[erlang-questions] Real time audio transcoding with a port driver

[Kenneth Lundin]

Hi Max,

I don't know why you are thinking that this will work better in R15 than in
R16?
Can you point to any specific change in R16 that causes problems?

It has always been a bad idea to execute for a long time (before returning
to the Erlang scheduler) inside a NIF, BIF or linked in driver.

In R16B01 some BIFs and NIFs which potentially could execute for a long
time (based on the size of their input) have been made interruptible. More
specifically this concens the BIF term_to_binary and
the crypto NIFs which handle stream input.
