ffmpeg.git.patch9 (cuda hwaccel) started to fail again ...

Hello, all! Just to report small observation https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=blob;f=cinelerr… started to fail with yesterday's ffmepg (commit 3750e36aa8ecb53764e5549470a39cd14ff6b513) Probably due to https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/7f149b04520c01002a2c199f856… ("lavu/hwcontext_cuda: refactor context initialisation") I just disabled this patch for my local build for now (no CUDA/nvenc software here) Another interesting recent hit in ffmpeg - Vulkan filtering, and https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/31d7b17c4671329a372e2762b4c… ("avcodec/hevc: add support for Frame Duplication (Doubling/Tripling)") - on decoding side, as far as I understand ....

Stupid question about pixel conversions in CinGG (xfer functions)
by Andrew Randrianasulu 19 Feb '20

19 Feb '20

Hi, all! I was looking again at https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=blob;f=cinelerr… and I think it works (via generated functions from guicast/xfer) by doing pixel-at-a-time, with slices done at different CPUs. Is there possibility to optionally add few stagin buffesr, so something like http://gegl.org/babl/index.html#Usage will have chance to work? "The processing operation that babl performs is copying including conversions if needed between linear buffers containing the same count of pixels, with different pixel formats." So, address calculations usually send down to Cin's own (slow?) functions will be reused to calculate size of buffer (per slice, as done by slicer function), and then babl or ffmpeg or something will transfer pixels to this new buffer, and then .. I dunno, signal 'done' to upper calling function and switch pointers to this new buffer? So, tricking Cin into thinking conversion (per sliced area) was done by its of functions, yet using different set of them (not those row-based macro expanded functions I see in build tree)? As long as pixels organized the same (row x column), and internally represented by same datatypes (like, first 4 bytes is R in float, second is G, third is B, and last 4 bytes is alpha ... for total of 16 bytes per pixel) this should work? Or I missed something?

Crash, again!
by Andrea paz 15 Feb '20

15 Feb '20

I have numerous crashes using openEDL. I don't know if they are related to the crashes I had some time ago, but these are also reproducible in root and so I got a useful dump. I simply put an edit in the clips folder using the "to clip" button (format=.3gp). Then I open that folder; RMB on the clip and click OpenEDL --> crash!

Bhodi Linux
by Andrea paz 10 Feb '20

I might be wrong, but Bhodi Linux doesn't have CinGG pre-installed. If this is the case, we could remove it from the Download page of the website so that AVLinux stands out more.

PulseAudio

I do not understand if Pulse Audio works "out of ten box" or we have to build it with its flag.

CinelerraGG static and dynamic tar build for Gentoo version base 2.6
by Phyllis Smith 02 Feb '20

02 Feb '20

Finally were able to create a Gentoo system partition and build Cinelerra there. There are 2 tars available and because gg was able to incorporate Gentoo into Xen, he will be able to build these monthly (at least for awhile). They are at: https://cinelerra-gg.org/download/tars/cinelerra-5.1-gentoo-20200202.x86_64… https://cinelerra-gg.org/download/tars/cinelerra-5.1-gentoo-20200202.x86_64… Standard tar install procedure as in the README.txt file in the download directory.

New builds ready
by Phyllis Smith 02 Feb '20

02 Feb '20

New builds are ready and it includes the addition of OpenSuse Tumbleweed. We had network problems here the last 2 days so it took awhile to upload them. There is also a one-time BSD tar file in the "File Storage" area and Windows10 limited. What is in the release is documented in the releasenotes.pdf as usual and this month's is included below. The plan for Multiple Timelines this month did not work out as we could not come up with a solution. ----------------------------------------------------------------- *Cinelerra-GG (Version Infinity) Release Notes for 01/01/2020-01/31/2020 for builds* https://cinelerra-gg.org/download/CinelerraGG_Manual.pdf The newly converted to *LaTeX manual* is complete and you can view the PDF from the website under Download->Documentation→User Manual. From within Cinelerra, the shell cmds icon has a pulldown for network access to this manual. Existing users will have to change the reference in their .bcast5 directory Cinelerra_rc file from a lower case “m” to an upper case “M”. Although there have been numerous contributors, Andrey’s push recommending latex and setting up the Github and Andrea’s conversion of the contents from .odt to .tex made it all happen. 1. New feature of editing/using a *File by Reference* has been added. In the load menu, this would be the EDL strategy of Reference (uwe request in BT # 318). Warning on usage is in the manual. 2. *WinTV Hauppauge remote control* added for over the air TV from within Cinelerra. This requires a small kernel mod that was checked into GIT. Additionally the previous ATI x10tv and android remotes were modified to provide similar interface. 3. *Windows 10 with Cygwin* limited Cinelerra build is now available. See the manual for install and details on usage. 4. *Pulse Audio* was added as it was needed for the MS Windows port. You will have to build with it. 5. *BSD *patch re-created as it has been 1.5 year since it was updated (Yuri request) and a tar created. 6. *Usability Improvements:* Open EDL, a recently added feature, has been amplified. In addition to the Insertion Strategy in the Load Files menu, there is now an EDL Strategy for advanced usage to load as a Clip, Nested, or File Reference. Group highlighting improvements have been added for drag and drop editing to prevent dropping on disarmed tracks and to correctly notify user via color highlights when dropping or overwrite is acceptable. In addition, there is now stickiness when next to another edit making it easy to drop exactly next to that edit (IgorB BT # 362). Settings→Preferences, Appearance menu has been rearranged because the Flags area was running out of space. Snapshot and Grabshot default destination has changed from /tmp to $HOME/Pictures so that new users will not be surprised when a reboot deletes their work. Existing users will have to manually change the location in Settings→Preferences, Interface tab, Snapshot Path (Rafa suggestion). *More Spanish translation* adjustments have been made by audiovisual technician, Rafa, to include the newly added phrases of the last few weeks. This is on top of all of the Spanish translations recently made by Sergio. Refinement by Rafa is to accommodate the different interpretations of the audiovisual world, which is very particular in this regard with some appropriate nuances. 7. *Bugs/Issues fixed:* A build probe fix for a52 has been added, stdint.h (ferdnyc, BT # 359). Nested Proxy fix to save the nested files in $HOME/Videos instead of Cinelerra executable directory. This makes it possible that saving your project in proxy mode will work correctly and nested files will not get accidentally deleted when install a new Cinelarra (IgorB email). Reworked perpetual session load/save strategy to handle levels with Open EDL and undo’s better. Fixed 3 lock boobies and minor build cleanups. Loaded clips now have the filename and modification time in the comments. Left margin for meters in the Compositor and Show Levels is slightly larger (IgorB report). Load window filebox resized to be a little bigger so no words are occluded. Added a target directory option to the Transcode menu making it convenient for DVD transcoding. Fixed broken vicon. DenoiseFFT plugin had a SEGV in an edge case that has been fixed (David analyzed/reported). A fix for spurious hard edges has been added. Minor one last fix for xft font problem, hopefully the last. FFmpeg color space / color range fix but not verified yet (Dejay reported).
