_[gs]et_channel parameter/return value type

(Currently RTCP only Sender Reports are implemented.)

RTCP is auto-enabled for RTP/TS but this could be used by the RTP stream
output plugin to enable RTCP too (in that case, RTP encapsulation is done
in the stream output plugin, so the access output cannot know if it should
do RTCP or not).

Mac OS X gui: Make sure that misc.h is included as our NSScreen extension is used here. (Fix a warning about NSScreen's +screenWithDisplayID.)

    - this stuff is highly unfinished; needs much more work and testing
    - don't be surprised if you don't see anything when trying it out, this port is basically a big reminder for me to keep working on it ;-)
    - the access module is probably going to be ported from CoreFoundation-driven C to Cocoa-based Obj-C
    - everything will be 10.4-only, since EyeTV is only available this way as well
    - the plugin to put into EyeTV is compiled in UB-mode by default and incorporates Public Domain code provided by Elgato Systems GmbH

- Remove an useless variable

- Add support for RTP padding

By the way, the MPEG-Video parser seems to ignore the MP2V specific
extra header (i.e. it passes it onto the demux instead of removing it).
Not sure if this is intended (any MPEG expert?)

Mac OS X gui: Revert [19198] (add items to the playlist in the finder's order). The finder provides elements that may be shuffled.

Mac OS X gui: Fix a rare bug of non-update of the vout's title. The manage-ing thread can't be trust on input change.

Mac OS X gui: Don't try to change the interface from a non-main thread. (Should fix a remanence bug in the controller scroll field)

May need a few more vertical spacer, after the last tab (Capture) will be added.

- control APIs: do not crash if exception parameter is null, that means caller is not interested in exceptions

Mac OS X gui: Don't yield input more than needed. (End of the set of changes that makes quitting really fast.)

- Warn that WxWidgets is deprecated.
- Fix a few Wx error messages.

Comment out a few non-thread-safe functions from embedded vout
handling. Fixes a crash when playlist item changes. refs #955
