I don't think i ever had problems compiling on Arch/Manjaro, but multiple times where an update killed the system. And yes, without fixing configure.ac you cannot build. There ought to be a Arch/Manjaro section in bld_prepare.sh. Not so difficult to do but very tedious (adding packages from clean install until you have just enough. I would do that in a VM and make a "clean" snapshot before starting). ==== pkglist ==== acpi acpid amd-ucode android-tools appimagelauncher audacious audacity audiofile autoconf automake avldrums.lv2 b43-fwcutter bison blop.lv2 blueman bluez-utils boost calf catfish clinfo cmake cpupower ecryptfs-utils eteroj.lv2 evolution exfat-utils firefox gcolor2 gmsynth.lv2 gnome-disk-utility gnome-icon-theme gparted grub-theme-manjaro gtkhash-thunar gufw gxplugins.lv2 hexchat htop inetutils inxi iputils ipw2100-fw ipw2200-fw ir.lv2 jbigkit kernel-alive lib32-flex lib32-mesa-demos libreoffice-still libva-utils licenses light-locker lightdm-gtk-greeter-settings linux510 linux54 make man-db man-pages manjaro-alsa manjaro-browser-settings manjaro-documentation-en manjaro-firmware manjaro-hotfixes manjaro-pipewire manjaro-printer manjaro-release manjaro-system manjaro-wallpapers-18.0 manjaro-xfce-settings mda.lv2 meld memtest86+ menulibre mephisto.lv2 midi_matrix.lv2 mkinitcpio-openswap moony.lv2 mousepad mtpfs mugshot nano nasm network-manager-applet networkmanager-openconnect networkmanager-openvpn networkmanager-pptp networkmanager-vpnc nfs-utils ntp numlockx octopi pamac-gtk patch patchelf patchutils pidgin pkgconf pocl powertop pwgen qpdfview screenfetch sherlock.lv2 spectre-meltdown-checker steam-manjaro systemd-fsck-silent tellico terminus-font the_silver_searcher thunderbird timeshift tlp ttf-inconsolata ttf-indic-otf udiskie vdpauinfo vi viewnior virt-manager vm.lv2 wallpapers-2018 wallpapers-juhraya xcursor-simpleandsoft xcursor-vanilla-dmz-aa xdg-user-dirs xf86-input-elographics xf86-input-evdev xf86-input-void xf86-video-amdgpu xf86-video-ati xf86-video-intel xf86-video-nouveau xfburn xfce4-appfinder xfce4-battery-plugin xfce4-clipman-plugin xfce4-cpufreq-plugin xfce4-cpugraph-plugin xfce4-dict xfce4-diskperf-plugin xfce4-fsguard-plugin xfce4-genmon-plugin xfce4-mailwatch-plugin xfce4-mount-plugin xfce4-mpc-plugin xfce4-netload-plugin xfce4-notes-plugin xfce4-power-manager xfce4-pulseaudio-plugin xfce4-screenshooter xfce4-sensors-plugin xfce4-session xfce4-settings xfce4-smartbookmark-plugin xfce4-systemload-plugin xfce4-taskmanager xfce4-terminal xfce4-time-out-plugin xfce4-timer-plugin xfce4-verve-plugin xfce4-wavelan-plugin xfce4-weather-plugin xfce4-whiskermenu-plugin xfce4-xkb-plugin xfdesktop xfwm4 xiccd xmonk.lv2 xorg-server xorg-xkill yasm yelp zensu zsh ================= ==== aurlist ==== galculator-gtk2 libquicktime orage =================

Images sequence
by Andrea paz 25 Mar '22

25 Mar '22

I've tried to do a few renders with image sequences as output. The render is successful; the index file and all the image-frames are formed. Render::render_single: Session finished. ** rendered 939 frames in 7.719 secs, 121.648 fps I attach the index file. You can see that it is constructed well but it does not contain the link to the various tiff images. So it is not possible to load it in CinGG. I have this error message: /home/paz/list/test%05d.tiff: Not a TIFF or MDI file, bad magic number 19785 (0x4d49). virtual int FileTIFF::read_frame_header(char*): Error while opening "/home/paz/list/test%05d.tiff" for reading. I tried with various tiff settings and other profiles (png and DPX) with the same result. If instead of ffmpeg I use the internal engine I get the expected result: the file list is complete with links to the various image-frames and the loading in CinGG is successful. Tried with tiff, png and openexr. Does it work for you to render image sequences with ffmpeg?

