We need to sleep a bit before destroying the player object
because of a bug in Android in versions < 4.2.
OpenSLES is using AudioTrack for rendering the sound. AudioTrack
has a thread that pulls raw audio from the buffer queue and then
passes it forward to AudioFlinger (AudioTrack::processAudioBuffer()).
This thread is calling various callbacks on events, e.g. when
an underrun happens or to request data. OpenSLES sets this callback
on AudioTrack (audioTrack_callBack_pullFromBuffQueue() from
android_AudioPlayer.cpp). Among other things this is taking a lock
on the player interface.
Now if we destroy the player interface object, it will first of all
take the player interface lock (IObject_Destroy()). Then it destroys
the audio player instance (android_audioPlayer_destroy()) which then
calls stop() on the AudioTrack and deletes it. Now the destructor of
AudioTrack will wait until the rendering thread (AudioTrack::processAudioBuffer())
has finished.
If all this happens with bad timing it can happen that the rendering
thread is currently e.g. handling underrun but did not lock the player
interface object yet. Then destroying happens and takes the lock and waits
for the thread to finish. Then the thread tries to take the lock and waits
forever.
We wait a bit before destroying the player object to make sure that
the rendering thread finished whatever it was doing, and then stops
(note: we called gst_opensles_ringbuffer_stop() before this already).
Previously it would only work if the alpha value was in the last
component (RGBx, BGRx). Now it works wherever the alpha value may
be (xRGB, xBGR, etc).
This fixes the OSX build and any builds with --disable-egl. That issue
was introduced in "glfilter: rewrite transform_caps to preserve caps fields".

Setting a scaled factor for X coordinate is not enough as the indexer
will still think stride is shorter and will not fully skip it. Instead,
update width, so the lines are as expected. Combined with the scale, it
will hide the cropped portion.

The parsing function already frees the old value (if any), avoid a double
free by not freeing it before calling the function without setting the
pointer to NULL

The _parse_url function already frees the previous pointer, avoid
freeing it before without setting to null or we have a double free.

Refactor mssdemux to remove uridownloader to use an internal
source element which reduces startup latency and provides smaller
buffers for better buffering management downstream
Fix a regression introduced recently with the lazy init.
It was happening when calling gst_video_gl_texture_upload_meta_upload
from an aplication. So not using gst_gl_upload_perform_with_buffer.
