Err....."snap"! https://forum.puppylinux.com/viewtopic.php?t=9700 This of course 'creates' the things... I seem to remember using one of your portable browsers (probably either Opera or Vivaldi) to create QR codes of webpages. It was an inbuilt function of the browser but I dont recall ex...

I have been wanting to "De-Google" an android phone and it seems that the needed software is "adb" and "fastboot". ADB is "Android debug Bridge" that talks to the Android phone in a similar way to MTP software (but greater functionality) and "Fastboot&quo...

ROX calls it "List View"

Yes of course. Clever.
Thanks!

greengeek

Might be better to save minimal customisations (keyboard, timezone, etc etc) to an sfs (via nicos suite) and customise it into the iso and burning closed dvd.

Then forget about any session saving.

When I use ROX I find it annoying when windows resize and the display changes too much - so that files I have been working with jump to strange positions within the display window. I know I can force ROX to "never resize windows" - but it still causes some issues. In particular when I move...

So for banking and other sensitive personal use a better choice is to use a Linux distro that is not running as root user. There seem to be plenty of hacking examples impacting companies that already avoid using root user so being non-root user in your own computing is definitely no guarantee of sa...

nicOS didn't help me I've realized that there is no fully automatic way to remaster Puppy.

True.
Which is your preference - boot from CD/DVD - or boot from hard drive or usb stick?

greengeek

I have two concerns: 1. I've tried some Puppy flavours (Void, Fossa, Jammy) and I see that none of them prompts to remove media (DVD) before shutdown/reboot. How can I fix it. I.e. when my pupils turn-off computer DVD will remain in the drive and I don't want that. I'd have to reboot each machine a...

What is "Isolated Web Co" please?

greengeek

When ya start building GUIs, there's no end of "design" considerations to take into account, too, y'know..... Actually youve just reminded me of something amazing that SFR created on the old forum. I have just posted it as a future reference to try to learn some better gui skills: https:/...

greengeek

Not sure if there is already a GTK gui programming thread somewhere - but just wanted to post here an example that I would like to use as a reference for teaching myself how to make a gtkdialog gui that is wider (Landscape mode) rather than taller (Portrait mode). This example is from SFR in the old...

greengeek

Does GTK-dialog allow dual columns to be used? Good question. I confess I don't know the answer unfortunately. I certainly like the look of your yad guis - but I just try to do what I can with the basics that "come in the tin". Especially with something like Ozsouth's Fossa Mid and Fossa ...

Here is a small pet that offers a way to use the inbuilt webcam on a laptop without loading guvcview or other weighty software. (Uses the ffmpeg code that comes as standard in "Less") It loads two files into /root: - "mirrorcam" is a RoxApp that displays the output of /dev/video0...

greengeek

Test version v12: Good compatibility. In running compatibility tests I discovered that Fossa9.5 "Less" is a bit limited with which video formats it can handle and is a bit picky about how mp4 files are formatted. (It uses Palemoon as a default media player and needs pix-fmt yuv420p as the ...

greengeek

As per my previous post - selecting mpeg4 as the codec increases the chances of the output video being compatible across a wider range of devices. However - I also want to have the option of making file size the determinant factor - so this version DEFAULTS to the previous compatibility preferences ...

greengeek

I have been experimenting to improve reliability of video compatibility across different devices and players and this version is a test version to help with that. Worth a try as it seems quite good for me so far. (Will add to first post when I am fully happy with it) It adds extra output formats (ie...

ffmpeg -f alsa -ac 2 -i hw:5 -f v4l2 -i /dev/video0 -vcodec libx264 recording.mp4 -map 0:v? -vf "format=yuv420p" -f xv Camera_display_output ... Just out of curiosity, where did you dig that "format=yuv420p" up from? I'm still trying to figure out exactly what it IS specifying! ...

greengeek

I am not sure I fully understand how this is working so here is a supplementary question please: If I issue the following syntax: ffmpeg -formats > formats.txt ...I get a text file with meaningful contents. (showing the formats that ffmpeg understands) However, if I issue the following syntax (to fi...

greengeek

@greengeek - ffmpeg-sml .pet should work with non-usrmerge Ubuntu type pups (as well as Fossa64 pups) - it is actually from ScPup64-20.06, with lib paths adjusted. ozsouth - thanks for that. Can I ask a question about the ffmpeg in F95Mid please - am I correct in believing that it is the same ffmpe...

greengeek

Running nicely in Xenialpup64 on the Dell Latitude. Still needs the newer ffmpeg, however. And in Fossapup64 9.5 - Phil B's original - working as you would expect. Ffmpeg is up to the task here, so the newer JvS 'static' is not required..... :thumbup: Hi Mike, quick question about ffmpeg if i may -...

greengeek

One suggestion.....if I may? It might be prudent to also offer a greater range of framerates, too; lower framerates are one of the best ways to keep the overall size of recordings down. I'd suggest adding 10, 15 and 20.... I know 10's getting a bit low, but for long term monitoring of your property...

I've tried with another puppy (Triton-8 by petihar).
mp4 format is OK with it.
So tested and approved

Appreciate the testing & report - thank you!

greengeek

I have tested with yuyv422 and mjpeg : only mp4 doesn't work. May be, the ffmpeg version is too old, or not compiled to support mp4 format. It's not important. Thanks for testing. The following commands may be useful (They will create text files that list your codecs and formats) ffmpeg -codecs > c...

greengeek

Various combos all seem to work fine here;... 'Yuyv422'; yup. 'Mjpeg' is OK, too. 'Mkv', 'avi', 'mp4'.....all fine. That's great news, thanks for testing. I'm working on a modified MultiCam-portable; ffmpeg-based instead of mplayer, re-designed GUI, etc. I'll let you have the link when I'm happy wi...

greengeek

Released v08.
Improves the gui interrogation of formats & resolutions supported by selected usbcam.
Adds extra output formats.

(Please report any issues - much appreciated!)

greengeek

Since gxmessage allows input from stdin you can make this faster and simpler: ffmpeg -f v4l2 -list_formats all -i /dev/video"$USBCAM" 2>&1 | grep -Eo '(Raw|Compressed).*' | gxmessage -c -fn mono -file - I added the the -c and -fn mono options to center the dialog and make it more read...

Sorry, I missed this part of your post. I have edited my reply with a modified grep command. Should result in 2 lines: Raw : yuyv422 : YUYV 4:2:2 : 640x400 640x480 320x240 320x200 160x120 1280x800 1280x720 Compressed: mjpeg : Motion-JPEG : 640x400 640x480 320x240 320x200 160x120 1280x800 1280x720 T...

Later, will have another output format ?

If you have time please give this a try and tell me if this is helpful (s'il vous plait!! )

@greengeek :- Okay. After some research - and a fair bit of head-scratching! - here's a line that will record both video AND audio, AND give a real-time sync'd preview, too:- ffmpeg -f alsa -ac 2 -i hw:5 -f v4l2 -i /dev/video0 -vcodec libx264 recording.mp4 -map 0:v? -vf "format=yuv420p" -...
