IP カメラからの RTSP ストリームを記録して再ストリーミングするアプリケーションに Live555 ストリーミング メディアを使用しています。そのために、録画には openRTSP を使用し、カメラ ストリームの再ストリーミングには live555 プロキシ サーバーを使用しています。いくつかのカメラでは、カメラの録画が正常に行われるという奇妙な問題に直面していますが、live555 プロキシ サーバーは同じカメラ ストリームに対して新しいストリームを生成できません (詳細な出力ダンプに失敗の兆候はありません。ただし、プロキシ サーバーによって生成された rtsp url は、rtsp クライアントによってデコードできません)。live555 プロキシ サーバーの詳細がわからないため、この問題に取り掛かることができませんでした。VLC を使用して同じカメラ ストリームをストリーミングしようとしたところ、問題なく動作しました。これで何が問題になる可能性がありますか。参照用に詳細出力を添付します。
