Pipeline serialisation to and from XML is horribly broken for all
but the most simple use cases, and will likely never be fixed.
Make sure everyone playing around with these tools is aware of
this, to avoid frustration. See countless bug reports in bugzilla.
g_setprgname is implicitly called by g_option_context_new() with a check
to see if it's been set already, so set it before g_option_context_new()
Move version printing back until after the options have been parsed,
otherwise it won't work, since it evaluates a flag set by the
option parser.
Check if we've been interrupted only four times per second instead
of twenty times per second, to wake up the cpu less often and
save power (see bug #600922).
Revisit these strings now that the change regarding the message source
object in gst_element_found_tags_for_pad() got reverted. Try to refer
explicitly to what kind of element it is (element, pad, etc.) in some
cases, which is nicer than having to deduce this info (and we can
re-use the already existing translated strings for the most common
case). It also makes for better example code, since it's clear now
that the message source object doesn't have to be an element.
When it is shutting down a pipeline after ctrl-c, set pipeline to
paused before waiting for the main loop to complete all pending
transactions. Fixes#584657.
If some part of the pipeline is generating signals or idle functions
at a fast rate, waiting for a main loop iteration may never return.
Disable the handling of the CLOCK_LOST messages until we fixed and released the
elements (rtspsrc) that break when we quickly PAUSE/PLAY the pipeline.
Fixes#579127
We should use GLib's g_print*() functions for printing stuff in gst-launch, not printf and friends, since we're printing
translated strings, which we get in UTF-8 encoding, and GLib's print functions expect UTF-8 encoded strings whereas printf
et al. expect strings in the locale encoding, which may or may not be UTF-8.
Also add a PRINT convenience macro so we don't have to litter the code with if (!quiet) statements.
Add a GST_MESSAGE_REQUEST_STATE that can be posted by element when they would
like to have the application change the state of the pipeline. the primary use
case is to pause the pipeline when an audio mixer is mixing a higher priority
stream but it can also be used for other purposes.
Add some docs and a unit test.
Implement the REQUEST_STATE message in gst-launch.

Make sure that we actually show the important message part of a

No need to check if the gerror is not NULL to free; first of all
g_free accepts NULL; and second the default error handler would
segfault if gerror was NULL.

If the top-level of the parse is a normal bin, it doesn't do the

to notify the fact that an element changed state in a streaming

STATE_DIRTY message instead of abusing a boolean in a STATE_CHANGE
message.

_add_watch() and _add_watch_full() now take a MessageType mask to

_poll() returns the GstMessage instead of the message type to avoid
race conditions.
_have_pending() takes a MessageType mask now too.
Added testsuite for multiple bus watches.
