udfclient 0.8.11 patch testing?
by Andrew Randrianasulu 29 Nov '21

29 Nov '21

udfclient is suite of udf-related utils developed for NetBSD Available for debian-based distros and arch, but notably not for rpm-based distros according to https://repology.org/project/udfclient/versions can you download orig. tarball and patch it with attached patch and try to './configure / make' it on Linux box with normal {for us} gnu make? And run resulted udfclient from build dir? ./udfclient file.img (-W for writing) Also, can you try to compile my hack on newfs_udf from NetBSD current? just make in source tree.. might fail due to no configure at all. this is slightly different newfs_udf command, creates udf up to maximum revision 2.60 (with some limitations). My hack most likely will not work directly on optical drive - but it worked for me on small image file. Can you test it on large file too? both hacks already on my github (but I am not sure I uploaded files correctly via their webinterface)

udf verifier
by Andrew Randrianasulu 27 Nov '21

27 Nov '21

Can anyone try to test bdwrite's output with this tool: https://www.lscdweb.com/registered/udf_verifier.html for Netbsd created 2.50 udf on hard drive file it requires -blocksize 512, but for real bluray image blocksize must be 2048 (default) $ ./udf_test -blocksize 512 ~/udfimg.img > log there is linux (386) binary, but of course I compiled it anew, on termux. no scsi support, but othervise seems to work

Testing HDV on a Blu-ray Disc Without Re-encoding
by Terje J. Hanssen 26 Nov '21

26 Nov '21

I pick up again and continue another thread on this topic started a year ago: https://www.mail-archive.com/[email protected]/msg02145.html In this post I start carefully with three questions regarding manual definitions and procedure in this section: https://cinelerra-gg.org/download/CinelerraGG_Manual/HDV_on_Blu_ray_Disc_Wi… > 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. ========== Q1. My HDV 1080i video file transfered from tape to HDD via Firewire, get a file extension M2T, which then is recognized as format MPEG-TS by Mediainfo. AFAIK the next generation camcorders after HDV used H.264/AVC (AVCHD)? ========= > Legal input for > Video – MPEG1VIDEO, MPEG2VIDEO, H264; > Audio – MP1, MP2, AC3, AC3PLUS, DTS, TRUHD. To verify this with FFMpeg for the previous HDV test-file "20081103140154.m2t" available on internet: ffmpeg -i 20081103140154.m2t 2>&1 >/dev/null | egrep "Audio|Video" Stream #0:0[0x810]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv, bt709, top first), 1440x1080 [SAR 4:3 DAR 16:9], 25000 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc Stream #0:1[0x814]: Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, fltp, 384 kb/s According to the manual, both the HDV MPEG2Video stream and MP2 audio stream should be legal input to create a Blu-ray disc. However, MP2 isn't on Sony's list or other I have seen over audio and video codecs supported on Blu-ray Disc media. https://www.sony.com/electronics/support/articles/00029663 Q2. Can someone clarify if MP2 rather should be transcoded to i.e AC3 instead, possibly also remux to BDAV/M2TS if required (below)? (On my first attempt with "MTS" format, Mediainfo reported this FileExtension_Invalid: ts m2t m2s m4t m4s tmf ts tp trp ty) ========= Q3. I also wonder if the manual command procedure creates a BDAV or a BDM structure, and optional if a DVD-RW disc can be used to create and playback this "Blu-ray disc" using a Blu-ray burner and a standalone UHD-Blu-ray player device? (At the time I have no free BD-R/RE discs left) ========= Transcode to AC3 and remux to M2TS with FFMpeg if required: ffmpeg -i 20081103140154.m2t -acodec ac3 -vcodec copy 20081103140154.m2ts ffmpeg -i 20081103140154_m2t-ac3.m2ts 2>&1 >/dev/null | egrep "Audio|Video" .........

