[Libav-user] muxing.c example with dash format

[salsaman]

You may need something like:

  /* Some formats want stream headers to be separate. */
  if (oc->oformat->flags & AVFMT_GLOBALHEADER)
    c->flags |= AV_CODEC_FLAG_GLOBAL_HEADER;

where oc is your AvFormatContext * and c is your AvCodecContext.
