I have about 300 videos, on a Debian server, stored in the following manner:
/mediaroot/1/m32.mp4
/mediaroot/2/m421.mp4
/mediaroot/n/mx.mp4
They all need to be deinterlaced, and I want to do it with FFmpeg.
With the assistance of another helpful sole, I have reached a somewhat tolerable result with the following steps:
extract audio
transcode video, example
ffmpeg -y -i m148.mp4 -pix_fmt yu
I stream stuff quite often.I'd use FFmpeg for that, which can output to nearly anything.I think you can stream through rtp for a very basic link: http://ffmpeg.org/trac/ffmpeg/wiki/Stre … tstreamingI personnaly use this command:ffmpeg \
-f x11grab -s 1920x1080 -r 30 -show_region 1 -i :0 \
-f pulse -ac 2 -ar 44100 -i default \
-isync \
-vcodec libx264 -b:v 700k -tune zerolatency -preset fa
I'm trying to stream the video and audio a USB webcam using avconv (or ffmpeg) using just port 8080 over a network.
I can successfully stream audio using the following command:
Code:
avconv -f oss -ar 8000 -ac 1 -i /dev/dsp1 -acodec mp2 -f rtp rtp://172.17.2.2:9090
and VLC will read it just fine, with maybe a 1 second delay.
I can successfully stream video using:
Code:
avconv
I have no idea. I did a lot of googling and lots of talk about what it is in ffmpeg and not much examples.
Is anyone familiar with ffmpeg? Im trying to get a screenshot of my htc one x in recovery and ddms wont work. So I tried to pull the dev/graphic/fb0 file and I have successfully pulled it but i'm unable to get ffmpeg to convert it to a picture format like png or jpeg.
I am using KDE 4.9.2 on Kubuntu 12.04. I have a problem with the mic where I can hear my voice on the speakers but cant seem to record anything (tried ffmpeg and audacity)
The Code which I used for recording in ffmpeg
Code:
ffmpeg -f alsa -i pulse -f x11grab -r 30 -s 1366x768 -i :0.0 -acodec pcm_s16le -vcodec libx264 -preset ultrafast -threads 0 output.mkv
I've written an article about some tricks you can do with ffmpeg, in today's article, I will show you another trick - compressing avi and mp4 video files with a simple command with a only a small loss in video quality.
If you dont have ffmpeg already installed, you can run this command to install it in Ubuntu and other Debian-based distros:
sudo apt-get install libav-tools
To compress an avi
I am trying to stream to twitch.tv using the following ffmpeg command http://www.creativetux.com/2012/11/s...ith-linux.html
and the ffmpeg preset is quality "medium". How can I find out what the bitrate is for that preset? Can someone please post all the libx264 presets and their settings for each preset. I can't find them anywhere. Thanks!
Main code: ffmpeg -i 2269801.avi -threads 0 -vcodec libx264 -b 900k -acodec libfaac -ar 44100 -ab 96k -ac 2 earthgirlsareeasy1.mp4
