I added the shortcut 'm' in nvlc for toggle mute. The volume status is
replaced my 'Mute' when enabled.

I also remapped the shortcut of metadata box from 'm' to 'M', I think
it follows the principle of least surprise.

When an output picure is requested from a Samsung (exynos?) device
it is not guarateed to be aligned to 128 bit (4 pixels).

We want to center the subpicture region, but the text itself needs
to be rendered left justified in order to get consistent placement
of captions (e.g. indentation).

Introduce a new alignment type which centers the subpicture, but
not the text it contains within (and enable it for the EIA-608 decoder).

In order to get consistent EIA-608 caption positioning, we need to be able
to size the fonts based on the size of the video.  Add support for
specifying the font height as a percentage of the video.

We need to add quotes to the color attribute for the font tag, or else
the XML parser will choke and the HTML will not be rendered.

Make the buffer larger, since there are more HTML tags in the resulting output
stream.

If the character in the EIA-608 stream is one of the reserved characters,
escape it accordingly so that the HTML renders properly.

If there are any whitespace characters before the start of text in a row,
convert it to non-breaking whitespace. We do this because the RenderHtml
function will strip any cases of more than one contigious whitespace. The
effect of such is that text that is not left justified will be forced to
the left.

Because the subpicture field contains all the lines, we need to change the
layout.

We need to render all the rows, or else the placement of popup captions will
not be correct.

The previous code worked fine when rendering text horizontally aligned at the
bottom of the screen, but won't work for a real layout.

We need to use the HTML renderer if we want colors/styles to work

According to Qt, props must have a read method

And more :)

hack adapted from the qt interface.

close #7876

avcodec contains codecs that don't like variable size frames, so feed
avcodec with frame_size chunks and and handle leftovers ourself. This
functionality was dropped when flushing was introduced and seemed to
work without just fine, I was proven wrong.

avcodec: aout_BitsPerSample uses  vlc_fourcc_GetCodec itself, so no need to call it ourselves in here

Doing it in the callback cause deadlocks.

It seems that standard OpenGL 2.0 requires version number to be equal to 120 contrary to OpenGL ES 2.0 that requires it to be equal to 100.
