Andrew,

Using the last email fix suggestion (and ignoring the previous to that email suggestion), bdwrite no longer crashes but there is an error message:

+ mount -t udf -o loop /tmp/bd_20220502-191150/bd.udfs /tmp/bd_20220502-191150/udfs
+ bdwrite /tmp/bd_20220502-191150/udfs /tmp/bd_20220502-191150/bd.m2ts
bad stream idx 2 in pgm 0
+ umount /tmp/bd_20220502-191150/udfs
+ echo To burn bluray, load writable media and run:

But unfortunately the bluray media has no audio playing which is the whole reason for choosing Truehd.  The Info Menu on the LG player reports audio type as "DD trueHD".

BTW: my linux bluray writer and the RW bluray media are often quite sketchy -- sometimes  the plug n play writer disappears and I have to reboot to get it back and I suspect the media is just getting worn after writing the same area over and over again.  Anyway that is why it takes awhile for me to respond.

actually, after making one more test it seems I can avoid fatal error (in exchange for non-fatal error) by changing bdwrite like this

Andrew, what other software has to be installed to get Truehd to work?  Andrea does not get the error I do so there must be something additional that has to be installed.  We need to know for documentation.

i tried with tsmuxer, but I guess bdwrite need some more logic to deal with it too... 

without bdwrite we do not have burnable bluray disk image, just stream alone (some modern players play those anyway..)

well, this is not exactly what we hoped for.. in this case. 

sorry TWO issues going on

1) tsmuxer choke on ffmpeg's lpcm as encoded without ONE MORE PATCH.. 

2) truehd encoder in ffmoeg may trip bdwrite... 

for truehd encoder you need to either uncomment line in bdcreate.C {with truehd profile, in /* */ pair..} or manually choose audio when batch render window come up...
