• avio : Allow custom IO users to get labels for the output bytestream

  4 mai 2016, par Martin Storsjö

  avio : Allow custom IO users to get labels for the output bytestream
  This allows callers with avio write callbacks to get the bytestream
  
  positions that correspond to keyframes, suitable for live streaming.
  In the simplest form, a caller could expect that a header is written
  
  to the bytestream during the avformat_write_header, and the data
  
  output to the avio context during e.g. av_write_frame corresponds
  
  exactly to the current packet passed in.
  When combined with av_interleaved_write_frame, and with muxers that
  
  do buffering (most muxers that do some sort of fragmenting or
  
  clustering), the mapping from input data to bytestream positions
  
  is nontrivial.
  This allows callers to get directly information about what part
  
  of the bytestream is what, without having to resort to assumptions
  
  about the muxer behaviour.
  One keyframe/fragment/block can still be split into multiple (if
  
  they are larger than the aviocontext buffer), which would call
  
  the callback with e.g. AVIO_DATA_MARKER_SYNC_POINT, followed by
  
  AVIO_DATA_MARKER_UNKNOWN for the second time it is called with
  
  the following data.

• Errors in compiling FFmpeg for windows10/aarch64 using Microsoft Visual Studio 2017 Preview edition

  29 octobre 2018, par Narsinga

  I am trying to compile FFmpeg (the Chromium version) for Windows10/Aarch64 configuration using Microsoft Visual Studio 2017 Preview community edition. I am running into errors in the assembly files as copied below (highlighted few errors). I believe FFmpeg is working for Linux/Aarch64 configuration (probably using GNU assembler) already in which case the same assembly code should also work for Microsoft ARM Macro Assembler as well. Please let me know if I am missing anything here and any pointers to help resolve the errors.
