Ok, here it is. It has took a bit longer than expected due to
ever-standing real life work issues and due to needed refactoring that
this task has pulled in. Anyway.
filter_astat in CVS HEAD (should) can now detect if an audio track is
silence only.
Just use
transcode -i file -a X -J astat
Euhrystic implemented is a bit harsh, maybe it still needs some
extensions/tuning. Can't do it now, but It's planned before 1.1.0
released. Feedback very-welcome.
filter_detectsilence can do a stuff like that as well, but is
trickier. In practice, filter_detectsilence really detects the silence
*intervals* between audio chunks (useful to separate songs or track
parts, for example). Of course, if a silence interval is very long,
one can assume that the whole audio track is silence only, but isn't
so straightforward.
I think the best way is to extend further filter_astat, and that's the
way I will go.
None of those features will be backported to 1.0.x in any foreseable
future.
I'm sorry for that, but that is due ever-standind time lacking.
Anyway, patches welcome. ;)
By the way, I'm using the freshrpms version of transcode. I couldn't get
1.0.3 to compile on my machine.
It would nice to see the errors; start a new thread if you like.
Bests,
I tried 'transcode -i soundtest2.mp3 -a X -J astat' on one of my files
and got an error:
[EMAIL PROTECTED] transcode]# transcode -i soundtest2.mp3 -a X -J astat

[transcode] critical: invalid parameter for option -a
Again, I'm a total stranger to transcode. Can you tell me what configure
options I should be using (if any) to make this work?
Also, in a later post, you mentioned using filter_detectsilence instead
of astat. Which should I use? If detectsilence, then how?

(This is all on the latest CVS HEAD copy of transcode. I was finally
able to get it to compile.)
