Les tâches Cron régulières de la ferme
1er décembre 2010, parLa gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.

How to extract a video snippet from a video file that is being written in by ffmpeg in realtime
31 juillet 2020, par alex.bAt the moment i am recording a LIVE stream video from youtube with youtube-dl (https://github.com/rg3/youtube-dl)



The command i use for this :



youtube-dl --id -f 92 https://www.youtube.com/watch?v=VYlQJbsVs48




92 is a format code that i got after executing a command to get the formats, that gave me this list :



format code extension resolution note
140 m4a audio only DASH audio 144k , m4a_dash container, aac @128k (48000Hz)
141 m4a audio only DASH audio 272k , m4a_dash container, aac @256k (48000Hz)
160 mp4 256x144 DASH video 124k , 15fps, video only
133 mp4 426x240 DASH video 258k , 30fps, video only
134 mp4 640x360 DASH video 616k , 30fps, video only
135 mp4 854x480 DASH video 1116k , 30fps, video only
136 mp4 1280x720 DASH video 2216k , 30fps, video only
137 mp4 1920x1080 DASH video 4141k , 30fps, video only
151 mp4 72p HLS
132 mp4 240p HLS
92 mp4 240p HLS
93 mp4 360p HLS
94 mp4 480p HLS
95 mp4 720p HLS
96 mp4 1080p HLS (best)




This is creating a file called VYlQJbsVs48.mp4.part that gets bigger and bigger of course.



Is there a way to extract a video snippet from that live stream or form the part file ? Or maybe there is a better way of doing this ?



What i have noticed is that if i force quit iTerm2 while youtube-dl is running the .part file it creates wont contain any index information (something to do with an moov atom not being present in the mp4 file - which is the information about the number of frames and other things - metadata i think), so it makes me think i cannot extract from the file.



Maybe if there would be a way that youtube-dl can write the index information at all times or maybe another way that i can record the live stream and get video snippets while its recording.



I forgot to mention i am doing this on OSX Yosemite. I have FFMPEG installed with homebrew and youtoube-dl



I am more than happy to try stuff on UBUNTU if there is a solution.



Any help would be greatly appreciated.



Thank you.

FFMPEG Overlay video on top of another video
19 mai 2014, par James Blackbj BlackburnI have looked through all the questions on this on stackoverflow but none of the answers worked for me.
I have a screen recorded video in mp4 and another video recorded from a webcam in mp4. I want to overlay the webcam video over the top left of the screen recorded video.
I think I finally found the right command line for doing this but when I step through the ffmpeg process it freezes when it reaches " handler_name :SoundHandler".
Here is my command line :
string overlayPosition = "movie=" + '"' + _videoFile.FileName + '"' + "[inner]; [in][inner] overlay [out]";
string overLayCommand = "-i " + '"' + videoList[0].Path + '"' + " -vf " + '"' + overlayPosition + '"' + + '"' + " C:\\Users\\james\\output.mp4" + '"';Does anyone know what I am doing wrong ? I’ve managed to trim audio and video, crop video, join sound, join video, and join sound and video but cannot get overlay to work :(.
