callback "New-sample"

[Armin Erkert]

Hello Michael,

I have already set the "emit-signal" to true

g_object_set (app->sink, "emit-signals", TRUE, NULL);
g_signal_connect (app->sink, "new-sample", G_CALLBACK (new_sample), app);

but the callback "new-sample" is retrieved several 100th times only  
after I have pushed all images into the stream.

Have now seen that in the \tmp\ a temporary file qtmuxXXXXX is  
created, and suspect that qtmux first caches everything ....

Regards
Armin
