Martin JS's questions

I have several videos in a folder;

~/Downloads/movie1.mkv
~/Downloads/movie2.mkv
~/Downloads/movie3.mkv

I would like to extract the bitrate for each file, and output the data into a single text file, or output list which I can copy and paste into a text file.

I have installed ffmpeg.
So, for example, the output of ffmpeg -i movie1.mkv is;

Metadata:
    encoder         : libebml v1.2.0 + libmatroska v1.1.0
    creation_time   : 2011-04-09T18:18:05.000000Z
  Duration: 00:04:27.71, start: 0.000000, bitrate: 10698 kb/s
    Stream #0:0(eng): Video: h264 (High), yuv420p(progressive), 1920x1038, SAR 1:1 DAR 320:173, 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc (default)
    Metadata:
      title           : movie1
    Stream #0:1(eng): Audio: dts (DTS), 48000 Hz, 5.1(side), fltp, 1536 kb/s (default)
    Metadata:
      title           : DTS-ES 5.1 @ 1509 Kbps
    Stream #0:2(eng): Audio: ac3, 48000 Hz, stereo, fltp, 192 kb/s
    Metadata:
      title           : Commentary
    Stream #0:3(eng): Subtitle: subrip
    Stream #0:4(eng): Subtitle: subrip

The "bitrate: 10698 kb/s" is the crucial part I am after here.
Let's pretend all three movies have the same bitrate.

I would like to extract the bitrate information from all three videos, and have them output as;

movie1.mkv 10698
movie2.mkv 10698
movie3.mkv 10698

How would I go about extracting and outputing this information in bulk?

I've been trying a combination of finding by file name, ffmpeg, and then | to grep. e.g ; find . -name "*.mkv" -exec ffmpeg -i "${1%.mkv}" | grep "bitrate:"

Current attempts;

1. The command

   ffmpeg -i movie1.mkv 2>&1 | grep bitrate | sed 's/bitrate: \(.*\), kb/\1/g'
   

   returns

   Duration: 00:04:27.71, start: 0.000000, bitrate: 10698 kb/s

2. The command

   find . -name "*.mkv" -exec ffprobe -v error -show_entries format=bit_rate -of default=noprint_wrappers=1:nokey=1 "${~/Downloads/1%.mkv}"  ';`'
   

   returns

   ~/Downloads/1%.mkv: No such file or directory ~/Downloads/1%.mkv: No such file or directory ~/Downloads/1%.mkv: No such file or directory

I feel that I'm close here, and that there's just something wrong with the find and recalling the output of find into ffprobe.

I have several movies in a folder.

For example:

~/Downloads/Movies/Movie A (1998).mkv  
~/Downloads/Movies/Movie B (1999).mkv  
~/Downloads/Movies/Movie C (2000).mkv

I would like to put each file into its own folder, and name the folder identical to the file name. I have many files, so I would like to be able to do this in a batch if possible.

For example:

~/Downloads/Movies/Movie A (1998)/Movie A (1998).mkv
~/Downloads/Movies/Movie B (1999)/Movie B (1999).mkv
~/Downloads/Movies/Movie C (2000)/Movie C (2000).mkv

I have tried to use the bash command on this page

find . -name "*.mkv" -exec sh -c 'mkdir "${1%.*}" ; mv "" "${1%.*}" ' _ {} \;

However, I get the error message:

mv: cannot stat '': No such file or directory

The folder is created correctly, but the command fails to move the file into the folder, and I get the above error.

Which part of

; mv "" "${1%.*}" ' _ {} \;

is incorrect, and how so?

Also, if there are other commands or scripts you think would do the job, that would be appreciated.

I like to compartmentalize my internet browsing. I use one browser for work related stuff, one browser personal banking and bills, and another browser for general social related stuff like online forums and youtube.

Until now, I've simply used a combination of the Pre-installed Firefox, Chromium, and Waterfox. However, I much prefer to use the latest Firefox for all three. I am not interested in using different profiles for the one browser, as I like to have all three open at the same time.

EDIT: See Bruni's answer below. Three separate profiles is in fact the way to go, using the -no-remote function.

I recently used this script by Davide Airaghi to create 2 portable versions of firefox. I moved the two portable firefox folders to ~/firefox-work and ~/firefox-social. The pre-installed version is what I use for banking and other personal stuff.

I have all three running at the same time, and they work fine, however in my Plank launcher, they all show up under the same icon. Is there any way I can launch each of these portable firefox apps and the pre-installed app, and have them be shown in Plank as three separate applications?
