  • libavcodec/vaapi_decode : fix the problem that init_pool_size nb_surface

    libavcodec/vaapi_decode : fix the problem that init_pool_size < nb_surface

    For vaapi if the init_pool_size is not zero, the pool size is fixed.
    
This means max surfaces is init_pool_size, but when mapping vaapi
    
frame to qsv frame, the init_pool_size < nb_surface. The cause is that
    
vaapi_decode_make_config() config the init_pool_size and it is called
    
twice. The first time is to init frame_context and the second time is to
    
init codec. On the second time the init_pool_size is changed to original
    
value so the init_pool_size is lower than the reall size because
    
pool_size used to initialize frame_context need to plus thread_count and
    
3 (guarantee 4 base work surfaces). Now add code to make sure
    
init_pool_size is only set once. Now the following commandline works :
    

    ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 \

    - hwaccel_output_format vaapi -i input.264 \

    - vf "hwmap=derive_device=qsv,format=qsv" \

    - c:v h264_qsv output.264

  • hwframe : Allow hwaccel frame allocators to align surface sizes

    22 juin 2017, par Anton Khirnov
    hwframe : Allow hwaccel frame allocators to align surface sizes

    Hardware accelerated decoding generally uses AVHWFramesContext for pool
    
allocation of hardware surfaces. These are setup to allocate surfaces
    
aligned to hardware and hwaccel API requirements. Due to the
    
architecture, av_hwframe_get_buffer() will return AVFrames with
    
the dimensions set to the aligned sizes.
    

    This causes some decoders (like hevc) return these aligned size as
    
final frame size, instead of cropping them to the video's actual
    
dimensions. To make sure this doesn't happen, crop the frame to the
    
size the decoder expects when ff_get_buffer() is called.

  • Revision 86428 : Un autre type de jointure qui devrait fonctionner : cas simple : ...

    3 décembre 2014, par kent1@… — Log

    Un autre type de jointure qui devrait fonctionner :
    cas simple : $cle_depart dans la table_liee
    Ce cas pourrait exister par exemple si on activait une jointure de recherche sur les articles avec la table spip_evenements du plugin agenda.
    Il suffirait d’ajouter la ligne suivante dans le pipeline "declarer_tables_objets_sql" dans le fichier base/agenda_evenements :
    $tablesspip_articles ?rechercher_jointures ?evenement ? = array(’titre’ => 8, ’descriptif’ => 5, ’lieu’ => 5, ’adresse’ => 3) ;
