rate_init: Assertion `factor > 0' failed #7
Description
I've just started using your package. To be honest I have no idea about sox, it's the first I've heard of it.
I have it installed anyway but I am getting an error when running either:
$waveform->getWaveformData($width)
or
$success = $waveform->getWaveform('thumbnail.png', 1024, 512);
Fatal error: Uncaught Exception: Failed to run sox command. Error: sox: rate.c:303: rate_init: Assertion 'factor > 0' failed. Aborted (core dumped) in /vendor/maximal/audio-waveform/Waveform.php on line 256
The error occurs on both local and remote mp3 files.
On further inspection it seems to be a 'Division by zero' problem, caused here (line 197):
$needRate = 1.0 * $width * $samplesPerPixel * $this->getSampleRate() / $this->getSamples();
$this->getSamples() seems to be returning null and I might have narrowed it down further to (line 67):
if (preg_match('/Duration.*[^\d](\d+)\s*samples?/ui', $str, $match))
There doesn't seem to be a 'Duration samples' line in my sox output
