日々進化している BetaPlayer ・・・
このソフトを使うとハードウェアの性能を 100% 引き出すには、ソフトウェアのチューンナップが必要という事が良く分かります。
作者の方に感謝です。

BetaPlayer は、安定版と開発版があります。
開発版は、開発中のものでバグが含まれている可能性があります、ですがチューンナップも進んでいるのでパフォーマンスは高いです。
BetaPlayer の結果を見ていただければ分かると思いますが、安定版と開発版でパフォーマンスがだいぶ違います。

開発中の 0.090 以降で QVGA で 200% を超える良いスピードを出していますね。また 640x352 では ATI に最適化されている SigIII を上回る性能を発揮しました！

0.093 だと全てのファイルで三桁台になりました！今回のバージョンでは WirelessMMX ( PXA27x で搭載された SIMD ) に対応したようで急激にパフォーマンスが向上しております。HQ でもなんら問題ないですね。

BetaPlayer UNSTABLE 0.090

QVGA - VGA
BetaPlayer 0.04 ( 安定版 ) ではちょっと納得のいかない結果でしたので、開発中の UNSTABLE.0.090 で試してみます。

オプションは全て以下のようにしました。

Smooth Zoom (only 50%)
Dither
Video Driver => Raw FrameBuffer

BetaPlayer 0.04 よりは早くなって 640x352 1024Kbps だと 100% を超えました。
SigIII で同じファイルが 101.99% http://comwee.net/archives/000136.html ですから、ATI Imagion に最適化されている SigIII を超えています。
これで e830 + VGA に最適化されたらどうなるのでしょう？かなり早いのかも。

BetaPlayer 0.04

QVGA - VGA
BetaPlayer 0.04 ( 安定版 ) で試してみます。

オプションは全て以下のようにしました。

Smooth Zoom
Dither
Slow Video Memory
Video Driver => Raw FrameBuffer

QVGA

まずは QVGA でテストです。QVGA の動画を VGA で表示させる場合「QVGA => VGA 拡大」の処理があるので不利、との話があります。

フルスクリーンでもほぼ問題なく再生されました。でもたまに音声が遅れます。
こま落ちはあまり感じませんが、音声がずれたりスローになるので気味が悪いです。

VGA

次に VGA でテストです。

フルスクリーンで画像のこま落ちはあまり感じませんでしたが、音声がひどく遅れます。
きびしいなぁ。


上記のファイルをメインメモリにコピーして再生してみました。

のっけからダメです。数値的には SD と大差はありませんが、音と画像のずれもひどいですし、こま落ちが目立ちます。
