The state of blu-ray burning in linux is terrible

Hi,

Source code and man page of cdrskin indicate that a burn
run on BD-R has a transfer chunk size of 32 KiB if not
- option stream_recording=on is given
- or option dvd_obs=64k is given
- or ./configure option --enable-dvd-obs-64k was given at build time

So the lower performance of cdrskin compared to cdrecord might
come from an unnecessarily high number of SCSI transactions.

I am not aware whether cdrecord uses 64 KiB write transactions
with BD-R. But in any case it seems worth a try to let cdrskin
write with 64 Kib.
So Richard, if i can have a test run with your next regular BD-R
burn ... :)

BTW: How far did you get with playing back your video ?

Yesterday it was announced that Brasero has got a maintainer:
