GIT checkin includes Cakewalk update + limited specialized hardware acceleration options.
by Phyllis Smith 17 Jun '19

17 Jun '19

Today's GIT checkin includes: - Cakewalk update - Nvenc option for encoding/rendering hardware acceleration for computers with Nvidia graphics for h264/h265. - Cuda build option for systems that already have the Cuda software loaded - with 2 demo plugins available. ---------------------------------------------------------------------------------------------------------------------------------------------- More info on the hardware acceleration options follow. Some testing done on Fedora 29 and Leap 15, but not all possibilities have been tried. I would expect to see some fallout. ---------------------------------------------------------------------------------------------------------------------------------------------- NVENC/NVDEC for Nvidia graphics board encoding and decoding will automatically be built by way of the configure scripts. But first, before anyone gets too excited, let me just warn you that the ONLY encode codec Nvidia chose to support is H264 and H265 with H265 available on just the latest graphics boards (supposedly at least the ones with the Maxwell chip). Also included in the ffmpeg build is "nvdec" but we have not figured out yet how this affects the hardware acceleration already in place with the use of CIN_HW_DEV=vdpau. Some information that was posted online 11/04/2018 -- "VDPAU falling away into irrelevance but no clear statements that consumers should switch to nvdec or that nvidia will advance VDPAU feature parity. ...All of these things make it hard to see what the correct way to approach nvidia support is, and even if you pick one, you can't actually integrate in a simple way." The easiest way to determine if nvenc is working for you is just to do a short render using h264_nvenc.mp4 or h265_nvenc.mp4 and see if it works or just gives you an error message. Error message for computers without nvdia cards (or not implemented) is: Cannot load libcuda.so.1 on the window from where your started cin. BTW this libcuda is part of nvidia libraries in the Operating System and does not mean you have CUDA in. A 2 minute demo from Big Buck Bunny 3804x2160, took 6 minutes 3 seconds with nvenc to render as opposed to 22 minutes 30 seconds without nvenc -- so not quite 4 times faster and I had no plugins added on a 4 core Intel laptop with an Nvidia 950M graphics board. ------------------------------------------------------------------------------------------------------------------------------------------- CUDA® is a parallel computing platform / programming model that provides big increases in computing performance through use of the GPU, graphics processing unit. It was first introduced in about 2006 for applications in computationally intense fields such as astronomy, biology, chemistry, and physics. The use of Cuda is not going to improve the playing and rendering of video in Cinelerra EXCEPT in the case where you use a specific CUDA-enabled plugin that is computationally intense - sadly, most of what Cin does, Cuda will not help. Cuda is mostly a "block oriented algorithm" which works well for such things as "a flock of birds all flying next to each other". If you have already installed the Cuda software on your computer -- and let me warn you, this is about 3GB of additional space usage -- the default build in the configure script is for cuda is "auto". Otherwise it will NOT be included. Obviously, you must have the Nvdia drivers for your graphics board installed too. Cuda is available to install on your computer only for a specific set of Operating System distros. Go to the following website: https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86… and gg says follow the very good set of directions to install around 3 GB. It installs repos by package. Also, install the "fusion repo" -- we do not know if this needs to be installed or not, but all of our test included it. I will attempt to create a demo a little later and there will most likely be a Ubuntu16 and Mint18 build available soon for testing purposes. gg/Phyllis

Hi, IgorB. I found your shared track mask demo very instructive (as usual) and would like your permission to upload it to the HowTo forum.

\LaTeX manual

Hi, @ einhander I'm progressing slowly with chapter 9 (plugins.odt) [Cursed is he who stretched it out ;-)]. I have the problem of the big tables of Libreoffice Writer to import in latex (in Sketcher and Titler sections). How should this be done? I have not found any information about this. @Phyllis >From the BlueBanana section, I took out an sentence, it is unnecessary in a manual. In the Motion section I would like to add a Tip. What is your opinion? Blue Banana: (-) The preceding sentence implies that this is a limitation in that you can not just apply a Blur to the matte. Motion: (+) Tip: The motion vector is a text file located in /tmp. We can open it with a plain editor and modify the wrong $X\,Y$ coordinates, i.e. those that deviate from the linear interpolation, to correct the errors that always happen when we perform a motion tracking (jumps). It can be a long and tedious job, but it leads to good results.

