[FFmpeg-devel] lame: output buffer too small issue

[Dennis Volodomanov]

Hello all,

This problem started to occur only recently (within the past 2-3 weeks),
basically lame reports an error and the whole file is not encoded
properly.

The output is like this:

Can anyone tell me what's wrong and how to fix this issue?

Thanks in advance!
