Image Files
If you want to change image files via terminal, ImageMagick is a good choice.
Resize Images to a maximum resolution
convert "YourOldPicture.jpg" -resize 1600x1600 "YourNewPicture.jpg"
Create a Black-and-white picture and compress it
djpeg "YourOldPicture.jpg" | ppmtopgm | cjpeg -qual 70 >"YourNewPicture.jpg"
Rename Pictures
rename -n ’s/\.jpg$/\.JPG/’ *.jpg
Audio Files
flac2mp3
- Convert flac to mp3 audiofile:
ffmpeg -i file.flac -ab 320k -ac 2 file.mp3
Normalize Audio
Give all mp3 songs the same sound level (it’s called Audio normalization)
mp3gain -a *.mp3
Merge mp3 audio files to one
mp3wrap merged.mp3 one.mp3 two.mp3
fade in/out filter
details see here: https://ffmpeg.org/ffmpeg-filters.html#afade
- Fade in first 15 seconds of audio:
ffmpeg [...] -afade=t=in:ss=0:d=15 [...]
- Fade out last 25 seconds of a 900 seconds audio:
ffmpeg [...] -afade=t=out:ss=875:d=25 [...]
or try sox:
this command will
- trim out from Position 45 sec. the next 30 seconds (0:45.0 30) and
- fade the first 5 seconds (0:5) and the last 5 seconds (0 0:5) and
- convert from wav to mp3
sox infile.wav outfile.mp3 trim 0:45.0 30 fade h 0:5 0 0:5
cut / crop audio
try sox (see above) which strips, fades in and out in one command.
to strip the 1st 30 sec. of an audio file
ffmpeg -ss 30 -acodec copy -i inputfile.mp3 outputfile.mp3
to only get the 1st 30 sec. of an audio file
ffmpeg -t 30 -acodec copy -i inputfile.mp3 outputfile.mp3
wav2mp3
- Convert all *.wav-files in one folder two *.mp3-files and remove the *.wav-files:
for i in *.wav;do lame "$i" "${i%wav}mp3"; rm "$i"; done
- Convert all *.wav-files in one folder two *.mp3-files and move mp3's to mp3-folder:
for i in *.wav;do lame "$i" "${i%wav}mp3"; mkdir -p mp3; mv "${i%wav}mp3" mp3/; done
mp32wav
convert mp3 to wav
mpg123 -w output.wav input.mp3
mp32ogg
convert mp3 to ogg
mpg123 -w - ./FILE.mp3 | oggenc -q 3.00 -o ./FILE.ogg -
Video Files
For quite a lot purposes is the command line tool FFmpeg with its lots of options a good choice. For others might MEncoder be better. You might also want to install some codecs first:
sudo apt-get install libavcodec-extra-52 libavdevice-extra-52 libavformat-extra-52 libavutil-extra-50 \ libpostproc-extra-51 libswscale-extra-0 libavcodec-unstripped-52 ubuntu-restricted-extras
DVD to mp4
If you have a DVD or DVD.iso file create a single .VOB file
mplayer dvd://n -v -dumpstream -dumpfile /var/tmp/dvd.vob
If 'dvd://n' detects the wrong stream locate longest stream and replace 'n' by stream number
$ lsdvd |grep Longest Longest track: 01
If it's an ISO file replace 'dvd://n' by: -dvd-device /path/to/dvdfile.iso
Now convert .vob to mp4:
cat /var/tmp/dvd.vob | ffmpeg -i - -codec:a copy -codec:v libx264 /var/tmp/dvd.mp4
strip audio from video
ffmpeg -i input_file.mp4 -vcodec copy -an output_file.mp4
replace/add audio in/to a video
1st of all get the streams
$ ffmpeg -i video-with-audio.avi -i audio.mp3 [...] Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'video-with-audio.avi': Duration: 00:01:13.29, start: 0.000000, bitrate: 17022 kb/s Stream #0.0(eng): Video: h264, yuv420p, 1920x1080, 90k tbr, 90k tbn, 180k tbc Stream #0.1(eng): Audio: aac, 48000 Hz, stereo, s16 Input #1, mp3, from 'audio.mp3': Duration: 00:00:46.52, start: 0.000000, bitrate: 192 kb/s Stream #1.0: Audio: mp3, 44100 Hz, stereo, s16, 192 kb/s At least one output file must be specified
now you can see:
- stream 0.0 video-stream in the avi
- stream 0.1 audio-stream in the avi
- stream 1.0 audio-stream (the mp3 file)
now, to get the video with the mp3-file as audio, do:
ffmpeg -i video-with-audio.avi -i audio.mp3 -map 0.0 -map 1.0 -acodec copy -vcodec copy output.avi
here you tell ffmpeg to map streams 0.0 and 1.0 into the new output.avi
Merge many video files to one
cat One.mpg Two.mpg Three.mpg | ffmpeg -f mpeg -i - -vcodec copy -acodec copy "Merged.mpg"
avi2mpg
ffmpeg -i "Original.avi" "New.mpg"
flv2mpeg
- Convert FLV to MPG file:
ffmpeg -i video.flv video.mpg
- Convert MPG to FLV file:
ffmpeg -i video.mpg video.flv
this works for avi, too!
flv2avi
- Convert FLV to AVI file:
ffmpeg -i video.flv -ar 22050 -b 2048k video.avi
- Convert AVI to FLV file:
ffmpeg -i video.avi video.flv
avi2avi
- -)
xvid2divx
relabel file from XviD to DivX 5
needs no recoding just re-label it as DivX
cfourcc -u DX50 -d DX50 "$file"
flv2mp3
- Convert FLV to mp3 audio file:
ffmpeg -i video.flv -ab 192k output.mp3
*2flv
to convert some format to flv
for webstreaming there is some more work to do, which i will describe here...
