motion ファイル名の拡張子

use_extpipe on

でpipeで外部エンコーダを利用するとon_movie_endイベントでファイル名をパラメータとして渡したときに、拡張子がついていたりついてなかったりする。

トリガー条件が不明。

ログ(/var/log/motion/motion.log)を見てみると event_newfile: でファイル名が出力されているので見てみると、extpipeを使い始めたタイミングで2回ファイル名が出力されているように見える。extpipeがonでも拡張子があったりなかったりする。

問題がなさそうな時

問題が発生している前後では拡張子がないファイルが作成されている感じになっている。

動作させてるバージョン。

解決策としてはイベント中の処理スクリプトで拡張子を付加して対応したが、少々気持ち悪い動作というか多分バグ。仕様としては拡張パイプを使用した場合の拡張子がついてしまっているのがおかしいかな。
