    Le lecteur ne fonctionne pas sur Internet Explorer
    Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.
    Si dans la configuration de ce module Apache vous avez une ligne qui ressemble à la suivante, essayez de la supprimer ou de la commenter pour voir si le lecteur fonctionne correctement : /** * GeSHi (C) 2004 - 2007 Nigel McNie, (...)

  • avformat/mpegtsenc : Fix mpegts_write_pes() for private_stream_2 and other types

    25 avril 2021, par zheng qian
    avformat/mpegtsenc : Fix mpegts_write_pes() for private_stream_2 and other types

    According to the PES packet definition defined in Table 2-17 of ISO_IEC_13818-1
    
specification, some fields like PTS/DTS or pes_extension could only appears if
    
the stream_id meets the condition :
    

    if (stream_id != 0xBC &&  // program_stream_map
    
    stream_id != 0xBE &&  // padding_stream
    
    stream_id != 0xBF &&  // private_stream_2
    
    stream_id != 0xF0 &&  // ECM
    
    stream_id != 0xF1 &&  // EMM
    
    stream_id != 0xFF &&  // program_stream_directory
    
    stream_id != 0xF2 &&  // DSMCC_stream
    
    stream_id != 0xF8)    // ITU-T Rec. H.222.1 type E stream
    

    And the following stream_id types don't have fields like PTS/DTS :
    

    else if ( stream_id == program_stream_map
    
|| stream_id == private_stream_2
    
|| stream_id == ECM
    
|| stream_id == EMM
    
|| stream_id == program_stream_directory
    
|| stream_id == DSMCC_stream
    
|| stream_id == ITU-T Rec. H.222.1 type E stream ) 
    
    for (i = 0 ; i < PES_packet_length ; i++) 
    
        PES_packet_data_byte
    
    
    

    

    Current implementation skipped the check of stream_id causing some kind of
    
streams like private_stream_2 to be incorrectly written with actually a
    
private_stream_1-like PES header with PTS/DTS field. For example, Japan DTV
    
transmits news and alerts through ARIB superimpose that utilizes
    
private_stream_2 still could not be remuxed correctly for now.
    

    This patch set fixes the remuxing for private_stream_2 and
    
other stream_id types.
