有时 ffmpeg 永远不会完成，从而阻止转换队列中的其他视频。是否可以在 ffmpeg 中设置某种超时，如果它没有在给定时间内完成，例如 5 分钟，它就会终止
我的命令今天看起来像这样：
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
更新。感谢 LordNeckBerd，您为我指明了正确的方向！
所以我现在看到它不是 ffmpeg 真正挂起的，问题是我从 linux 进程读取输入流的 java 代码将阻塞，因为 ffmpeg 永远不会返回行尾，我现在在运行命令时看到了这一点。这是阻塞线，它等待我的更多输入。

所以现在这里有两个问题。首先是为什么这个特定的转换失败了，其次，如何确保 ffmpeg 没有使这个（对于我的 Java 进程）阻塞命令要求更多输入。
