問題があり、今日はそれを修正する方法や、どこから始めればよいかさえわかりません。
msx264 プラグインを使用する Linphone アプリケーションがあります。
OSxで実行するすべてのものと、からインストールされたffmpegバージョンport、ポートにselfupdateを使用しませんでした
bash-3.2# port installed ffmpeg-devel
The following ports are currently installed:
ffmpeg-devel @20130205_0+gpl2
ffmpeg-devel @20130328_0 (active)
ffmpeg-devel @20130328_0+gpl2
それで、msx264をコンパイルしてビルドしましたが、エラーはありませんでした。
今、私は CIP 解像度の VGA (640x480) でビデオを送信しようとしましたが、8 ～ 9 秒の大きな遅延が発生し、大きな遅延で表示されるセルフビューでさえも発生しました。
CIF (352x288) を構成すると、すべて問題ないように見えます。
セルフビューカメラの遅延が 4 ～ 5 秒あるのは本当に奇妙です。
セッション中のログから、msx264 プラグインが 97% の CPU を使用していることがわかりました。
PC (windows 7) では同じコードが正常に動作し、HD でも問題はありません。
問題は何ですか？
