interesting use of tsmuxer, other Bluray software
by Andrew Randrianasulu 24 Dec '22

24 Dec '22

https://m.youtube.com/watch?v=76jHqjYbrbo apparently, you can "demux" srt subtitles to Blu-ray "sup" graphical subtitle stream, then edit it with bdsup2sub++ (c++/qt5 port of java-based bdsup2sup) and remux back into blu-ray! Or create dvd subtitles out of srt subtitles! Or create your your own *.ass/ssa in ageasub and then use https://github.com/Masaiki/ass2bdnxml (in theory it can give you sup file directly according to built-in help) And manipulate subtitle params with https://github.com/cubicibo/SUPer (uses python) Also, not something I tried but interesting piece of software (python again) for manipulating blu-ray internals like playlist/clip info ... https://github.com/shimamura-hougetsu/shinya Also, windows program but may work under wine? 3d (MVC) encoder (x264 can't do this) https://sites.google.com/site/videofan3d/software/frim-encoder. Also, is comment from https://www.cinelerra-gg.org/bugtracker/view.php?id=282#c3706 actually in manual somewhere? I can't see it in https://cinelerra-gg.org/download/CinelerraGG_Manual/Subtitles.html but may be it resided in some other section .... May be this advanced manipulations of Blu-ray streams also better to be put in separate html document? It really not about Cin-gg but still those pieces of info a bit hard to find so having them on our site might be attractor!

Proxy 1:1
by Andrea paz 18 Dec '22

18 Dec '22

>From an answer by IgorBeg on the forum I learn that for 1:1 proxies, if you set the "scale factor," you have double scaling: "The size of your video is scaled down of the Scale factor but, then, it is rescaled up to the project format. For example, your format project is 1920x1080 and Proxy's Scale factor is 1/4, then your videos will be scaled down to 480x270 and then up-scaled to 1920x1080. For an old computer, this option is not recommended." I put this sentence in the manual, you tell me if it is okay.

HDV with PCM audio as Blu-ray video burned to BD-RE discs
by Terje J. Hanssen 12 Dec '22

12 Dec '22

I had to troubleshoot and replace a bad SATA power connector to my internal LG Blu-ray burner that caused confusing disc mount issues and delay, before the burner device worked properly again. lsscsi | grep BD [5:0:0:0] cd/dvd HL-DT-ST BD-RE BH10LS30 1.02 /dev/sr0 So far I have tested successful burning on BD50-RE DL discs with K3b/cdrecord using a single 2GB HDV clip with PCM transcoded audio written to Blu-ray video UDF image. For HDV this time I've tested BD-RE discs from two manufacturers, Verbatim and unlabeled (dealer Slowmoose). Last year I tested also SD-Bluray video successful burned on TDK BD-RE discs. And most important, the discs starts as autoplay after loading in my Samsung UBD-K8500 Blu-ray hardware player. The quality of interlaced video and PCM audio seems for me equivalent via VLC and Samsung BD player. Testing is executed on VLC/Leap 15.4 workstation and Samsung BD-player, both connected to the same Asus 27" LCD monitor (PB2780Q), easy switchable via DP and HDMI ports respectively. To summarize and repeat procedure for this test case: > ffmpeg -i hdv01_m2t -c:v copy -c:a pcm_bluray -mpegts_m2ts_mode 1 hdv01_m2t_pcm_bluray.mts # mkudffs -b 2048 /tmp/hdv01_m2t_pcm_bluray.udfs 1126663 # mount -o loop /tmp/hdv01_m2t_pcm_bluray.udfs /mnt/test # /home/terje/mountpoint/usr/bin/bdwrite /mnt/test hdv01_m2t_pcm_bluray.mts # umount /mnt/test K3b: Burn CD-image, 2x speed (BD50-RE DL) image to burn; /tmp/hdv01_m2t_pcm_bluray.udfs (not recognizeable, but selece burn it anyway, 2-4x times) image type: Auto Burning program: cdrecord (warning to add the actual user to cdrom group) Start A question before leaving some error/warning details from various tools output/log below: Is it possible to get bdwrite to keep the original, multiple video clip names?

Is UDF 2.5 or higher really required for Blu-ray video and BD burning?
by Terje J. Hanssen 12 Dec '22

12 Dec '22

UDF is told to have replaced ISO for optical CD/DVD/BD discs. https://askanydifference.com/difference-between-udf-and-iso-with-table/ I wonder if someone can clarify if UDF version 2.5 or higher really is required for creating and burning Blu-ray video to VBD-discs. I've got this impression earlier, i.e for K3b here, which still seems to be much the case on Linux: https://bugs.kde.org/show_bug.cgi?id=257602 I've seen there could be UDF 2.5 on Ubuntu and possibly with tsMuxer(?) Bt in my case on Leap 15.4, and even on Tumbleweed, the latest available udf package versions are 2.1 and 2.3: S | Name | Type | Version | Arch | Repository ---+----------+-------+-----------------+--------+---------------- i+ | libudf0 | pakke | 2.1.0-1.27 | x86_64 | Main Repository i+ | udftools | pakke | 2.3-lp154.321.3 | x86_64 | 15.4 udftools 2.3 is even an experimental package from OBS with content /usr/bin/udfinfo /usr/bin/wrudf /usr/lib/udev/rules.d/80-pktsetup.rules /usr/sbin/mkfs.udf /usr/sbin/mkudffs /usr/sbin/pktcdvd-check /usr/sbin/pktsetup /usr/sbin/udflabel So what happends and decide the udf file system version when using mkudffs, bdwrite and dd or K3b lastly for burning? when I let K3b autodect the image (because there are no selection for UDF), it actually shows "ISO 9660" while burning. And the result has prooved to be playable Blu-ray discs in hw player.
