<p>Hi Michael !</p>
<p>Yes, thanks for this reminder !</p>
<p>I was just hoping to play any file with uridecodebin (with a
specific property) like filesrc. But it is not possible.</p>
<p>The idea was to generate a "moving noise" in the time...</p>
<p>++</p>

Hello Jack
<div class=""><br class="">
</div>
<div class="">I don’t know your exact use case, but if you are
looking for a way to generate noise you may want to take a look
at audiotestsrc. It as a few noise models you might find useful:</div>
<div class=""><br class="">
</div>
<div class="">
<div class=""> wave : Oscillator waveform</div>
<div class=""> flags: readable, writable,
controllable</div>
<div class=""> Enum "GstAudioTestSrcWave"
Default: 0, "sine"</div>
<div class=""> (0): sine -
Sine</div>
<div class=""> (1): square -
Square</div>
<div class=""> (2): saw -
Saw</div>
<div class=""> (3): triangle -
Triangle</div>
<div class=""> (4): silence -
Silence</div>
<div class=""><b class=""> (5):
white-noise - White uniform noise</b></div>
<div class=""><b class=""> (6):
pink-noise - Pink noise</b></div>
<div class=""> (7): sine-table -
Sine table</div>
<div class=""> (8): ticks -
Periodic Ticks</div>
<div class=""><b class=""> (9):
gaussian-noise - White Gaussian noise</b></div>
<div class=""><b class=""> (10):
red-noise - Red (brownian) noise</b></div>
<div class=""><b class=""> (11):
blue-noise - Blue noise</b></div>
<div class=""><b class=""> (12):
violet-noise - Violet noise</b></div>

<div class="">Hi,<br class="">
<br class="">
<blockquote type="cite" class="">I'm not an expert in
uridecodebin, but from the tests I've<br class="">

<br class="">
That's right.<br class="">
<br class="">
Decodebin needs to be able to "typefind" a stream, and
it will then try<br class="">
and plug the right parsers/decoders for the format the
file is in.<br class="">
<br class="">
You want to do the exact opposite, so decodebin is not
really suitable<br class="">
for this use case, and I'm not sure what it would buy
you here either.<br class="">
<br class="">
Cheers<br class="">
