selectable vaapi decoder device
by Andrew Randrianasulu 22 Sep '23

22 Sep '23

Because I have this dual-gpu laptop with intel and radeon (r600) decoding devices I tried to get second (mesa/r600) device going but init failed .. I looked into decoding example: https://gist.github.com/kajott/d1b29c613be30893c855621edd1f212e and created attached patch now you can select your specific device with env variable: CIN_DRM_DEC=/dev/dri/renderD129 DRI_PRIME=1 LIBVA_DRIVER_NAME=r600 bin/cin in theory same treatment can be applied (with different variable name) to second instance of av_hwdevice_ctx_create (in hw encoder init) but I have no device to test it ...

cin freeze with group move?
by Andrew Randrianasulu 21 Sep '23

21 Sep '23

So, I tried some of the simples group move moves. 1) load 28 sec of media (1 audio/1 video mp4). 2) switch to d&d mode. 3) double-clic on video track where media piece is. It highlight it and add both A and V to group (observe little lines highlighting them) try to drag group somewhere. It usually works one time but not second. dump reads: BC_Signals::dump_stack cin() [0x88b2082] linux-gate.so.1(__kernel_rt_sigreturn+0) [0xf7ec8570] cin() [0x85e6032] cin(_ZN3EDL18delete_edit_labelsEP9ArrayListIP4EditEi+0x43) [0x85e82d3] cin(_ZN7MWindow10move_groupEP3EDLP5Trackdi+0xa9) [0x86b6eb9] cin(_ZN11TrackCanvas9drag_stopEPi+0x3bf) [0x87c708f] cin(_ZN10MWindowGUI9drag_stopEv+0x4f) [0x86c11df] cin(_ZN11TrackCanvas15drag_stop_eventEv+0x1a) [0x87b6f7a] cin(_ZN13BC_WindowBase18dispatch_drag_stopEv+0x683) [0x88d5793] cin(_ZN13BC_WindowBase23dispatch_button_releaseEv+0xb8) [0x88d5968] cin(_ZN13BC_WindowBase14dispatch_eventEv+0x73e) [0x88e0d0e] cin(_ZN13BC_WindowBase10run_windowEv+0x98) [0x88e15b8] cin(_ZN7MWindow3runEv+0x31) [0x86d7be1] cin(main+0x4cf) [0x83bfdef] /lib/libc.so.6(__libc_start_main+0xf9) [0xf5e4d909] cin(_start+0x21) [0x83c7fa1] full dump attached ....

CinGG/NLE comparison
by Andrea paz 20 Sep '23

20 Sep '23

I attach the pdf and odt file to put in the git repository. It is the union of my and Phyllis' writings. It is for new users to compare the workflow they are used to with the one in CinGG. I created the document in odt because it is a work-in-progress that everyone can contribute to. I am not familiar with Adobe Premiere Pro or other NLEs, so I may have written inaccuracies and errors. If you can revise and improve the document, please do me a favor.

Pancake editing
by Andrea paz 12 Sep '23

12 Sep '23

Also from the YouTube channel "Film Editing Pro" is an overview of 3 editing methods: 1- three points editing (Two Screen Editing, in CinGG) 2- Timeline editing (Cut and Paste + Drag and Drp, in CinGG) 3- Pancake (stacked) editing See: https://www.youtube.com/watch?v=Tsohm9SE9Mk Panckake editing start at 3:31 Only Premiere Pro has pancake editing functionality [Note: actually Lighworks and even DaVinci Resolve have this functionality]. PP indeed allows you to open multiple timelines, place them on top of each other in a stack, and operate between clips of these with Drag and Drop. One feature of pancake editing is the ability to see a timeline on the Source Monitor (our Viewer window); thus one timeline is seen on one monitor and the other on the other monitor (The classic Program Monitor -Compositor window, in CinGG). In fact, it would be difficult to do editing without seeing the contents of the clips on the monitor. In CinGG, in my opinion, we can do a workaround that simulates pancake editing even though it is not quite the same. Just open multiple instances of CinGG, bring the program windows of all instances closer together, and operate between timelines not with Drag and Drop but with Cut and Paste. We can't display a timeline in the Viewer window, but we don't need to since each instance's timeline carries its own Compositor window where to see the contents of the edits. I am convinced that opening multiple instances of CinGG is no more heavy than opening multiple timelines in PP. What are your thoughts on this?

Timeline x Hollywood
by Andrea paz 12 Sep '23

12 Sep '23

To make up for my recent mistake (timeline = canvas), I offer a curious video on what a timeline looks like for large professional projects. However, their entire YouTube channel is interesting and informative. https://www.youtube.com/watch?v=oWXqYd-OhaA

Still on hardware acceleration
by Andrea paz 05 Sep '23

05 Sep '23

@Andrew Sorry to bother you again on a subject you have already tried to explain over and over again. Reading this page: https://trac.ffmpeg.org/wiki/HWAccelIntro it is my understanding that when decoding (note: from here on I am only referring to decoding/playback!) you can use the "-hwaccel" option without any other settings. If the media file used supports hardware acceleration, then it will be used automatically without anything else to do. If it is not supported it will automatically switch to software decoding. There is no need to specify the device (because a device is automatically selected, even if it is not the preferred one), so it would be a generic feature that decides for itself when to run. Question, how can I impose "-hwaccel" when compiling CinGG? Another thing concerns decoding with Vulkan. Again, these are generic instructions and I would like to test it, however it requires device initialization, to be declared explicitly (although a generic term is fine: "vulkan=vk:0") and a few other options. See here: https://trac.ffmpeg.org/wiki/HWAccelIntro#Vulkan The question is always the same: How can I compile vulkan in CinGG to do some tests?

Monthly AppImage updates
by Phyllis Smith 05 Sep '23

05 Sep '23

April 30th AppImages are now available with the binary only updated with X264 r3106 stable mods. But, I have a problem with being able to update the GIT repository on the server due to some error I made which I am now working on. Release Notes Update below: *********************************** GIT for Cinelerra-GG has the following changes from 04/01/2023-04/30/2023 *Server Maintenance work has been done by Sam* on an ongoing basis along with the difficult task of accommodating newer requirements by Google Gmail. Changes to the Mailing List settings for compliance was very time-consuming and much appreciation goes to Sam for continuing to volunteer his time for critical needs. *X264 *has been upgraded to r3106 stable release. There appears to be no X265 stable updates. *Clang-16* related modifications in thirdparty/Makefile, libuuid-1.0.3, and mpeg2enc.c to support new termux distro have been contributed by *Andrew*. *Prores_ks *render format has had the Apple writing library added as the default with ffmpeg since that is who created this specific prores format. This should make the rendered video more compatible with other software products. Mod provided by *Andrea*.
