[vlc-devel] Adding logo filter now restarts vout in 1.1.2

[Jacques Boileau]

Hi,

For those following this thread and have the same problem, here is a
way I have found to circumvent the problem while a permanent fix is
available:

1. Do not use the logo enable/disable API so vout won't be restarted.
2. When creating a libvlc instance using libvlc_new, pass the
following option: "--sub-filter=logo". This will enable the logo
filter but no logo will be shown since none is provided yet.
3. You can use the rest of the logo API to set file, position etc.
when you need to show a logo.
4. Use the logo opacity instead of the provided enable/disable API if
you need to enable/disable the logo. Opacity=0 will hide the logo
(disable) and Opacity=255 or what you want, will show it (enable).
