  • L’utiliser, en parler, le critiquer

    10 avril 2011

    La première attitude à adopter est d’en parler, soit directement avec les personnes impliquées dans son développement, soit autour de vous pour convaincre de nouvelles personnes à l’utiliser.
    Plus la communauté sera nombreuse et plus les évolutions seront rapides ...
    Une liste de discussion est disponible pour tout échange entre utilisateurs.

  • movenc : Allow interleaving samples when writing fragmented files

    movenc : Allow interleaving samples when writing fragmented files

    This is incompatible with the omit_tfhd_offset flag (writing
    
position independent fragments with interleaving requires the
    
default_base_moof flag).
    

    This makes the moof atoms slightly bigger, but can be better for
    
playback (improving locality of sample data in the mdat).

  • rtpenc : Don’t set max_frames_per_packet based on the packet frame size or frame rate

    25 février 2015, par Martin Storsjö
    rtpenc : Don’t set max_frames_per_packet based on the packet frame size or frame rate

    Instead check the timestamps while muxing, to avoid buffering a
    
too long timestamp range into one single packet.
    

    This makes the AMR and AAC packetization slightly less efficient,
    
since we set a possibly unnecessarily high max_frames_per_packet.
    
(These packetizers end up doing a memmove of the TOC bytes if
    
sending a packet before max_frames_per_packet is achieved, and
    
we end up setting max_frames_per_packet to a value that should
    
be high enough for most uses.)
    

    All packetizers that use max_frames_per_packet now set it either
    
to a default value, or to a value calculated based on other
    
parameters, so none of them rely on the previous default setting.
    

    For iLBC, copy one frame at a time, to allow checking the timestamp
    
range for each of them - basically doing potentially multiple
    
loops to simplify the code instead of trying to calculate the
    
number of frames to buffer while honoring s1->max_delay.
    

    This is in preparation for reducing the coupling between libavformat
    
and libavcodec, by not having the muxers use the encoder field
    
frame_size (which may not be available during e.g. stream copy).

  • vulkan_ffv1 : shortcut +-1 coeffs in symbol reading

    vulkan_ffv1 : shortcut +-1 coeffs in symbol reading

    Slightly faster, and allows for further optimizations.
