Comment (by jyavenard):

 Thank you for the quick fix.

 So by default, the old behavior is back.

 {{{
 @@ -844,7 +846,7 @@ end:
          avio_seek(pb, flv->datasize_offset, SEEK_SET);
          put_amf_double(pb, flv->datasize);
      }
 -    if (pb->seekable) {
 +    if (!(flv->flags & FLV_NO_DURATION_FILESIZE)) {
          /* update information */
  }}}

 why not use if (write_duration_filesize) ?