flv streaming in apache:
- get the apache module: HERE
- compile with apxs2 (debian) btw. apxs (RH-related distros)
apxs2 -i -c ./mod_flvx.c
- load into apache2:
cat /etc/apache2/mods-available/flvx.load # flv-streaming plugin # source: http://people.apache.org/%7Epquerna/modules/mod_flvx.c # build: apxs -c -i ./mod_flvx.c LoadModule flvx_module /usr/lib/apache2/modules/mod_flvx.so AddHandler flv-stream .flv
- enable module:
a2enmod flvx
- restart apache
- create flv:
ffmpeg -i ~/any.supported.format.eg.mp4 -b 4000000 -r 25 -s 800x600 ~/output-file.flv
- perhaps try around with b-frames: -b_qfactor 4.0 - see man ffmpeg
- Add pseudostreaming meta data to the file:
flvtool2 -Up output-file.flv
- if you want to preserve a file WITHOUT meta data for webstreaming create a backup
flvtool2 will inject metadata into actual file!
- if you want to preserve a file WITHOUT meta data for webstreaming create a backup
swf2avi
requires package: pyvnc2swf
vnc2swf-edit -o output.flv input.swf ffmpeg -i input.flv output.avi
mov2avi
ffmpeg -i movie.mov -acodec copy -vcodec copy movie.avi
mp42mpg
ffmpeg -i "Original.mp4" -target ntsc-vcd "New.mpg"
mp42avi
ffmpeg -i filename.mp4 -vcodec mpeg4 -acodec ac3 -ar 48000 -ab 192k output.avi
or
-acodec libmp3lame
mp42mp3
mp42wav
extracts audio from an mp4 video file
mplayer source.mp4 -ao pcm:file=tmp.wav lame -b 128 -q 2 tmp.wav final.mp3
mod2avi
?
vcd2avi
mencoder vcd://2 -o "New.avi" -oac copy -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=2000
dvd2avi
to do this you will have to run the following command-tripple:
- get the black border dimensions to cut them off
- run pass 1 with mencoder to create the 'divx2pass.log', which is needed by pass 2 run
- run pass 2
1)
play TRACK 1 (dvd://1), chapter 3
mplayer dvd://1 [-dvd-device /path/to/dir or /dev/cdrom] -chapter 3 -vf cropdetect ... [CROP] Crop area: X: 0..719 Y: 70..505 (-vf crop=720:432:0:72).0 ...
2)
do the 1st pass with mencoder
set -vf crop= to the value mplayer puts out to console
while running the 1st command
mencoder dvd://1 [-dvd-device /path/to/dir or /dev/cdrom] \ -vf crop=720:432:0:72,scale=704:304 -ovc xvid \ -xvidencopts bvhq=1:chroma_opt:quant_type=mpeg:bitrate=658:pass=1 \ -oac copy -o /dev/null
- scale=704:304 ==> nice for 16:9
if you change that, be sure the values both are dividable by 16!! - if you dont want to use CD (700MB) to backup that film try using a bitrate ob 1200 or 1400 instead of 658
- a bitrate of 1600 creates a 2GB file out of 4.6GB-DVD and has acceptable quality...
3)
2nd pass run...
be sure the divx2pass.log file is in CWD where you start mencoder...
mencoder dvd://1 dvd://1 [-dvd-device /path/to/dir or /dev/cdrom] \ -vf crop=720:416:0:80,scale=704:304 -ovc xvid \ -xvidencopts bvhq=1:chroma_opt:quant_type=mpeg:bitrate=658:pass=2 \ -alang de -oac mp3lame -lameopts br=96:cbr:vol=6 -o FILM.avi
ogv2avi
mencoder "Original.ogv" -ovc xvid -oac mp3lame -xvidencopts pass=1 -o "New.avi"
wmv2mpg
aspect=16/9 should eventually be changed to 4/3 or other aspects
mencoder -of avi -ofps 25 \ -oac mp3lame -lameopts cbr:br=112:aq=3:mode=0:vol=0 \ -vf hqdn3d,softskip,harddup \ -ovc xvid \ -xvidencopts bitrate=501:max_key_interval=37:aspect=16/9:turbo:nochroma_me:notrellis:max_bframes=0:vhq=0 \ Original.wmv \ -o New.avi
mkv2avi
mencoder "Original.mkv" -ovc lavc -lavcopts vcodec=mpeg4:vhq:vbitrate=6000 -oac mp3lame -lameopts vbr=3 -o "New.avi"
or use ffmpeg
ffmpeg -i INPUT_FILE -f mp4 -r 23.976 -vcodec libx264 -s 1280x720 \ -b 3000kb -aspect 16:9 -flags +loop -cmp +chroma -deblockalpha 0 \ -deblockbeta 0 -maxrate 3500k -bufsize 4M -bt 256k -refs 1 \ -bf 3 -coder 1 -me_method umh -me_range 16 -subq 7 \ -partitions +parti4x4+parti8x8+partp8x8+partb8x8 -g 250 \ -keyint_min 25 -level 30 -qmin 10 -qmax 51 -qcomp 0.6 -trellis 2 \ -sc_threshold 40 -i_qfactor 0.71 -acodec libfaac -ab 384kb -ar 48000 -ac 2 OUTPUT.MP4
