  • Taille des images et des logos définissables

    9 février 2011, par

    Dans beaucoup d’endroits du site, logos et images sont redimensionnées pour correspondre aux emplacements définis par les thèmes. L’ensemble des ces tailles pouvant changer d’un thème à un autre peuvent être définies directement dans le thème et éviter ainsi à l’utilisateur de devoir les configurer manuellement après avoir changé l’apparence de son site.
    Ces tailles d’images sont également disponibles dans la configuration spécifique de MediaSPIP Core. La taille maximale du logo du site en pixels, on permet (...)

  • FFMPEG generates an empty master playlist

    23 octobre 2019, par Сергей Барахтенко

    I use the following FFMPEG command to generate playlists and a master-playlist for later insertion into a player with HLS support :

    ffmpeg/ffmpeg.exe -i input/test.mp4 
    
-preset fast  
    
-g 150 
    
-sc_threshold 0 
    
-threads 4 
    
-map 0:v:0 -map 0:a:0 -map 0:v:0 -map 0:a:0 -map 0:v:0 -map 0:a:0 -map 0:v:0 -map 0:a:0 
    
-filter:v:0 scale=h=240:w=-2  -minrate:v:0 75k  -maxrate:v:0 218k  -bufsize:v:0 300k -b:v:0 150k  
    
-filter:v:1 scale=h=360:w=-2  -minrate:v:1 138k -maxrate:v:1 400k -bufsize:v:1 552k -b:v:1 276k 
    
-filter:v:2 scale=h=480:w=-2 -minrate:v:2 375k -maxrate:v:2 1088k -bufsize:v:2 1500k -b:v:2 750k 
    
-filter:v:3 scale=h=720:w=-2  -minrate:v:3 512k -maxrate:v:3 1485k -bufsize:v:3 2048k -b:v:3 1024k 
    
-var_stream_map "v:0,a:0 v:1,a:1 v:2,a:2 v:3,a:3" 
    
-master_pl_name master.m3u8 
    
-f hls -hls_time 6 -segment_time 6 -hls_list_size 0 -segment_format mpegts 
    
-hls_playlist_type vod -hls_segment_filename "output/conversion/K8eYn1X1/res-%v/segment-%d.ts"  output/conversion/K8eYn1X1/res-%v/playlist.m3u8

    Based on information from various sources, this command line should do the following :

    1. take a video stream from the input file,

    2. apply filters with different settings four times,

    3. combine it into one stream,

    4. cut into TS-fragments for 6 seconds,

    5. write information about each resolution to the playlist.m3u8,

    6. create a master-playlist and write information about upcoming playlists in it

    Everything works correctly, BUT : fragments are created, playlists are created, but the master file is empty

    If you play with the command line, more precisely, leave only one filter, then everything works fine : and fragments are cut and playlists are created and a master-playlist is also created

    Also, I noticed that if I watched the folder in which all the files are stored, I noticed one thing : when using the command given above, a 7kb file is created, and then in the same second, it seems to be cleared . Why is this happening, I do not understand

    Upon completion of processing in the log, the last line :

    [hls @ 000001ff73b87200] Opening 'output/conversion/K8eYn1X1/master.m3u8' for writing

    Maybe I’m doing something wrong ? Maybe the commands are in the wrong order ? Tell me, who knows ?

    Thanks
