supported video/audio formats, how to test

[Thijs van severen]

hi,

I'm having some trouble figuring out what video formats are / are not supported by Praxis

I'm guessing that Praxis supports whatever the underlying video engine/libs supports, but it would be nice to have a way to determine what does and what does not work.

Right now i just load a clip in the player, cross my fingers and hit play to see if it works.  Sometimes it works, sometimes i just get a 'internal stream error' message :-(

All hints/tips are welcome !

Grtz

Unfortunately, at the moment there's no other way to test than try
playing them. What OS are you using? If Windows, make sure that
you've installed GStreamer with the full, not typical, installation
profile; if Linux, make sure you've got the bad, ugly, etc. plugin
sets installed.

Best wishes,

Neil

Hi Neil

I'm running ubuntu 18.04 with the good, bad and ugly installed

if i open my clip in VLC it plays fine, if i use ubuntu's default video player i also get an error (this is interesting > will check further)

i tried starting praxis from terminal hoping i would get more debug/error info but that's not the case

there also doesnt seem to be a verbose switch when running from terminal

does praxis log errors like these ?

grtz

Yes, the video library used is GStreamer, the same as Ubuntu's default
video player. So on Ubuntu, PraxisLIVE should play anything that the
default video player can play.

There are other plugin sets than good, bad, ugly too - although they
should cover most bases. Worth browsing the other plugin sets -
perhaps libav plugins aren't installed and might help?

praxis or praxis_live? In the IDE, the View / IDE log should show you
all you're looking for. There is an argument for logging to the
terminal, but it doesn't by default.

IIRC looking at
https://github.com/praxis-live/praxis-live/blob/master/praxis_live.conf#L8
you should be able to use `praxis_live
-J-Dnetbeans.logger.console=true`
