<br><font size=2 face="sans-serif">I've done some more research why the
recorded files won't play/get info on some of the tools I use.</font>
<br>
<br><font size=3>* all of the test files I made have broken mp4a atoms
(MPEG-4 AAC sample description) or ESDescriptors.<br>
* they all specify an empty IOD which means "empty MPEG-4 presentation"
(eg you see nothing). </font>
<br><font size=3>* In some files the mp4a.esds.ESDescriptor is broken:
SLConfig is included in ESD.decoderConfig when it must be in ESD. And the
ESDescriptor size is corrupted. <br>
* In some other file the entire mp4a atom is corrupted (junk data before
the esds atom)</font>
<br>
<br><font size=3>Hope this helps a bit.</font>
