A quick note on how to boost the audio stream in a video using the volume filter in ffmpeg
#;For newer versions of ffmpeg ffmpeg -i input.mkv -filter:a "volume=4.0" output.mkv; #For older versions of ffmpeg (we use multiples of 256) ffmpeg -i input.mkv -vol 1024 -vcodec copy output.mkv;
Using the above command we were able to make the audio LOUDER!
Just some quick notes on how to install and use VOSK on Ubuntu 18.04 LTS.
pip3 install voskffmpeg create input audio files ffmpeg -i video.mkv -c:a pcm_s16le -ac 1 output.wavoutput.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 48000 Hzpython3 ./test_simple.py output.wavWhat would happen of the Cataclyst had gone off inside the Orb of Osuvox? Also, what would happen if the Cataclyst were to go off on the outside perimeter of the shield created by the Orb of Osuvox? Would the barrier of the orb take the damage or would the Cataclyst prevail?
Recently, a postfix mail server running on Ubuntu gave us the following error while trying to send an email to Bob:
Jun 16 17:02:03 gateway postfix/smtp[23522]: ED3799A0D27: to=[email protected], relay=none, delay=0.02, delays=0.01/0.01/0/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=smtp.gmail.com type=AAAA: Host not found, try again)
After several attempts like changing the protocol (inet_protocols) to IPv4 (since AAAA is an IPv6 A-record) in /etc/postfix/main.cf and so on we could not get it running.. We restored the configuration file to its original and then we restarted the service:
sudo service postfix restart;
It worked!…. no idea why..
