"workaround_bugs=1" for ffmpeg decode
by Andrew Randrianasulu 11 Jul '21

11 Jul '21

I run into some cool but unwanted image distortion while playing back and forth sample file ~/matrixbench_highdivx_ac3.avi from samples.mplayerhq.hu sadly, setting this avctx flag doesn't fix artefacts, but I send it out anyway because someone might run into buggy early encode requiring this workaround variable to be set... I think you also can set it via opts file, but not tested this (because for me workaround does not improve image quality after few fast forward/fast backwards)

"interpolate bayer" documentation?
by Andrew Randrianasulu 09 Jul '21

09 Jul '21

I try to play this new .braw firmat using slightly modified ffmpeg patch from https://patchwork.ffmpeg.org/project/ffmpeg/patch/ 20191214115705.25497-1-onemda(a)gmail.com/#49278 test file #2 from (~500 mb, full hd, 13 sec) https://filmplusgear.com/blackmagic-raw-braw-testfile-for-download/ I can't see it automatically de-bayering data, so I used "interpolate Bayer" plugin. It works slooowly in software... {1.3 fps} And parameters not obvious. I think those coeffecients explained in https://github.com/rasmus25/debayer-rpi/blob/master/debayer.cpp // BGGR = 0,0 // GRBG = 0,1 // GBRG = 1,0 // RGGB = 1,1 because my bayer_rggb16le file now looks more correct with Interpolate Bayer controls set to 1/1 but can anyone test various raw bayer videos to see if it holds true?

It doesn't crash anymore but no way to listen to sound.. may be with vlc on Android side? xsdl has integrated pulseaudio client so there was different line to use... https://android.stackexchange.com/questions/205576/how-to-play-sound-from-t…

Output video's do not have same color, brightness/contrast as sources
by gorge rankin 07 Jul '21

07 Jul '21

Hello all, I'm truly loving cin/gg as I've switched to it as my primary editor. I do have one slight problem, which I can work around. But I'm wondering if I'm doing something wrong. My output video's don't look *exactly* like my sources. Even if I just drop in a video to CinGG and render it, the output is NOT the same as the input. I have to do these filters to get my output video kind of 'close' to that of my sources: Brightness/contrast filter: +.063 bright +1.292 contrast deselect boost luminance My input video's are recordings from OBS. I suppose I can just add more brightness & contrast inside of OBS and then they should come out of CinGG fine. I'd like to avoid adding filters to the render chain of cinGG to save me encoding time if I can. I have also completely removed my ~/.bcast folder and recreated my setup so as to avoid any conflicts there. Here is a 'mediainfo' output for a file that my OBS produces: General Format : Matroska Format version : Version 4 File size : 5.81 MiB Duration : 1 s 934 ms Overall bit rate : 25.2 Mb/s Writing application : Lavf58.45.100 Writing library : Lavf58.45.100 ErrorDetectionType : Per level 1 Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : High(a)L5.1 Format settings : CABAC / 4 Ref Frames Format settings, CABAC : Yes Format settings, Reference frames : 4 frames Codec ID : V_MPEG4/ISO/AVC Duration : 1 s 934 ms Bit rate mode : Constant Bit rate : 25.0 Mb/s Width : 2 560 pixels Height : 1 440 pixels Display aspect ratio : 16:9 Frame rate mode : Constant Frame rate : 60.000 FPS Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Bits/(Pixel*Frame) : 0.113 Stream size : 5.76 MiB (99%) Default : Yes Forced : No Color range : Limited Color primaries : BT.709 Transfer characteristics : BT.709 Matrix coefficients : BT.709 I'm using the latest CinGG app image on Ubuntu 21.04. It works great BTW! I am using RGBA-8 Bit for my cin-gg format. I'm rendering from cingg to h264 as well. I have the nvidia binary driver installed, version: 465.31 I also have the CudaSDK installed here as well. The 'overlay' mode is 'normal' in CinGG for the video track The 'fade' is at 100 in CinGG. Thank you for all your hard work on CinGG ! I truly appreciate it!

