  • Rewrap an AVCHD (MTS/M2TS) video as MOV

    This *does not change the video encoding*, so it's fast (almost purely I/O-bound) and results in a file of nearly the same size. However, OSX (and possibly other programs) will more easily play/seek the file when wrapped as MOV. For example, you can QuickLook the resulting file. This basically does the same as the commercial ClipWrap program, except using the free program ffmpeg. Show Sample Output

  • Remove excess noise from a set of mp4 videos.

    Full command: for f in input/*; do BN=$(basename "$f"); ffmpeg -i "$f" -vn "temp/$BN.flac"; sox "temp/$BN.flac" "temp/$BN-cleaned.flac" noisered profile 0.3; ffmpeg -i "$f" -vcodec copy -an "temp/$BN-na.mp4"; ffmpeg -i "temp/$BN-na.mp4" -i "temp/$BN-cleaned.flac" "output/$BN"; done This was over the 255 character limit and I didn't feel like deliberately obfuscating it. 1. Create 'input', 'output' and 'temp' directories. 2. Place the files that you want to remove the hiss/static/general noise from in the input directory. 3. Generate a noise reduction profile with sox using 'sox an_input_file.mp4 -n trim x y noiseprof profile', where x and y indicates a range in seconds that only the sound you want to eliminate is present in. 4. Run the command.

  • Convert SWF to video

    This will dump a raw BGRA pixel stream and WAV which must then be converted to video: ffmpeg -f rawvideo -c:v rawvideo -s 1280x720 -r 12 -pix_fmt bgra -i "${i%.*}".bgra -c:v libx264 -preset veryslow -qp 0 -movflags +faststart -i "${i%.*}".wav -c:a libfdk_aac -b:a 384k "${i%.*}".mp4 ; rm "${i%.*}".bgra "${i%.*}".wav Our example generates an x264/720p/12fps/AAC best-quality MP4. To get dump-gnash, first install the build-dependencies for gnash (this step is OS-specific). Then: git clone http://git.savannah.gnu.org/r/gnash.git ; cd gnash ; ./autogen.sh ; ./configure --enable-renderer=agg --enable-gui=dump --disable-menus --enable-media=ffmpeg --disable-jemalloc ; make

  • replace audio track in a video file

    The "map" may be different depending on the .wmv file. run `ffprobe` to see which is the video-track in the .wmv file usually this is "0.0". Stream #0.0: Video:... Stream #0.1: Audio: .. and "1.0" corresponds to the 2nd input file - your new audio. You may want to add "-acodec wmav2" and "-ar 128k" options for 128kbit/s Windows Media Audio 2 or whatever audio-codec/quality your want. `ffmpeg -codecs | grep "EA"` gives you a list of available codecs for Encoding Audio. Try using '-sameq' instead of '-vcodec copy' (re-encode the video with same quality rather than a bit-exact copy - this often solves muxing issues but will cause a small loss of either video quality or increased bandwidth). and also try a different output format eg. 'new_video.avi' or '..mov' instead of 'new_video.wmv'. you may need both, this should work: ffmpeg -i vid.wmv -i aud.wav -sameq -map 0.0 -map 1.0 output.avi

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

cycle through everything sox knows how to read, playing only the first three seconds
I wasted two hours reading the sox documentation and searching on the web for the format of some obscure fscking sound sample, and then finally came up with this. This plays only the first three seconds of your unknown formatted sound file using every one of sox's built-in filetypes. If you don't get an exact match, you may get close. . I could not fit every single type in and keep it under 127 characters, so you will have to replace "..." with the full list obtainable by `$ sox --help` (or try `Show sample output`) . note: /usr/bin/play should be linked to sox on most systems.

kill all foo process
Kill all processes with foo in them. Similar to pkill but more complete and also works when there is no pkill command. Works on almost every Linux/Unix platform I have tried.

List out classes in of all htmls in directory
Lists out all classes used in all *.html files in the currect directory. usefull for checking if you have left out any style definitions, or accidentally given a different name than you intended. ( I have an ugly habit of accidentally substituting camelCase instead of using under_scores: i would name soemthing counterBox instead of counter_box) WARNING: assumes you give classnames in between double quotes, and that you apply only one class per element.

Hide or show Desktop Icons on MacOS
Hides all Files and Folders on the MacOS Desktop. To show files and folders, type "true" instead of "false". "Finder" at the end is case sensitive, "finder" doesn’t work

This is flatcaps tweaked command to make it work on SLES 11.2

print crontab entries for all the users that actually have a crontab
This is how I list the crontab for all the users on a given system that actually have a crontab. You could wrap it with a function block and place it in your .profile or .bashrc for quick access. There's prolly a simpler way to do this. Discuss.
