[Lazarus] How to use RunCommandIndir() in a thread?

[Michael Thompson]

G'day,

Sorry for not replying earlier, I'm under the pump at work.

I run multiple ffprobe calls, each in their own thread.  I can report there
is no problem.  So ffprobe itself is threadsafe.  I also use a (Lazarus)
app called dmMediaConverter that calls ffmpeg in threads to convert video,
so again ffmpeg is threadsafe.

I use TProcess directly.  It will be a day or two, but I can flick you
through the code that sets up my TProcess, and I put together something on
my thread logic.

I can tell you that I have only ever written one threaded app in my life -
and that was to thread ffprobe.  The whole thing was much easier to develop
than I thought.  For resources I used the wiki, but mainly the Example
Programs that ship with Lazarus.

Apologies for the lack of actual info here.

Mike
