  • Support de tous types de médias

    10 April 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...); audio (MP3, Ogg, Wav et autres...); vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...); contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google (...)

  • Supporting all media types

    13 April 2011, by

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats: images: png, gif, jpg, bmp and more audio: MP3, Ogg, Wav and more video: AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data: OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • ffmpeg: zoom a horizontal photo in a vertical video, fill the empty space at the top and bottom with a blurry photo

    23 October 2023, by Eugene Khyst

    I'm using ffmpeg to create a vertical video of zoomming a horizontal (landscape) photo.

    


    I want the photo to fit the width of the video, so the top and bottom of the photo need to fill the empty space with the blurry photo:

  • aarch64: vp9itxfm: Skip empty slices in the first pass of idct_idct 16x16 and 32x32

    9 January 2017, by Martin Storsjö
    aarch64: vp9itxfm: Skip empty slices in the first pass of idct_idct 16x16 and 32x32

    This work is sponsored by, and copyright, Google.
    

    Previously all subpartitions except the eob=1 (DC) case ran with
    
the same runtime:
    

    vp9_inv_dct_dct_16x16_sub16_add_neon:   1373.2
    
vp9_inv_dct_dct_32x32_sub32_add_neon:   8089.0
    

    By skipping individual 8x16 or 8x32 pixel slices in the first pass,
    
we reduce the runtime of these functions like this:
    

    vp9_inv_dct_dct_16x16_sub1_add_neon:     235.3
    
vp9_inv_dct_dct_16x16_sub2_add_neon:    1036.7
    
vp9_inv_dct_dct_16x16_sub4_add_neon:    1036.7
    
vp9_inv_dct_dct_16x16_sub8_add_neon:    1036.7
    
vp9_inv_dct_dct_16x16_sub12_add_neon:   1372.1
    
vp9_inv_dct_dct_16x16_sub16_add_neon:   1372.1
    
vp9_inv_dct_dct_32x32_sub1_add_neon:     555.1
    
vp9_inv_dct_dct_32x32_sub2_add_neon:    5190.2
    
vp9_inv_dct_dct_32x32_sub4_add_neon:    5180.0
    
vp9_inv_dct_dct_32x32_sub8_add_neon:    5183.1
    
vp9_inv_dct_dct_32x32_sub12_add_neon:   6161.5
    
vp9_inv_dct_dct_32x32_sub16_add_neon:   6155.5
    
vp9_inv_dct_dct_32x32_sub20_add_neon:   7136.3
    
vp9_inv_dct_dct_32x32_sub24_add_neon:   7128.4
    
vp9_inv_dct_dct_32x32_sub28_add_neon:   8098.9
    
vp9_inv_dct_dct_32x32_sub32_add_neon:   8098.8
    

    I.e. in general a very minor overhead for the full subpartition case due
    
to the additional cmps, but a significant speedup for the cases when we
    
only need to process a small part of the actual input data.
    

    This is cherrypicked from libav commits
    
cad42fadcd2c2ae1b3676bb398844a1f521a2d7b and
    
a0c443a3980dc22eb02b067ac4cb9ffa2f9b04d2.
