.. or turn the overlay off by setting alpha to 0.0

... such as a frame header parsing throwing some suspicious warnings.
So we can be a bit more convinced we determine the right frame end.

... which is particularly useful if locked on to the wrong frame start
and/or corrupt frame being crc checked.

ignoring some transient ones.

Somewhat at least. No idea why it doesn't pick up the description
or example pipeline.

Still lacks features such as positioning or resizing, or
animations, but it's usable already, and supports lots of
formats.

This allows outputting streams in AVC format even if the SPS/PPS are sent inside
the RTP stream.

Add support for direct encoding of 8- and 16-bit big endian gray images.

https://bugzilla.gnome.org/show_bug.cgi?id=672025

Since this is what the command line tool does as well, it seems like
a better default.

This fixes the mutex being unlocked too much and ending up allowing
other threads when they should not.

pngdec can now decode gray 8- and 16-bit images without alpha channel
direct to video/x-raw-gray format. 16-bit gray images have big-endian
format, because it's native PNG endianness. Gray images with alpha
channel still converted to RGBA.

No need to include the int main () { } bits, the body is enough.

... so as to ensure these to be handled and sent at proper time.

This variable can never be below zero anyway.

This was an actual bug as it could've caused reading from
invalid memory areas when the input is broken.

The base class may have set the DISCONT flag on the first buffer pushed
out. We need to clear that when recycling buffers back into the buffer
pool, otherwise we constantly push out buffers with the discont flag
set, which might upset downstream elements, esp. for compressed
formats like mpeg-ts.

Make sure we always call munmap() with the same size we called mmap()
with before.

Current v4l2src uses the same structure for VIDIOC_QUERYBUF, VIDIOC_QBUF
and v4l2_munmap calls. The problem is that the video buffer size (length)
may vary for compressed or emulated bufs. VIDIOC_QBUF will change it if
we pass the pointer of a v4l2_buffer. This is why we should avoid using
same variable for mmap and video buffers.

... which does not allow expressing arbitrary depth in a GstAudioFormat.

Also adjust unit test to modified behaviour.
