Thanks again a lot Dan !
Last question : is it possible to force the Webvfx producer to render the
web page at a specific width/height, different from the profile
width/height ?
The idea is to generate a HTML page with a fixed width/height (like 1920 x
1080), independently of the video output (which may be 1280 x 720 for
instance).
On the following output profile
frame_rate_num=25
frame_rate_den=1
width=1280
height=720
progressive=0
sample_aspect_num=1
sample_aspect_den=1
display_aspect_num=16
display_aspect_den=9
colorspace=709
I tried adding the following producer
<producer id="1">
<property name="mlt_service">webvfx</property>
<property name="resource">plain:index.html</property>
<property name="transparent">1</property>
<property name="meta.media.width">1920</property>
<property name="meta.media.height">1080</property>
</producer>
but it crashes melt (core dump). It works without "meta.media.width" and
"meta.media.height" but the HTML page generated is 1280x720
Have a nice week-end,
Geoffroy
