Kdenlive kde-apps/kdenlive Avidemux media-video/avidemux The first one is KDE based. Last time I used it, it was large but had lots of fancy stuff it could do. The second one has both a gtk and qt based version. I'm guessing that is controlled by USE flags. I seem to have both of them here. :/ Maybe one of those will help. Dale :-) :-)
[gentoo-user] Recommend a simple video editor?
I've got a handful of mp4 video clips (a minute or two each). All I want to do is 1) Concatenate them with fade-in at beginning of each clip and fade-out at the end of each clip. 2) Superimpose a title at the beginning for a few seconds. Can anybody recomment a simple video editor? So far I've tried Openshot and Cinelerra and niether is usable even for my trivial task. Openshot 2.07 The native amd64 build segfault a _lot_. Any time you try to move the "playback head" or whatever it's called it segfaults. Various other GUI operations also cause a segfault. Sometimes it gets the project file into some broken state and then can't even start up and load the project file without segfaulting. Oh, and it "auto saves" periodically, so you can't even rely on it not borking a working project file even though you never clicked "save". The AppImage binary at least allows the GUI to work, but it can't render a 5 minute video. It either aborts part-way through or just locks up burning 100% CPU until you send it a SIGKILL. I was finally able to set up the edits using the AppImage binary, then open the project using the native Gentoo binary and render the video. The resulting video quality was terrible. The video stuttered, pixellated, and in some spots even appeared to jump forward/backward repeatedly. That was with the highest quality setting (the output file size was acually significantly larger than the sum of the input file sizes). Even though the video quality was severly degraded. Cinelerra 2012 (stable). I used Cinelerra for a small project once before, and though it _worked_ I hated every second of it. The GUI is a nightmare. It uses some home-made widget set that I find incomprehensible. I could probably grit my teeth long enough for this simple task, except Cinelerra seems unable to deal with AAC audio. It misidentifies as some other PCM format, and all of the imported files just have a short burst of noise at the beginning followed by silence. Cinelerra also doesn't seem to be able to play the imported.mp4 video files at the proper framerate it's bog-standard Android phone video: H264 1280x720 30fps, but Cinelerra insists on playing at a some higher frame-rate. I may try Cinelerra 2014, but I'm not optimistic -- Cinelerra is known for it's slow rate of change.

Yes, KDE uses /etc/plasma/shutdown/10-agent-shutdown.sh and I guess gnome would have its equivalent, but I think this is only for any daemonised services running on the desktop. I suspect that: /usr/bin/kdeinit4_shutdown /usr/bin/kdeinit5_shutdown are used to shutdown gracefully any KDE apps. > You could try looking for something similar with the desktop/window manager > of your choice. I tried the above shutdown commands but they didn't work. Unfortunately enlightenment does not have anything available to stop desktop applications at shutdown. The dev's advice was to use .xinitrc or equivalent. > I think .xsession is run only during start and will not 'pause' during the > session. Well my confusion is that my .xsession *was* working fine until a couple of weeks ago ... and all still works as expected when I run akonadictl stop in a terminal before I shut down. I don't know why the same command behaves differently in .xsession now. :-/ PS. When I just log out there is no delay. The problem only arises when I shutdown. I wonder if this is something to do with this darn sddm display manager ... -- Regards, Mick signature.asc Description: This is a digitally signed message part.

Kde and I would assume Gnome as well have a method of running a script when starting and stopping a login session. This is usually used for ssh-agent and pgp-agent. You could try looking for something similar with the desktop/window manager of your choice. I think .xsession is run only during start and will not 'pause' during the session. -- Joost -- Sent from my Android device with K-9 Mail. Please excuse my brevity.

I've setup thousands of routers over a lifetime, from dozens of vendors. Never seen shitty_er documentation in my life.

Furthermore, they have deviated from the vyatta tree and refuse to even qualify how they have deviated. I'm not so sure any robust penetration testing has occured on their products. Here's one 'gaping hole':: "Ubiquiti Networks tried to do a good thing and bring Internet connection to Third World regions this year. Unfortunately, it's just been discovered that their routers are being actively exploited by hackers to field massive DDoS attacks, due to an overlooked exploit." Google, there are tons of problems with ubnt no thanks on ERL3. Besides, some gentoo devs, after months of work, discovered that some of the hardware is unacessible, once your install embedded linux and the processors is way under-powered, and thus susceptible to a wide variety of DDoS attacks. > It's surprising that there are so few routers to choose from, even when > you don't limit your selection to FOSS. > On a side note, never buy Cisco, not even used: They won't let you > download or otherwise obtain a replacement for the damaged firmware > image (not to mention an update) that came which the device, unless you > have a support contract with them.

Cisco does not write most of their code anymore. Silicon vendors write much of the code, in a thousand different methodologies based on the personal prefferences of the overworked engineer that wrote the code. It the good-old-days of cisco (when they have legions of excellent coders they re-wrote most all vendor code to internal cisco standards; but that mantra has vanished, and most of their older-excellent asm/C coders are long gone. Yep cisco is a well-spring of buggy/shitty codes written mostly by hardware EEs. Dont believe me? Find a disgruntled cisco coder and get them drunk at the Bar (and promise them a better job). Yes there is an opportunity here for gentoo-hardened images, including stage-4 for a default router setup and the user can just add a few packages. It's a dam shame, the state of router affairs.
