By adding extra codecs after the official distro installation:
ffmpeg -v quiet -codecs | grep aac
DEAIL. aac AAC (Advanced Audio Coding) (decoders: aac
aac_fixed libfdk_aac ) (encoders: aac libfdk_aac )
D.AIL. aac_latm AAC LATM (Advanced Audio Coding LATM syntax)
I saw (I didn't know!) that the h264.mp4 (audio) preset uses the aac
codec. So CinGG already offers the possibility to render in aac. Maybe
it's better to change the name to "aac.mp4". I tried, but putting aac
in the name leads to a different "samples" option (s16 instead of
fltp) and it doesn't work. probably we should use the "libfdk_aac"
codec instead of just "aac" (which I don't know what it is and how it
works!). But this is not recognized because, i guess, thirdparty's
ffmpeg is not compiled with the option for aac audio.

I think I have tested both methods, mostly in 2016/2017, and just a
few later. (Beside I have digitized several analog S-video to DV
video files and recorded them to BD-R data discs as backup. I have at
least 20-30 of each Hi8 and HDV tapes left).
So let me understand the workflow:
1- import the DV files into the PC with firewire (what do you use?)
Well, I do an attempt:
Analog Hi8 S-Video S-Video
tape player ------------> TBC -----------> A/D-conv.
(1992) + DV/HDV HDD
Firewire PC
Firewire rec/player
------------> DV/M2T
HDV tape player --------->
(2007)
The A/D converter is built-in the stand-alone DV/HDV HDD recorder/player
device is connected with Firewire and mounted on Linux fs file copying
similar like an external harddisk.

With digital DV or HDV tape camcorder/players only, the most usual on
Linux has been to connect players via firewire directly to PC firewire
port, and use 'dvgrab' on Linux to capture files from tape.

--------------------
2- Create a new project in CinGG using the DV/HDV presets.
3- Upload the files to CinGG.
4- Use "Create BD" for BD authoring
I don't think it matters, but we probably used Batch render with m2ts
https://cinelerra-gg.org/download/CinelerraGG_Manual/DVD_Bluray_Creation.html
5- Burn the structured files to a BD-R disc (directly from CinGG or
outside of it?).
Is this correct?
Thanks for all this info on topics I didn't know about!
The procedure as described in the manual section above, includes also to
create a file system dependent of the disc type, BD-R (growiso) or BD-RW
(preformat + udfs)
-------------
Possibly Phyllis can confirm if a summary 'Create BD procedure' will be
similar to the related 'HDV to Blu-ray' procedure as follows?

HDV on a Blu-ray Disc Without Re-encoding
An MTS file is a video file saved in the high-definition (HD) MPEG
Transport Stream video format, commonly called AVCHD. It contains HD
video compatible with Blu-ray disc format and is based on the MPEG-2
transport stream. MTS files are often used by Sony, Panasonic, Canon and
other HD camcorders. Legal input for Video – MPEG1VIDEO, MPEG2VIDEO,
H264; Audio – MP1, MP2, AC3, AC3PLUS, DTS, TRUHD.
For creating a blu-ray disc, if you have HDV MPEG-2 media that is in
blu-ray format, you can save the original quality of your work, rather
than rendering it to another format. Follow the steps below directly
instead of going through CINELERRA-GG. It has been tested on 10
different MTS files.
du -sb /yourHDVfile.MTS # Determine the size of your file in bytes.
blocks=((size-in-bytes/2048 + 4096)) # Convert bytes into blocks + a
little more.
mkudffs /tmp/newfilename.udfs blocks # Create a file with that \# of
blocks + some extra.
mount -o loop /tmp/newfilename.udfs /mntX # Use a mount point
like mntX that is not in use.
/<cinelerra_installed_path>/bin/bdwrite /mntX /tmp/yourHDVfile.MTS #
Substitute \CGG{} path.
umount /mntX # You must unmount the udfs filesystem
growisofs -Z /dev/bd=/tmp/newfilename.udfs # Replace /dev/bd with your
bluray hardware device.
OR dd if=/tmp/newfilename.udfs of=/dev/bd bs=2048000 # if using
rewritable blu-ray; replace bd.
