  • FFMPEG : Obtain the system time corresponding to each frame present in a video

    18 mai 2022, par User

    I am currently recording the screen using the below command on Windows 10 system,

    



    ffmpeg.exe -loglevel quiet -f gdigrab -framerate 30 -i desktop -vf mpdecimate,setpts=N/FRAME_RATE/TB -vcodec libx264 -pix_fmt yuv420p -preset slow -crf 0 -threads 0 nodups.mkv


    



    If I record a video for 5 mins, where 4 minutes out of it is idle. The final video obtained is only 1 minute. I want to know the system time corresponding to a specific frame from this 1 minute video. 
I tried making use of the command to obtain the frame information from this 1 minute video for 40th frame like : ffmpeg -i nodups.mkv -vf select='eq(n,40)',showinfo -f null -
This outputs me

    



    [Parsed_showinfo_1 @ 000002455fce5dc0] n:   0 pts:   1333 pts_time:1.333   pos:   158601 fmt:yuv420p sar:0/1 s:1600x900 i:P iskey:0 type:P checksum:885ECCE2 plane_checksum:[7D89AD8E DC745BDC 0E23C369] mean:[158 128 128] stdev:[101.7 4.5 4.0


    



    Is there a way to obtain the system time when this frame was captured using FFMPEG ? Any inputs will help.

    


  • How to not add AdaptationSet for audio if audio stream is not present in input file

    13 juin 2019, par Saurabh

    I am using ffmpeg-dash to create mpd files. I am using following command to generate the same :

    ffmpeg -i input/video.mov \
    
        -map 0:v:0 -map 0:v:0 -map 0:v:0 -map 0:a\?:0 \
    
        -b:v:0 350k -c:v:0 libx264 -filter:v:0 "scale=320:-1" \
    
        -b:v:1 1000k -c:v:1 libx264 -filter:v:1 "scale=640:-1" \
    
        -b:v:2 3000k -c:v:2 libx264 -filter:v:2 "scale=1280:-1" \
    
        -use_timeline 1 -use_template 1 -window_size 6  -adaptation_sets "id=0,streams=v id=1,streams=a"  \
    
        -seg_duration 2 -threads 16 -hls_playlist true -f dash output/ffmpeg/output.mpd

    This works with video which has audio streams, but for the case there is no audio stream in the video file, I get empty entry for audio in mpd files like following, which is not valid and fails while playing in Exo Player in Android.

    <adaptationset contenttype="audio" segmentalignment="true" bitstreamswitching="true">
    
</adaptationset>

    I tried adding ? in option adaptation_sets like : id=0,streams=v id=1,streams=a?, however that also adds above line.

    One solution is to run different commands for different videos by first checking whether there is audio stream or not, but would be better if there is some option which add audio adaptationSet only if audio stream is present in the input file.

  • Evolution #4405 : activation du controleur traduction si le plugin crayon est présent

    27 novembre 2019

    Une question me vient : ça peut pas être fait en JS dans crayons, dans une forme de script à lancer en pre-exécution de crayons ? quitte à ajouter ici des attributs data-trad-molude=xxx par exemple plutôt, systématiquement ?

    Cela dit, comme discuté sur IRC, la révision https://zone.spip.net/trac/spip-zone/changeset/118766/spip-zone est un peu hasardeuse car ça ne prend pas en compte plusieurs choses :
    - 1) le fait que les fichiers de langues puissent ne pas être accessibles en écriture sur le disque
    - 2) qu’un module de langue peut être complété en suivant le path de SPIP, par exemple avec : "plugins/chats/lang/chats_fr.php" et "squelettes/lang/chats_fr.php" (qui en ajoute ou surcharge quelques uns)