gmic's 'transition3d', mlt
by Andrew Randrianasulu 03 Jul '21

03 Jul '21

I was trying to rebuild gmic on termux with x11 support, but it requires too much memory..... but may be using gmic on set of images (exported by Cin and then re-imported) can be used as workaround for lack of native transitions of such nature? https://gmic.eu/reference/transition3d.html#top (i think you can try w/o blur first) I also built mlt 7.0.1 (multimedia framework) but w/o python support (so no flowblade). If you know any cool mlt command line I can try to run it here (on my small set of vids). Mlt7 apparently dropped few modules.. so kdenlive/flowblade must catch up with this. https://www.mltframework.org/docs/v7migration/

New AppImages available dated June 30, 2021
by Phyllis Smith 30 Jun '21

30 Jun '21

In the Download area under images, are the newest AppImages including, for the first time, a 32-bit version: CinGG-20210630-i386.AppImage -- 32-bit version built on Debian 9.1 (so not really that old of a distro) CinGG-20210630-x86_64-older_distros.AppImage -- built on ubuntu 16 CinGG-20210630-x86_64.AppImage -- built on Fedora 32 Updated PDF and HTML versions of manual. Added Tag to both source and manual GITs. Put html tgz manual in images subdirectory so it matches for self-builders to add fo Alt/h hotkey in bin/doc. Release notes updated. ************** Release Notes Summary *********** Additional choices for high FPS rendering Settings→Format have been added by Andrew for Video and Audio. This mod fixes the problem reported by Gorge where it was not possible to render at a format over 60fps. A speed improvement using av1.webm when rendering was implemented by Andrew. This makes it now possible to use this as it is 7 times faster on at least 1 typical multi-cpu laptop. Gang Channels and Gang Media was not correctly handling disarmed tracks as reported by Scossu in the forum and BT #577. IgorBeg tested a fix by commenting out the relevant code. Additional mxf container render formats added by Andrew to include 6 new video + 2 audio. Other new render formats include: h263.mov, h263p.mov, and improved cinepak.qt speed. An OBS Studio user, Sparkill, has contributed a render format for creating a youtube based on video recorded in OBS with Color Format: I444 (yuv444p), Color Space: 709, Color range: Full (JPEG) called “obs2youtube.mp4” in the render format Video and Audio wrenches. Upgrade of third party library: libjpeg-turbo from 2.0.5 to 2.1.0 via Andrew.

new overlay mode from Freelancer
by Andrew Randrianasulu 29 Jun '21

29 Jun '21

finally looked at history.. http://git.cinelerra-gg.org/git/?p=goodguy/history.git;a=blobdiff;f=cineler… and made this patch (attached) it works softer than logical or porter/duff modes, but notiecably slower ( (on 8 core arm tablet) my modes fails to compile - something about me not really knowing how to write macro functions (?)

possible cinepack profile speedup
by Andrew Randrianasulu 29 Jun '21

29 Jun '21

I basically added max_extra_cb_iterations=0 min_strips=3 this speedups encoder but quality is lower (not sure how much, was too inpatient to wait for 1 min clip encode at 352*144 25 fps! with those parameters ffmpeg encodes at nearly 3 fps, yay! In theory one can try to set up renderfarm + number parallel ffmpeg encoders, because encoder is single threaded - but I haven't tested this) also added two old (1996/8) h263 codecs - it theory they should be good for low-cpu decoding (on emulated computers for example), but apparently h263 without 'p' only good at few pre-defined resolutions? there is also speedhq.qt - for ffmpeg 4.4 (sadly ffmpeg can't encode video with alpha, as this mpeg2-like format supports...) sorry for not making progress on more important issues - I fiddled around with overlayframe.h - but I can't see my addons working? Either bug in code or I translated those blend modes wrongly.. there also two ffmpeg-4.4 patches recently added to git - they apply with patch -p1 yet not with git apply patch (misformatted patch).. Adds avc intra 300/480 if compiled against last x264 (15 june 2021)
