ffmpeg question
by Zbigniew Koziol 19 Nov '14

19 Nov '14

Hello, For some here the answer will probably be know right away. That is why I am writing, after long googling. I would like to create a sort of video presentation from images. However, I would like that every slide (image) is displayed for a different time duration. This is just the first step; next i would like to combine voice with that, but it is probably another problem, for later. Hence, I have a sequence of images y-%2d.png The following works for me: ffmpeg -framerate 1/10 -i y-%2d.png -c:v mpeg4 -vf "fps=2,format=yuv420p" out.mp4 And the following works, too: ffmpeg -r 1/2 -start_number 7 -i y-%2d.png -c:v mpeg4 -vf "fps=2,format=yuv420p" out.mp4 However, how to control the time of displaying individual images? Is that possible at all? I thought that something like this may work: ffmpeg -r 1/5 -i y-01.png -r 1 -i y-02.png -c:v mpeg4 -vf "fps=2,format=yuv420p" out.mp4 It does not. The first image is displayed, only. Kind regards from Poland, zb. -- Zbigniew Kozioł http://nanophysics.pl mobile: 500 685 477 stationary at home: 17 229 8940

paid help to install Ubuntu 14.04 server on old workstation?
by Joe Murray 18 Nov '14

18 Nov '14

I have an old workstation with an Asus P5Q motherboard, Core 2 Duo 2.4GHz and 6 500Gb drives. I've only done a few Ubuntu installs, and I'm having trouble getting past a problem with installing on a RAID device - my guess is that it was a problem with master boot record or something. Not sure if I have done something quite bad, but for some reason it no longer even shows BIOS stuff (yes, I've checked the cabling), and the power source doesn't sound quite normal for a few seconds after power on. Please contact me (offlist if that is netiquette here) with suggestions of who could help me with this fairly simple hardware/sysadmin task, either yourself or an organisation or person. Thanks, Joe Murray, PhD President, JMA Consulting joe.murray(a)jmaconsulting.biz skype JosephPMurray twitter JoeMurray 416.466.1281

What's a good scrum tracking tool?
by David Collier-Brown 18 Nov '14

18 Nov '14

I'm using jira, and now see why we previously dropped it in favour of yellow stickies and whiteboards (;-)) What's a good product, preferably one that is programmable, has a command-line or an api? I'm suffering from click-and-have-coffee syndrome, and the only thing programmable are csv uploads and pseudo-sql queries, via the gui. I want to manage stories and bugs filed against them. --dave -- David Collier-Brown, | Always do right.

Playing *.pls files in firefox?
by Walter Dnes 17 Nov '14

17 Nov '14

Showing my age here, I like oldies music. An interesting site is http://www.fun45s.com/ but firefox won't play it for me. Fortunately they give the direct stream URL on their homepage. If I try http://s7.voscast.com:8376 or http://www.fun45s.com/listen.pls in firefox, firefox asks for a .pls handler, and I point it to mpg123. It doesn't work. No music. But if I run mpg123 direcly from the commandline like so... mpg123 http://s7.voscast.com:8376 ...it works. Can I set up firefox to handle pls files direcly, or is there a player that firefox can invoke? -- Walter Dnes <waltdnes(a)waltdnes.org>

Firefox is a pig
by D. Hugh Redelmeier 17 Nov '14

17 Nov '14

My desktop has been up for a week. I have a lot of firefox windows and many more tabs open. FF was getting sluggish. It has taken 4k minutes of CPU. Not seconds. So that is about 10 hours of CPU per day. Even quiting is taking a long time. About 10 minutes so far. At 99% of the CPU. Yuck. Maybe I'll kill it. It is taking 8G of virtual memory and 4.5 G resident (according to top).

Virtual Machines Under Android?
by Scott Sullivan 17 Nov '14

17 Nov '14

First some background, then a question. Recently, due to my laptop becoming non-usable for mobile work, I've been taking much more advantage of my Android phone. Paired with a usb Lenovo compact thinkpad keyboard w/ track-point, and it's surprisingly very usable, the track point giving me a mouse courser and keyboard on a single USB-OTG connection. What I have found is that while you can almost use it as a desktop, it's clearly not, and you won't get the same efficiency of use. But it's led me thinking that this device is in many respects more powerful then my sub-notebook laptop (less the RAM). So the question. What have people done to run virtual machines on their Android phones? A few years ago I had tried out Limbo PC, which was a QEMU port to run x86 machines on your phone. You loose a lot of performance in the instruction set translation. I know the major Distro's have very robust ARM package sets at this point, so I'd look at running a native Linux in visualization. http://linuxonandroid.org/ This comes up in searches, but on the surface looks like their using a chroot method. Hmm... which I hadn't considered. -- Scott Sullivan

I stumbled on a DD-WRT drama
by D. Hugh Redelmeier 16 Nov '14

Kong quits development: <http://www.dd-wrt.com/phpBB2/viewtopic.php?t=269247&postdays=0&postorder=as…> subject: Ceasing Development As best I can make out, he did some/most/all of the ARM side of things (eg. for the recent Netgear wireless router). Much wailing and gnashing of teeth ensued, as well it might. Then it turned into a pile-on-colinsnj. Apparently he seems to want the GPL to be respected, and that others think that that is what drove Kong away. I kind of feel that colinsnj is right, but then that's why I'm not a dd-wrt user. Then Kong posts that it was all a joke and that he smoked out the evil Colinsnj <http://www.dd-wrt.com/phpBB2/viewtopic.php?t=269359> subject: !!! ~~~ YOU HAVE BEEN PRANKED ~~~ !!! One amusing part of the last bit: Kong wants others to do more of the work building "optware packages". To enable that: I instructed basmaf to prepare an openwrt build environment in order to build packages that are fully compatible with dd-wrt. The same is needed for arm and musl now. It is a bit more difficult in this case as a lot of packages need some work in order to compile with musl, so you should have some coding experience:-) This certainly reinforces the belief that DD-WRT folks don't want any but insiders to be able to build dd-ware. Some of the users seem to be suffering Stockholm Syndrome. They don't realize that they would not be so beholden to Brainslayer and Kong if this was really open source. Of course they would not have a good Broadcom driver either.
