Linux motion program on a7

sure enough, after a reboot ununtu named my /dev/video devices differently.

using
udevadm info -a -p $(udevadm info -q path -p /class/video4linux/video0)
udevadm info -a -p $(udevadm info -q path -p /class/video4linux/video2)

I found they are different cards.
ATTR{card}==”118″
ATTR{card}==”77″

The Swarm project is a solution to perform real browser to browser live P2P broadcasting.

Browser testing is being done in a lab in Delaware, USA and the Azure cloud (east & west US, southeast Australia, south Brazil, north & west Europe, east Asia, south Korea, and west India). Machines include Windows 7, 8, 10, Server 2012, and Linux Centos 7.

Background
I’ve been doing live P2P broadcasts since 2006. Every time I get involved with a solution the provider has jumped ship or changed their TOS to own my content if I use them. I don’t own the content so I cannot I accept that TOS.

Mad Buffalo Productions was created because I grew disgusted with the way big media has stolen our music, our movies, our art. When I say ‘our’, I mean us humans. It is ridiculous to me that music that is 40 years old is still owned by big corporations. Did you know that Time Warner owns ‘Happy Birthday to You’, and we won’t legally be able to sing it on stage until the year 2030 unless we pay them off? Update: This was invalidated in 2015 by a federal judge.

Mad Buffalo Productions is the company responsible for the promotion of the artists, and My Delaware TV is the technical ‘get it out to the masses’ entity.

Assuming the codecs are the same you create a file (example mylist.txt):

file ‘/path/here/file1.avi’
file ‘/path/here/file2.avi’
file ‘/path/here/file3.avi’

Then pass that file to ffmpeg

ffmpeg -f concat -i mylist.txt -c copy x.avi

You can use this command to make the list:

ls *.avi | while read each; do echo “file ‘$each'” >> mylist.txt; done

to convert

ffmpeg -i example.mp4 -f webm -c:v libvpx -b:v 1M -acodec libvorbis example.webm -hide_banner
ffmpeg -f concat -i mylist.txt -f webm -c:v libvpx -b:v 1M -acodec libvorbis oupu.webm -hide_banner
ffmpeg -f concat -i mylist.txt -strict -2 -c:a aac -b:a 128k -c:v libx264 -crf 23 -y output.mp4

to add some keyframes
-x264-params keyint=15:min-keyint=15
ffmpeg -f concat -i mylist.txt -strict -2 -c:a aac -b:a 128k -c:v libx264 -x264-params keyint=15:min-keyint=15 -crf 23 -y output.mp4
