ffmpeg scene detection scripts
by Andrew Randrianasulu 19 Mar '22

19 Mar '22

I was looking for some equivalent of automatic scene detection, and found those scripts https://github.com/NapoleonWils0n/ffmpeg-scripts#scene-cut they work by re-encoding from original clip, but may be they can be modified for using 'copy' codec over i-only videos? $ ./scene-detect -i ~/dothack2.mpeg -t 0.2 -o cutfile.cvs (detects two scene changes) ./scene-time -i cutfile.cvs -o cutfile $ ./scene-cut -i ~/dothack2.mpeg -c cutfile $ cat cutfile.cvs 00:00:00 00:00:12.36 00:00:16.896 $ cat cutfile 00:00:00,00:00:12.36 00:00:12.36,00:00:04.536 $ lowering threshold to 0.1 'detects' one more scene change, so video split into 3 parts.

vp9 high bit depth, vp9 lossless profile
by Andrew Randrianasulu 17 Mar '22

17 Mar '22

so I played around with vp9 enciding a bit more. apoarently there is vp9 lossless mode, and additionally libvpx can support high bit depth if configured so. I also tried to remove (currently unused?) libavdevice build from ffmpeg, and fix termux breakage (libandroid-shmem lib was missing) try attached patches and check if vdpau/vaapi still works?

Cinelerra-GG_Manual. A stupid thing. FFMEG instead of FFMPEG
by Igor BEGHETTO 08 Mar '22

08 Mar '22

In the Manual_20220228.pdf there are stupid errors at the pages 167 and 168 because I wrote wrong in the CinelerraGG Forum https://www.cinelerra-gg.org/forum/help-video/how-to-optimize-playback/?ord… It should be "Rescaled to project size (*FFMPEG* only) = unchecked" instead of "Rescaled to project size (*FFMEG* only) = unchecked". Sorry for my mistake. IgorBeg

Re: [Cin] Creating AppImage
by mat 28 Feb '22

28 Feb '22

After upgrading the latex2html on Fedora_35, both PDF and HTML manual build fine. But, using diffpdf to compare the versions produced in Mint 19.3, Mint 20.3, and Fedora 35, the Mint version differ in only 27 words, but Fedora much more. In the Mint versions, diffpdf (when comparing words) highlights e.g. on chapter 1.3.4, table 1.1, page 15, for much of the table the "yes" and "auto" words, even though I cannot see a difference between them. The source .tex file are all the same. Also, on that table, on Mint 19.3 the entry for x264 is on the next page, on Mint 20.3 it is at the same page, last entry in the table there. So the layout is not exactly the same, even though differences are very small (sometime a line is on a different page). The two version have the same number of pages, though. On Fedora 35, there are 576 word different compared to Mint 20.3, the Fedora manual is also 2 pages shorter. E.g. on page 63, "Preset shapes section" on Mint 20.3 the last line ends with "The first" , on Fedora there is an extra line after that. I am not sure it is worthwhile investigation this difference, nothing obvious jumps to the fore when comparing the log files. There are some warnings in Fedora's log that are not there in Mint, e.g. File: mdsffont.def 2013/08/29 v2.31 (Math Design Project) LaTeX Warning: Font shape declaration has incorrect series value `mc'. It should not contain an `m'! Please correct it. Found on input line 53. and multiple more of these for this font. I am not the same opinion of Georgy regarding that is does not matter where the manual comes from when joining it with CinGG. For the functionality it does not matter, but I believe that one should be able to build all parts of the whole shipped product (AppImage with online help), and that incldues the manual. MatN

Resource leaking and high memory usage
by Stefan de Konink 23 Feb '22

23 Feb '22

I have imported a bunch of 4K video's and created a proxy out of it. In that Cinelerra session my memory usage became 9.9GB. When closing the project and reopening it the totally used memory reduced. What to make of this? skinkie 30046 319 62.0 17949716 9986224 pts/1 Sl+ 10:34 124:49 cin skinkie 144059 51.9 47.0 16050360 7573660 pts/1 Sl+ 11:14 1:56 cin Regardless of the above, I wonder if the memory pressure can be reduced in any way. Are the IDX's taking up memory? -- Stefan

Blu-ray Tools and more testing
by Terje J. Hanssen 21 Feb '22

21 Feb '22

The following articles made me aware of some basic Blu-ray tools of interest: https://www.videolan.org/developers/libbluray.html https://wiki.gentoo.org/wiki/Blu-ray https://packages.gentoo.org/packages/media-video/bluray_info ======= After installation on current openSUSE Leap 15.3, this looks like: zypper se -is bluray Loading repository data...

GIT update of libvpx
by Phyllis Smith 18 Feb '22

18 Feb '22

Updated and checked into GIT, libvpx from 1.8.2 to 1.11.0. Compiled and 1 test on Fedora 32, Debian 9.1-32bit, and Ubuntu 16.04 and the reason was because the notes said Nasm 2.15 recommended. But Debian and Ubuntu both were at 2.13 and compiled OK and I rendered to VP9. Andrea, if you use VP9 a lot, could you do a couple of test on your Arch system? Andrew, I did update the patch1 also so I think I did it correctly but if not, just let me know. ...Phyllis

FFmpeg and X11-XV
by Andrea paz 17 Feb '22

17 Feb '22

FFmpeg drops XvMC hardware acceleration: https://github.com/FFmpeg/FFmpeg/commit/be95df12bb06b183c8d2aea3b0831fdf054… I wonder if it has something to do with CinGG's X11-XV driver.