Fwd: arm/termux series (possibly broken on x86)
by Phyllis Smith 25 Nov '21

25 Nov '21

Checked into GIT, additional TERMUX/ANDROID patch related to mjpegtools + the libwebp patch3 from the other day. This takes care of randrik19 -- 0012, 0020, 0035, and 0054. Andrea, could you build because the libwebp patch is in too and just run a couple of videos through? Andrew, could you verify checkin? Next working on the libbthread mods (Andrew, thanks for the latest releated email on these).

truehd patches from ffmpeg git
by Andrew Randrianasulu 24 Nov '21

24 Nov '21

so.. patches mostly applicable to ffmpeg-4.4 while I slightly edited 'last frame' fix due to other ffmpeg changes apply 'last frame' and '24-bit' for encoding truehd hopefully lossless apply two mlpdec patches for more correct decoder flush/crc check try to apply mlp.h and libavformat patches for timestamps in demuxer... stop-returning-empty for mlpenc not tested. after all this patching both ffmpeg and cin should work better with truehd streams (still require 'strict -2' in profile) there were other fixes and code movements but i hope those patches can fix real bugs and allow losless re-encoding between pcm and truehd (check crc's!)

ffmpeg's e-ac3 encoder
by Andrew Randrianasulu 24 Nov '21

24 Nov '21

according to some tests it works, but some hw decoders (in tv) migh refuse stream ( https://www.reddit.com/r/ffmpeg/comments/k3z9i9/how_bad_is_ffmpegs_eac3_enc… it also does not support more than 6 channels https://trac.ffmpeg.org/ticket/3595?cversion=0&cnum_hist=7 command line and bitrates possible here: https://ffmpeg-user.ffmpeg.narkive.com/JJ0ohMKA/eac3-encoding -acodec eac3, up to 6 mbps... testing should be as simple as copying ffmpeg/audio ac3 profile with new name and replacing ac3 with eac3

Formats and Codecs in CinGG
by Andrea paz 22 Nov '21

22 Nov '21

I present a first draft to create Appendix section about formats and codecs supported by CinGG. I don't know DV; DVD; BLU RAY and RAW formats. If anyone uses them and can provide better info, it would be my pleasure. Also the info on MOV as a good format for editing I have only read and not understood well. Are they correct? Corrections, additions and advice are welcome. The bigger question is: is it worth stretching the already big manual with this section? [NOTE: is not what Terje requested; I'm not sure how to implement those tables. If you can write them, then I'll transpose them into Latex...]

That will hopefully fix the "cannot build" error. try to study attached patch I made as part of effort to build Cin on elbrus machine. there was plenty of places where autoreconf fixes things...

alternative BD burning guide
by Andrew Randrianasulu 21 Nov '21

21 Nov '21

https://lists.fedoraproject.org/archives/list/[email protected]… oh, so many details about error management! from 2013.. ==== To summarize the process: Use x264 through ffmpeg or directly to convert the video to H.264 per the recommendations on www.x264bluray.com. Add the -fps flag if you need it. Unless you have a REALLY fast machine or an eternity to wait, use the slow preset instead of veryslow. Extract the audio, I used ffmpeg to extract the existing AC3 audio. Use tsMuxeR to create the proper blu-ray folder structure and mux'ed stream (unfortunately not FOSS, but free) Use ImgBurn under WINE to create the image for burning, which supports UDF 2.50 for blu-ray (and 2.60, but that's not needed). === so for now tsmuxer IS free, but imgburn not. imgburn might require setting windows version in Wine to winxp https://www.imgburn.com/ in theory new mkudffs can be used for making udf image, and then.. try udfclient (cli tool from netbsd) to put files into it (should be in debian/ubuntu) ? https://openports.pl/path/sysutils/udfclient === udfclient interactive commands ------------------------------ These are ftp-like, with some differences. Use the 'help' command at the "UDF>" prompt to display a summary. Of particular value is a 'get' or 'put' of a directory. This will copy the entire structure in or out of the filesystem. === https://github.com/pali/udftools/issues/20 https://superuser.com/questions/1552763/using-udfutils-to-create-a-data-bd-… note, some of those links contradict each other on (un) ability of udfcliet to put files/dirs into udf 2.5 formatted image... Only test will tell.. (afterwards usual linux kernel driver should show files in r/o mode) nerolinux is also non-free (and from 2012) https://medium.com/@justdan96/using-nerocmd-in-ubuntu-19-10-627c5b157fed http://home.thomas.pp.ua/soft/linux/Nero%20Linux%204.0.0.0%20x86_x64/ (not tested)
