Data chunk size is zero #
|Problem ID||Manufacturer||Affected Firmware||Fixed in firmware||Affected Hardware||Status|
We’ve been given a sample of a file that is from a FL sensor but that has a
data chunk value of
Additionally, the RIFF chunk size is
Otherwise the file seems to be fine - there seems to be valid samples right through the file (not typical

Fail to read the files - after reading 0 for data chunk size the tools infer 0 samples and don’t/can’t process any data.
ffprobe can ignore the bad chunk size and estimate the duration of the file.
sox does not report the duration.
