  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • rtpdec : fix issue with conversion from unsigned to signed

    rtpdec : fix issue with conversion from unsigned to signed

    When receiving an RTCP packet, the difference between the last RTCP
    
timestamp and the base timestamp may be negative. As these timestamps
    
are of the uint32_t type, the result becomes a large integer. Cast
    
the difference to int32_t to avoid this issue.
    

    The result of this issue is very large start times for RTSP
    
streams, and difficulty to restart correctly after a pause.

  • id3v2 : catch avio_read errors in check_tag

    11 mai 2015, par Andreas Cadhalpun
    id3v2 : catch avio_read errors in check_tag

    Since len is an unsigned int, the comparison is currently treated as
    
unsigned and thus ignores all errors from avio_read.
    

    Thus cast len to int, which is unproblematic, because at that point len
    
is between 0 and 4.
    

    This fixes ’Conditional jump or move depends on uninitialised value’
    
valgrind warnings in is_tag.

    I am using ffmpgeg to capture video from my desktop using
    ffmpeg -f v4l2 -s 320x240 -r 25 -i /dev/video0 -f alsa -ac 2 -i hw:0 http://localhost:8091/feed1.ffm/

    i am able to see this stream in chrome.
    but Firefox is showing message as MIME type not supported and not able to decode.
    but if I run the same webm video from static file it is playing in firefox
    but if I try to access via http://localhost:8091/live1.webm i am getting MIME type error,
    please let me know what additional settings need to be done in Firefox to play webm videos from my server address and port.
    Again I am reiterating that this is playing ok in chrome but not in Firefox.

    Please reply.

    hi all,

    i am able to play in firefox also after i changed audiocodecs to libvorbis and removing AudioChannels parameter from ffserver config file.

    thanks for your attention