Cinelerra context help - a complete implementation
by Georgy Salnikov 24 Mar '22

24 Mar '22

Hi all, This new implementation of Cinelerra context help can be requested from almost any Cinelerra window or subwindow by pointing with the mouse cursor on the GUI element of interest and pressing Alt/h. That HTML manual page will be shown via the configured web browser, which is assumed as most relevant to the GUI element being currently under the mouse pointer. For more information see issue 568 on the bugtracker: https://www.cinelerra-gg.org/bugtracker/view.php?id=568 How to install, configure and demonstrate the new functionality --------------------------------------------------------------- 1. Apply the patch (see BT568) to the CinGG source tree: https://www.cinelerra-gg.org/bugtracker/file_download.php?file_id=775&type=… 2. After patching one new file appears: doc/ContextManual.pl. This is a perl script. It must be given exetutable permissions. 3. Build and install CinGG as usual. 4. The prerequisite for context help is CinelerraGG HTML manual. After installation of CinGG itself, place the complete unchanged directory CinelerraGG_Manual, as it was produced by latex2html from the manual package, into the 'doc' directory of the installed Cinelerra package. This will be the directory bin/doc/CinelerraGG_Manual if CinGG was built --with-single-user. The script ContextManual.pl should appear after installation also here, in bin/doc. 5. In principle, this is sufficient. Nevertheless, the bin/doc/ContextManual.pl script can be configured further. Look in the script text. You can define your preferable web browser, or redefine it to 'echo' for debug purposes. There are also some predefined HTML pages for Contents and Index, and several explicitly rewritten keyphrases. However, there can be hardly a need to redefine anything except the name of the browser executable. 6. Start Cinelerra and open a project with some assets, effects, keyframes, etc. May be, open some additional Cinelerra dialog windows, plugin settings, etc. Try to point with the mouse on different GUI elements or on empty spaces in different windows and press Alt/h. You should get different manual pages in the browser (if browser was not yet started, it should start automatically). How it works, from the user's point of view ------------------------------------------- The hotkey to request context help is Alt/h. Why? A simple 'h' does not fit: in text fields it has to input the letter 'h'. So is Shift/h: it would mean the capital letter 'H'. Ctrl/h and Ctrl/Shift/h are also not suitable: it is <Backspace>. Something like <F1> would be also not good, <Fn> are already utilized in Compositor. Unlike these all, Alt/h seems to be a good hotkey and, to the best of my knowledge, it is not assigned to anything else throughout the whole Cinelerra code. What particular help page is shown, depends on the mouse cursor location while Alt/h is pressed. Usually, when the mouse is located in some window or dialog, the help page related to the functionality of this window or dialog is shown. In this case the mouse can point either on some widget, or on an empty area in the window. In Cinelerra GUI there are several rich loaded windows, Timeline and Compositor for example. In such a case different help pages can be requested depending on the particular GUI element under the mouse. For example, pressing Alt/h while pointing on the Autos curve in a track would show help on automation keyframes, pointing on the Overlay mode button in the patchbay would show help on overlays, pointing on the camera control in Compositor would show help on camera and projector. If no context dependent help page is found, the manual page of Contents itself is shown. Most probably it means, that either the meaning of this window is obvious (so is the 'Tip of the day' window, for example), or it is not (yet) documented. Requesting context help for plugins ----------------------------------- There are following possibilities to request help page for the particular plugin of interest. 1) Pressing Alt/h with mouse in the dialog window of plugin settings 2) Pressing Alt/h while pointing with the mouse on the plugin bar in a track (or transition bar, or transition icon) 3) Pressing Alt/h while pointing on the plugin name (icon) in the Resources window. If plugin tooltips are on, help for the highlighted (plugin under mouse) is shown. If plugin tooltips are off, help for the selected plugin is shown (it is made so, because in the latter case it would be difficult to figure out, without a visual feedback, which particular item is currently under mouse). 4) Pressing Alt/h while pointing on the plugin name in the Attach Effect dialog Requesting context help on Contour Shuttle ------------------------------------------ Contour Shuttle has no Alt/h, yeh. Nevertheless, its help page can be requested by simultaneous pressing both Alt keys (left and right) on the keyboard followed by pressing any button on the Contour Shuttle. Here, pressing both Alt keys is necessary due to the way of X11 to track the status of modifiers. To cancel this mode, press any single modifier key (Alt, Ctrl or Shift) once. _______________________________________________________________________________ Georgy Salnikov NMR Group Novosibirsk Institute of Organic Chemistry Lavrentjeva, 9, 630090 Novosibirsk, Russia Phone +7-383-3307864 Email sge(a)nmr.nioch.nsc.ru _______________________________________________________________________________

emulation of middle mouse button via xinput
by Andrew Randrianasulu 22 Mar '22

22 Mar '22

Because I also run cin on laptop (for now) I found this info useful https://dev.to/bramaudi/enabling-mouse-middle-click-emulation-in-linux-23nb also, if you accidently try to capture too big area (for example 1600x1200 vs real 1600x900) you will get black capture window and some X errors on console...

question about dvd.dvd profile
by Andrew Randrianasulu 20 Mar '22

20 Mar '22

May be we can add cin_bitrate=8000000 to it, so default will work better? (otherwise re-encoding for example dothack2.mpeg from samples.mplayerhq.hu without setting bitrate resulted in blocky encode)

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 18 Mar '22

18 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?
