Have you tried using -s? It would be interesting to know, what duration your samr samples have, in order to improve the assertion. Can you send them (your files) to me?

Have you tried using -s?

yes, as i said with this parameter I can recovery video if assert is commented

Can you send them (your files) to me?

Of course videos.zip

Did anything work out?

anthwlock commented 3 years ago

The duration assertion was not the only wrong thing. As this comment says, samr samples have a size multiple of 32. In this case 128. But the "splitting" the comment refers to doen't work, often 3/4 of the sample is lost/not played correctly. However the correct size is read from the reference file, and stored in constant_size_. So one can just use that instead, see 8024f0cfbbc94c70a30004726fbfa6b23baa8b63

it works now, update windows build pls

anthwlock commented 3 years ago

windows builds are updated automagically :)

it's not working since march

It does work. What likely confuses you is that it is the (exact) same release, which gets updated on each commit. Look at Head and Date in the release message: a
