ffmpeg が完了しない場合があり、その結果、キュー内の他のビデオの変換が妨げられます。所定の時間内に終了しない場合に終了するように、ffmpeg である種のタイムアウトを設定することは可能ですか (例: 5 分)
今日の私のコマンドは次のようになります。
ffmpeg -i /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141 -y -r 24 -ar 22050 -f mov -vf [in]transpose=1[rt0],[rt0]scale=iw*480/ih:480[sc0],[sc0]pad=640:480:140[pd0],movie=/srv/bsafe/tomcat7/webapps/ROOT/resources/images/logo_watermark.png [wm],[pd0][wm] overlay=W-w-140:0[out] /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141.mov -ar 22050 -b 1500k -vcodec libtheora -acodec libvorbis -f ogg -vf [in]transpose=1[rt0],[rt0]scale=iw*480/ih:480[sc0],[sc0]pad=640:480:140[pd0],movie=/srv/bsafe/tomcat7/webapps/ROOT/resources/images/logo_watermark.png [wm],[pd0][wm] overlay=W-w-140:0[out] /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141.ogg -ar 22050 -vcodec libx264 -profile baseline -vf [in]transpose=1[rt0],[rt0]scale=iw*480/ih:480[sc0],[sc0]pad=640:480:140[pd0],movie=/srv/bsafe/tomcat7/webapps/ROOT/resources/images/logo_watermark.png [wm],[pd0][wm] overlay=W-w-140:0[out] /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141_mp4.mp4
アップデート。ありがとうLordNeckBerd、あなたは私を正しい方向に向けました！
そのため、ffmpeg が実際にハングしていないことがわかりました。問題は、Linux プロセスから入力ストリームを読み取る Java コードがブロックされることです。これは、ffmpeg が行末を返さないためです。これは、コマンドを実行したときに表示されます。これはブロック線です。私からのさらなる入力を待ちます。

だから今ここにその2つの問題があります。1 つ目は、この特定の変換が失敗する理由です。2 つ目は、ffmpeg がこれを (私の Java プロセスに対して) ブロックするコマンドを作成していないことを確認し、さらに入力を要求する方法です。
