Add support for parsing AVIF still images. This patches supports
AVIF still images that have exactly 1 item (i.e.) no alpha channel.
Essentially, we will have to parse the "iloc" box and populate
the mov index.
With this patch, we can decode still AVIF images like so:
ffmpeg -i image.avif image.pn

Hi Francesco,
I think the y position of the baseline should be independent of the
content of the textfile.
For example, you might want to change the color in the middle of a text.
That can only be done by invoking drawtext two times. To make sure that
both texts share the same baseline, the wo
Hi Michael,
you're right, the default y position is not referred to the baseline but
to the upper left corner of the text. I initially referred it to the
baseline but that is not the default used by the current drawtext
filter, so I thought it would be better to keep compatibility with the

I can apply this if you confirm it works with any image size and on
unaligned data.

This patch fixes a wrong type of BTI landing pad when branching to
functions instantiated via the fft*_neon macro.
Although the previously employed paciasp instruction serves as a landing
pad, for the ways that this function is invoked it is the wrong type.

Hi Francesco,
in my opinion the line spacing looks good. But there is still the
problem that the y position of the baseline depends on the height of the
characters in the first line. You see that when you switch between your
pictures line_height_net_arial.png and line_height_new_arial2.png.

Hello ffmpeg team,
I'm working on an enhanced version of the drawtext filter and would like
to discuss with you about a minor change in its behavior related to line
spacing management.
In the current implementation the space between two lines of text is set
equal to the height of the highest g

Hi,
Is anyone interested in this patch? This makes AVX2 hscale work on all
input sizes.
Thanks,
