我尝试了以下操作，但没有效果。
ffmpeg -i rtmp://83.229.210.89/RAZTV/BTVraztv1 -map 0 -b:v 900k -vcodec libx264 -acodec aac -b:a 256k -strict -2 -t 3600 /media/TV_1T_3T_6/ffmpegtest/ort.mp4 -i rtmp://mirtv.cdnvideo.ru/mirtv-live/mirtv600.sdp -map 1 -b:v 900k -vcodec libx4 -acodec aac -b:a 256k -strict -2 -t 3600 /media/TV_1T_3T_6/ffmpegtest/mir.mp4 -i rtmp://chanson.cdnvideo.ru/chanson-live/shansontv.sdp -map 2 -b:v 900k -vcodec libx264 -acodec aac -b:a 256k -strict -2 -t 3600 /media/TV_1T_3T_6/ffmpegtest/shansontv.mp4 -i rtmp://83.229.210.89:1935/TROTV/BTVtro0 -map 3 -b:v 900k -vcodec libx264 -acodec aac -b:a 256k -strict -2 -t 3600 /media/TV_1T_3T_6/ffmpegtest/tro.mp4
看起来它挂在第二个流上，没有动静。SOS 请帮忙。我有 4 个流 URL。我希望它们同时一起录制。
使用一个 ffmpeg 命令：
- 我想：
rtmp://83.229.210.89/RAZTV/BTVraztv1 to record into file: /media/TV_1T_3T_6/ffmpegtest/ort.mp4 - 我想：
rtmp://mirtv.cdnvideo.ru/mirtv-live/mirtv600.sdp to record into file: /media/TV_1T_3T_6/ffmpegtest/mir.mp4 - 我想：
rtmp://chanson.cdnvideo.ru/chanson-live/shansontv.sdp to record into file: /media/TV_1T_3T_6/ffmpegtest/shansontv.mp4 - 我想：
rtmp://83.229.210.89:1935/TROTV/BTVtro0 to record into file: /media/TV_1T_3T_6/ffmpegtest/tro.mp4
我现在得到的日志是：

哇哦，我明白了问题所在！所以这是解决办法。在我的情况下，FFMPEG 挂在其中一个有问题的流上，因此无法继续开始录制列表中的其余流。基本上，使用 FFMPEG，您必须在单独的线程中为每个流执行命令。基本上，在您的 jar 中设置主方法来启动单独的线程，然后分别开始录制每个流。这样，如果 ffmpeg 无法连接到其中一个并挂起，它就不会中断其余流的录制。
