[vlc-devel] On-the-fly AR change from decoder

[Marian Ďurkovič]

Hi all,

  please find below the "proof of concept" patch for on-the-fly AR change
triggered by the decoder. It lacks a lot of stuff - but it's only meant
to demonstrate it can work. Obviously, it avoids crash on AR change.


   With kind regards,

        M.
