atrunさんからのお手紙

録画時のoutputが、メールで届いていた。
うー。リングバッファあふれのwarningが大量に。30秒くらいだとともかく、３時間録るとけっこうあるのね。
そういえばtsselectかけてなかった。

こんな大量にPIDがあるのね。おそらく一番多いpid=0x0111がVideoじゃないかと予想して、dropは242/97000673だから0.025%くらい。観たときどれくらい気になるんだろうか。pid=0x1fc8は21099個しかないけど、こんなもん？
１本でこれだと、２同時録画だともっと悪化しそう。がんばれAtom。＜無理です
読み込み処理をugenからカーネルモジュールに変えてみるのも考えた。読み込み後の処理(Multi2復号とファイル出力)が遅くて、TS結果を書き出すリングバッファがあふれちゃってるわけで、b25はuser側でやるしかないから改善しないよなあ。b25に手を入れたくないし。むう。
