Keenan J. Troll also suggested some other interesting method for hashing audio - as one. Without grouping samples together. Just one hash for the whole audio block. His original command included video container structure data in the output. I've removed this by setting the output format to raw sampl...

Based on some inspiration and input from Keenan J. Troll, here's a recipe that does 4 things in one: Rewrap (without transcoding) to MKV Adjust (tech-)metadata here too. This is optional, but very handy. The example here shows setting interlacing flags. Generate framemd5 for video source Generate fr...

[PROBLEM] I was trying to generate framemd5 for video and audio in one step: $ ffmpeg -i bars.mov -map 0 -c copy -flags +ildct+ilme -field_order bb rewrap.mkv \ -an -f framemd5 bars.video.framemd5 \ -vn -c:a pcm_s24le -filter_complex "asetnsamples=n=48000" -f framemd5 bars.audio.framemd5 ...

This is actually based on the steps described on instructables.com: Raspberry Pi As Wake on LAN Server . 1) Install "etherwake" package: $ apt install etherwake In my network, I've got all ethernet MAC IDs configured in my ISC DHCP configuration (Raspbian/Debian), so I'm using that "d...

Everything here is optional! In this posting, I'm just collecting issues I encountered during trying to fix this. I hope it helps others to find this thread and hopefully the above mentioned solution works for them too :D # Trying to load the module manually, after install with ubuntu's proprietary...

[PROBLEM] After amost recent update of X11 and kernel packages on a Xubuntu 16.04.6 system, the graphics card setup regressed: From proper working Dualscreen (FullHD + 1280x1024 resolution) to single monitor at 800x600 pixels :shock: :? I know that a proprietary Nvidia driver was used before, but I...

Although audio + video works fine now in VLC, there's a warning/error message in the console in the background:

vdpau_avcodec generic error: decoder profile not supported: 8

[PROBLEM] After switching to Nouveau drivers for an Nvidia graphics card (see below) everything seems to be working fine (including Dualscreen+offset, etc) - but VLC doesn't play any videos: Black screen. No error message (except in the console. See below). But sound is playing. Here's info about t...

This HowTo explains quickly how to get the full date/time information for a directory listing in the shell. By default, "ls" on GNU/Linux (e.g. Debian, Ubuntu, etc) only gives a short view of date and time for files and folders: ls-dirlist_normal.png When a timestamp is further in the past...

In this HowTo, I'll describe how to set up an OpenVPN connection to a server that is accessible only through an SSH port forward. This config will only create a single point-to-point connection. No subnet routing, just 2 IPs: Server + Client. The assumed scenario here is Ubuntu/Debian based and was ...

Here's one way to check the current folder, with the data in the fixity textfile "MD5DEEP.md5": $ hashdeep -l -e -vvv -r -a -k MD5DEEP.md5 . Parameters: -l: Relative paths mode. Otherwise you'll only get "file moved" messages ;) -e: Estimate time. Shows a progress indicator. Must...

[PROBLEM] I wanted to enable GPU processing in kdenlive (on Xubuntu 16.04, 64bit), but got this error message instead: Cannot initialize Movit's GLSL manager, please disable Movit :( [SOLUTION] Haven't tried it yet, but starting kdenlive in a terminal, gave me the following information: Shortcut fo...

You may find or search this under "md5deep", but the command - as well as its package - was renamed/superseeded by "hashdeep". Where "md5sum" creates a textfile per folder, the command "hashdeep" can be used to create fixity information for a whole subfolder s...