[OT] Git problem, help!
by Andrea paz 11 Jun '19

11 Jun '19

In GitHub I can no longer do a "push", that is to say uploding my local repositories on Git. It gives me the following error: [paz@archpaz cin-manual-latex]$ LC_ALL=C git push Username for 'https://github.com': Andrea-Paz Password for 'https://[email protected]': Enumerating objects: 91, done. Counting objects: 100% (91/91), done. Delta compression using up to 8 threads Compressing objects: 100% (82/82), done. error: RPC failed; curl 56 OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 104 fatal: the remote end hung up unexpectedly Writing objects: 100% (84/84), 13.18 MiB | 101.00 KiB/s, done. Total 84 (delta 6), reused 80 (delta 2) fatal: the remote end hung up unexpectedly Everything up-to-date The upload always stops at 52% and always with the same error. It's a common thing, but the many ways to solve it don't work for me. See for example: https://stackoverflow.com/questions/6842687/the-remote-end-hung-up-unexpect… Can someone tell me how to fix this?

Improved Gradient Plugin
by Phyllis Smith 09 Jun '19

09 Jun '19

Today's checkin was to get the Gradient Plugin (as often used in masking) to create the same results when using the X11 driver and the X11-OpenGL video driver. A test version for Ubuntu16 is at: https://www.cinelerra-gg.org/download/testing/cinelerra-5.1-ub16-x86_64-sta… which contains all of the bug fixes added since May 31. gg/Phyllis

05 Jun '19

In the last release I have the following errors (on terminal) at startup: BC_Signals::x_error_handler: error_code=8 opcode=154,31 id=0x111 BadMatch (invalid parameter attributes) BC_Signals::x_error_handler: error_code=172 opcode=154,26 id=0x3400002 GLXBadDrawable BC_Signals::x_error_handler: error_code=182 opcode=154,32 id=0x3400002 GLXBadWindow In any case, CinGG starts up without any problems.

Transparency (alpha) problem seems to be fixed in latest GIT checkin +
by Phyllis Smith 04 Jun '19

04 Jun '19

Besides the fix for the transparency bug, a bunch of accumulated small bugs got checked in also. The lines preceded by ** were reported by users. The transparency bug was BugTracker #226. Below is a summary. A gl_probe for OpenGL usage was added to detect GL version 4.3 for the shader so automatically uses software instead for computers still at version 1.x. ** Transparency using OpenGL generally and specifically for the Title plugin has been corrected. TV recording batch path directory was not being set, only the filename, this is now fixed. Correction to handling YUV in openGL masking is in. Sync up mask engine with playback 3d bezier. Cleanup done in the Overlay plugin. Fixed “drag” checkbox coordinates in plugins like Title, CriKey,… rework/cleanup for render effect. ** The checkboxes for the mask numbers when there are no armed tracks caused SEGV, but now fixed. The Title plugin now updates gui if overlay coordinates change. If there are no active masks, do not do any checks and do not draw anything to avoid time spent. Always insert media at position 0 when using insertion strategy of “Append in new tracks“. Changed insertion strategy wording from “Paste at insertion point” to Paste over selection / at insertion point”. Corrections for crop vattachment vfrm copy and gl flip_y coords twice (in compositor). ** Fix for use of Render Effect SEGV as discovered by Ugin. It no longer crashes but without a track when using the Title plugin, it may be of little use.

ShellCmd for personal use
by Andrea paz 04 Jun '19

04 Jun '19

I read the Спицын Андрей's script and the Phyllis' answer: https://lists.cinelerra-gg.org/pipermail/cin/2019-May/000754.html I was wondering if it was possible to include in ShellCmd some ffmpeg filters that do not work in CinnGG. The commands are as follows: EXTRACTPLANES ffmpeg -i video.avi -filter_complex 'extractplanes=y+u+v[y][u][v]' -map '[y]' y.avi -map '[u]' u.avi -map '[v]' v.avi ffmpeg -i video.avi -filter_complex 'extractplanes=r+g+b[r][g][b]' -map '[r]' r.avi -map '[g]' b.avi -map '[b]' b.avi ffmpeg -i [r][g][b]mergeplanes=0x001020:yuv444p output.avi ALPHAEXTRACT ffmpeg -i video_with_alpha.avi alphaextract video.avi alpha.avi ffmpeg -i video.avi alpha.avi alphamerge video_with_alpha.avi LENSFUN ffmpeg -i input.mov -vf lensfun=make=Canon:model="Canon EOS 100D":lens_model="Canon EF-S 18-55mm f/3.5-5.6 IS STM":focal_length=18:aperture=8 -c:v h264 -b:v 8000k output.mov I can't even write a single line in Bash. Does anyone know if this is possible?
