Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur
8 février 2011, parLa visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

RTMP video streaming client without showing the video just need extensive log
6 août 2016, par AmirI set up an RTMP video streaming server in a cloud environment for research purposes. On another VM in the cloud, I want to use a client to do some experiments. I have tried some different video player like VLC and FFplay but they are keep playing the video in the shell. As it is in the command line environment and to make sure my experiments are not biased with human errors, I need an RTMP video streaming client that just receives the stream as if it wanted to play it and log everything, for instance, if the playback stops due to buffering, average buffer size, etc.
Thanks

How to extract video clip from larger video based on specific time and duration
26 juillet 2022, par user19019404I have video clips that get created. Each video is recorded for 5 minutes and starts at a time e.g. 10:01:20 to 10:06:19 then the next video from 10:06:20 etc. These videos are recorded at a specific frame rate, be it 5 frames or 30 frames (its dependent on the platform making the recording). The net result is NOT a 5 minute video clip but might be a 2 minute video clip (where everyone moves very quickly in the view as a result of the frame rates). I cannot restrict a 1 to 1 recording as these are generated by external systems.


I need to extract specific portions out of the video. For example I need to extract from 10:03:10 to 10:03:35 (25 seconds). This would equate to 10 seconds into the video up to 14 seconds into the video, in those 4 seconds of video, 25 real world seconds are displayed.


My question is do you have any guidance as to how I can calculate that each second of recording actually means 10 or 12 seconds in real life, therefore go to this frame and record to this frame for example.


I have been looking at cv2.CAP_PROP_FPS to get the video frame rates, CAP_PROP_POS_MSEC and CAP_PROP_FRAME_COUNT and believe the answer might lie there, but not sure.


The thinking being if I work out the frame rate of the video, the total frames then I can divide the one by the other to get to how many frames make up real world seconds (this is where I fail). This way I can run from frame to frame as a result.


Thank you

FFMPEG trouble with concatenating Video + Video[+Audio]
27 avril 2022, par umpyloompyi need to concatenate (1-st Video) without changes + (2-nd video with replaced audio), but my command skips 2-nd video (but duration shows normally)

ffmpeg.exe -y -i "1st.mp4" -i "2nd.mp4" -i "audio.mp3" -map 0:v:0 -map 1:v:0 -map 1:a:0 -c copy "output"
