[Mlt-devel] reducing xml filesizes with repetitive filters

[Mark Polesky via Mlt-devel]

Hi,

I asked this question on stackoverflow a few days ago.  Thought I'd hit up the 
mailing list to see if I might get a bite here:
https://stackoverflow.com/questions/61628423/

=

Possibly related, but separate question:

Let's say I have a file 'included.mlt':



If I want to include that file inside another, none of the usual methods seem 
to work:

1) XInclude


http://www.w3.org/2001/XInclude";>
  
  


Responds with:
Failed to load "includer.mlt"

2) external general entity



]>

  
  &included;


Responds with:
[producer_xml] parse fatal: Entity 'included' failed to parse
  row: 7  col: 13
Failed to load "includer.mlt"

Is there any way to do it?

Thanks

Re: [Mlt-devel] Problem with pango on affine transition with valign=bottom (valign=top works)

[Mark Polesky via Mlt-devel]

I am also new to melt, but It worked for me with melt 6.20.0.  You might 
consider updating.  Also, I do notice that your image is 1920x1080 (16:9) but 
your selected profile is 1440x1080 (4:3).  It's probably best to correct that 
discrepancy.

Hi all,

i have a problem using the following simple script with melt 6.6.0:

#/!/usr/bin/env bash

melt \
color:black  out=00:00:05.000 \
-track \
  title.jpg out=00:00:05.000 \
-track \
  pango: \
    text="Pango test" \
    bgcolour=0xff80 \
    fgcolour=0x00ff \
    olcolour=0x00ff \
    out=00:00:02.000 \
    size=192 \
    weight=1000 \
\
-transition mix:-1 always_active=1 a_track=0 b_track=1 sum=1  \
-transition frei0r.cairoblend a_track=0 b_track=1 disable=0 \
-transition affine valign=bottom halign=center fill=0 a_track=0 b_track=2 \
\
-profile hdv_1080_25p \
-consumer avformat:output.avi acodec=libmp3lame vcodec=libx264

It works fine with valign=top on the transition (works with -consumer sdl
as well).
With valign=bottom it works only with sdl consumer. In the above example
my output-file doesn't
contains the pango-text. The image title.jpg is 1920x1080.

I am relatively new to melt, so the transitions are copied from other
examples. What is the
problem with my approach?

Thanks for your help,
Oliver

[Mlt-devel] processing stops after 15,000 frames

[Mark Polesky via Mlt-devel]

Hi, I tried to create a minimal video 20,000 frames long (should be 11min 7sec 
at 30fps), but melt stopped processing after 14,999 frames (leaving it 8min 
20sec). Am I doing something wrong? Thanks

test.mp4:



  
  


command:
$ melt test.mlt -consumer avformat:test.mp4
