BD subtitles <> dvd subtitles
by Andrew Randrianasulu 10 Dec '21

>From what I remember CinGG can create dvd subtitles but not BD (bluray) subtitles. May be this project can convert them (qt5, meson) ? https://aur.archlinux.org/packages/bdsup2subpp-git/ slightly older src with appimage https://github.com/amichaeltm/BDSup2SubPlusPlus original java-based tool https://github.com/mjuhasz/BDSup2Sub description === BDSup2Sub A tool to convert and tweak bitmap based subtitle streams BDSup2Sub is a tool initially created to convert captions demuxed from a Blu-Ray transport stream (M2TS) into the DVD VobSub format (SUB/IDX) used by many DVD authoring tools - hence the name. Many more features were added over time as was support for other formats. So in the meantime the name seems a little inappropriate. In a nutshell, it's a subtitle conversion tool for image based stream formats with scaling capabilities and some other nice features. Supported Formats Blu-Ray SUP Sony BDN XML (as used by Sonic Scenarist HDMV) HD-DVD SUP (import only) VobSub (SUB/IDX) DVD-SUP (SUP/IFO) What it can do convert any supported import format to any supported export format add a fixed delay to all timestamps perform a frame rate conversion e.g. for pal speedup synchronize time stamps to output frame rate edit times and position of each caption control all features (except editing) from the command line move all captions inside or outside a given area or horizontally crop the target screen size scale up/down with a variety of filters (from bilinear over bicubic to Lanczos3 and Mitchell) edit "forced" flags exclude single captions from export erase rectangular regions of a caption scale captions independently of screen size automatically remove fade in/out from imported subtitle streams. export the target palette in PGCEdit text format (RGB values 0..255) edit the imported DVD palette when input is either VobSub or SUP/IFO edit the frame palette and alpha values when input is either VobSub or SUP/IFO set/clear forced flags for all captions What it can't do BDSup2Sub only supports image based subtitle streams. ==== so.. in theory CinGG's subtitle output can me MicroDVD'S .udvd but then making those into graphical dvd subtitles will require ffmpeg called with right params I found this post converting DVB subtitles to DVD subtitles inside mkv and also image of titular bdsup2sub https://forum.videohelp.com/threads/386350-reencoding- dvbsub-to-dvdsub-using-ffmpeg Subtitle options: -s size set frame size (WxH or abbreviation) -sn disable subtitle -scodec codec force subtitle codec ('copy' to copy stream) -stag fourcc/tag force subtitle tag/fourcc -fix_sub_duration fix subtitles duration -canvas_size size set canvas size (WxH or abbreviation) -spre preset set the subtitle options to the indicated preset https://trac.ffmpeg.org/wiki/HowToConvertSubtitleToASS ..S... = Subtitle codec DES ass Advanced SubStation Alpha subtitle DES dvbsub DVB subtitles DES dvdsub DVD subtitles D S microdvd MicroDVD subtitle D S pgssub HDMV Presentation Graphic Stream subtitles DES srt SubRip subtitle DES xsub DivX subtitles (XSUB) for me system ffmpeg output (4.4) DES... ass ASS (Advanced SSA) subtitle (decoders: ssa ass ) (encoders: ssa ass ) DES... dvb_subtitle DVB subtitles (decoders: dvbsub ) (encoders: dvbsub ) DES... dvd_subtitle DVD subtitles (decoders: dvdsub ) (encoders: dvdsub ) D.S... hdmv_pgs_subtitle HDMV Presentation Graphic Stream subtitles (decoders: pgssub ) ..S... hdmv_text_subtitle HDMV Text subtitle D.S... jacosub JACOsub subtitle D.S... microdvd MicroDVD subtitle D.S... mpl2 MPL2 subtitle D.S... pjs PJS (Phoenix Japanimation Society) subtitle D.S... realtext RealText subtitle D.S... sami SAMI subtitle ..S... srt SubRip subtitle with embedded timing ..S... ssa SSA (SubStation Alpha) subtitle D.S... stl Spruce subtitle format DES... subrip SubRip subtitle (decoders: srt subrip ) (encoders: srt subrip ) D.S... subviewer SubViewer subtitle D.S... subviewer1 SubViewer v1 subtitle D.S... vplayer VPlayer subtitle DES... webvtt WebVTT subtitle $ so in theory chain should be : CINGG > udvd /MicroDVD output - > ffmpeg - > dvd subtitles - > BDsup2sub - -> tsmuxer (as PGS stream) (or I found old message saying bdwrite can mux BD subtitles, just there was no more notes about this) https://lists.cinelerra-cv.org/pipermail/cinelerra/2017q1/005829.html Again, our subtitles section a bit bare, may be someone can try said tools and write a bit more on gotchas encountered... And still, Andrea/Phyllis I sort of insist on adding at least few lines about mp4box and tsmuxer alternative muxers (may be to newly added Codecs and Formats?) because this info (if you are not seasoned video enthusiast) a bit hard to find.. I was making circles around this topic for nearly year! A lot of windows programs, or specialized editors like https://github.com/hguandl/ass2bdnxml with source but require some windows version of avisynth (avisynth+ available for linux, but apparently this tool input module based on much older x264 avisynth input! so no linux...) https://github.com/magiruuvelvet/jimaku-editor/blob/master/pgs-encoder/main… mostly concerned with Japanese/Chinese graphical subtitles.. and whole encoder probably was developed back in 2009 by some user who badly needed those graphical subtitles

lpcm for bluray hacks!
by Andrew Randrianasulu 09 Dec '21

So, this time I tried to integrate encoder I was talking about earlier into Cingg. files for git am it... initiializes, and then famous for me android/termux audio crash comes... Terje, Andrea - you can try it even with stereo (but high bit depth/high freq) audio tracks... after hopefully successfull rebuild (encoder added to our ffmpeg copy, so rebuild) select ffmpeg > m2ts, and for audio m2ts_pcm.m2ts try render, and listen to resulting m2ts file with mpv or vlc. or even try to burn it into real bd disk..

