amix parameter decreases volumes of each input track to avoid clipping of the result track. Try this to prevent this behaviour: ffmpeg -y -i payload.mp2 -i bed.mp2 -filter_complex “[0]volume=2[a];[1]volume=2[b];[a][b]amix=inputs=2:duration=shortest:dropout_transition=0” payload_plus_bed.mp2 Advertisements
# ffmpeg -loop 1 -r ntsc -i “IMAGE.jpg” -i “AUDIO.mp3” -acodec aac -vcodec libx264 -preset fast -threads 0 -shortest “VIDEO.mov”
Problem: You have a lot of files with strange encoded names like: Your filesystem, transfered from older samba servers, contains files with windows-1252 encoded characters ibn their names, who won’t be displayed by samba. Solution: Use the magic convmv tool: # convmv –notest -r -f windows-1252 -t utf-8 /path/to/your/data Thank you, Bjoern JACKE!
Problem: You add a room with ejabberdctl. # ejabberdctl create_room testroom conference.xmpp.inbbradio.de localhost You list all rooms with ejabberdctl. # ejabberdctl muc_online_rooms global You delete a room. # ejabberdctl destroy_room testroom conference.xmpp.inbbradio.de You list all rooms with ejabberdctl. # ejabberdctl muc_online_rooms global You restart ejabberd # ejabberdctl restart You list all rooms with ejabberdctl. # […]
For each character in string do # IN=”\\”;printf -v OUT ‘%%%02x’ “‘$IN”; echo $OUT or # echo “this & that” | perl -MURI::Escape -ne ‘chomp;print uri_escape($_),”\n”‘
