Keeping control of your media in your hands

FfmpegInterop UWP C#
10 octobre 2016, par Sean RyanI successfully build ffmpeg for ffmpeginterop and I added reference nodes to the dll in the .csproj file, however when I run my project as soon as FFmpegInteropMSS.CreateFFmpegInteropMSSFromStream(avStream, false, false) is executed I’m hit with a System.IO.FileNotFound exception. I did paste the ffmpeg dlls with the ffmpeginterop and also tried in the project dir with copy to output, no change. Any ideas would be greatly appreciated.

Change AVI creation date with ffmpeg ?
1er novembre 2016, par brockAs far as I can tell the following ffmpeg command should copy all existing metadata in the input file to the output file and modify the specified field in the output file :
ffmpeg -i VID_20130502_220104.avi -metadata creation_time="2013-05-02 22:01:04" -codec copy VID_20130502_220104-2.aviInstead, it seems to strip all metadata from the output file. Here is the output of a few commands. I am going nuts. I think this should work, but why is it not ?
Command to edit the creation time :
ffmpeg -i VID_20130502_220104.avi -metadata creation_time="2013-05-02 22:01:04" -codec copy VID_20130502_220104-2.avi

ffmpeg udp live stream publish to rtmp
2 juin 2016, par PilskalnsI need to make this chain :
JVC HM650—UDP—>localhost—>ffmpeg(copy stream)—>nginx-rtmpOn input I have UDP stream from camera (udp ://@:35501) and I need it to publish to rtmp server (nginx with rtmp module). Apart everything works - I can play input on VLC, I can stream from FMLE to nginx etc. Except, this is my first time with ffmpeg and I can’t get it work. So :
This is best i have got :
C:\ffmpeg\bin>ffmpeg -re -i udp://@:35501 -f flv "rtmp://192.168.1.17/live/live" -loglevel debug

C:\ffmpeg\bin>What is wrong with ffmpeg configuration ?
SOLUTION :
The
ffmpegwas listening on wrong version of UDP protocol :Even IPv6 is disabled on network cards, internally in system, using
@allowed ffmpeg listen at UDPv6.By using
127.0.0.1tells ffmpeg to use clean UDP.Thanks, @thomas to make me think differently !