New AppImage release with mostly only changes for Android/Termux builds
by Phyllis Smith 07 Dec '21

07 Dec '21

The November AppImage is available now in the usual place along with the updated releasenotes, pdf manual, and html manual. https://cinelerra-gg.org/download/images/CinGG-20211130-x86_64.AppImage https://cinelerra-gg.org/download/images/CinGG-20211130-multibit.AppImage https://cinelerra-gg.org/download/images/CinGG-20211130-x86_64-older_distro… https://cinelerra-gg.org/download/images/CinGG-20211130-i386.AppImage I am still trying to come up with a solution for 32-bit AppImage on Debian 11 Bullseye, but I think we do not currently have the expertise to fix this. I was able to get it to build/compile on 11 but it just SEGV's when loading and even just clicking on OK in a menu. *Very sketchy notes on doing a build for an Android tablet/phone are at:* https://cinelerra-gg.org/download/CinelerraGG_Manual/Android_Tablet_or_Phon… Need Andrew and Andrea to read this over and fix it. ****************** Copy of latest Release Notes GIT for Cinelerra-GG has the following changes from 11/01/2021-11/30/2021 *Libaom *has been upgraded to 3.2.0 with speed improvements. - 20% faster on a 1.5 minute video. *Elive* has provided packages to install for both the version 10 Buster and version 11 Bullseye *Debian*. The wikipedia entry for Cinelerra now has a *Hungarian translation* thanks to *MatN* and assists. *Mpeg render formats* added from Andrew to include mpeg2_hq.mpeg, pass1/2of2.mpeg. The availability of *CinGG on an Android* tablet using Termux has been proven with a variety of mods prepared by *Andrew-R*: - new file blds/termux.bld to use as a guide for building CinGG - new files bthread.h and libbthread.tar.gz for Android specific code - various patches of ifdefs to avoid compiling sections of code that will not work on the Android in libaom, libwebp, libzmpeg, ffmpeg4.4, mjpegtools, compiling DB (database) for x86 and i386 only, guicast directory file mods, Makefiles/configure.ac changesand various other small mods.

pcm bluray encoding
by Andrew Randrianasulu 07 Dec '21

07 Dec '21

Thanks to Paul (who wrote a lot of ffmpeg code) I hacked this patch against ffmpeg-4.4. Can anyone test how it work with 5.1 and stereo sounds (s16, s24 broken ATM), especially if it remaps 5.1 channels correctly? I tested like this: $ ./ffmpeg -i ~/matrixbench_highdivx_ac3.avi -c:v libx264 -s 160x120 -c:a pcm_bluray -mpegts_m2ts_mode 1 -sample_fmt s16 1.m2ts mpv 1.m2ts but my tablet sound definitely not 5.1! NOTE: this is not yet cinelerra-gg patch, just something I test with our version of ffmpeg

Blu-ray compliant MPEG-2 SD video with LPCM audio
by Terje J. Hanssen 06 Dec '21

06 Dec '21

The source video files I want to convert to Blu-ray compliant MPEG-2 SD video with LPCM audio are: 1) DV25.dv, 720 x 576 (PAL), 50i 4:2:0 video with LPCM stereo audio and 2) SD ProRes.mov, 422 (HQ) 19-bit video with LPCM stereo audio The purpose is to get better MPEG-2 quality using higher (highest) possible bitrate than for DVD video. (Yes, I have tested h.264 via Cin-GG) Here a sample ffmpeg command script found for HD video with PCM (Blu-ray not mentioned): https://gist.github.com/avoidik/153879c06afdcaad8d69b38bcc00abb7 # with PCM 16-bit audio (uncompressed), constant video bitrate with specific bitrate tolerance ffmpeg -i "input.mp4" \ -c:v mpeg2video -pix_fmt yuv422p -refs 1 -bf 2 -b:v 50M -maxrate 50M -minrate 50M \ -s 1920x1080 -aspect 16:9 \ -c:a pcm_s16be -f vob \ "output.mpg" Suggestion to FFMpeg command to convert the actual SD video files Blu-ray compat? And if PCM has to be muxed via MP4(Box) first, a guideline is welcome? ------------------ Some Blu-ray technical info and specifications: Video codec MPEG2 - MP@ML (4:3 or 16:9), MP@HL (16:9) Video frame size 720×576 25 frames interlaced / 50 fields (4:3/16:9) Max video bitrate 40 Mbit/s **BD-R/RE AV SESF, Part 3 (2018): Video Streams: max. 15 Mbps VBR (MP@ML) and 24 Mbps (MP@HL) Audio codecs LCM 1.536 Mbps (16 bit, 2 ch), 2.304 Mbps (20, 24 bit) ----------------------- Terje J.
