【中文标题】如何使用 FFMPEG 保存 rtsp 流而不丢包【英文标题】：How to save rtsp stream without packet loss by using FFMPEG 【发布时间】：2016-11-18 06:33:22 【问题描述】：我正在使用 FFMPEG 保存实时摄像机流。当我尝试保存视频时，一些数据包丢失，因此视频无法正常播放。我正在使用以下 FFMPEG Library
我发送的命令是-
String[] cmd = "-y", "-i", "rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov", "-c:v", "libx264", "-acodec", "aac","-t", time, file_path;
execFFmpegBinary(cmd);
我也在尝试这个命令，但结果是一样的
String[] cmd = "-y", "-rtsp_transport", "tcp", "-i", "rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov", "-c:v", "libx264", "-preset", "slow", "-b:v", "500k", "-maxrate", "500k", "-bufsize", "3000k", "-vf", "scale=-1:480", "-threads", "0", "-codec:a", "libfdk_aac", "-b:a", "128k", "-t", time, file_path;
这里是命令输出的日志-

如何保存高质量的rtsp流而不丢包？任何帮助将不胜感激。
【问题讨论】：
在您使用 android 之前，是否有一些 ffmpeg 构建可以在测试流上运行而不会丢失？ IMO 您对作为 ffmpeg 的狭窄子集的 lib 构建有疑问。是否有更广泛的 mpeg 实现处理相同的流？ 尝试在 ffmpeg 命令中提高帧率 @RobertRowntree 我正在提高帧速率，但问题是一样的。实际上，当我通过虚拟 url 并保存 2 分钟或 5 分钟的视频时，它会保存 2 分钟或 5 分钟的视频长度但是当我在某处播放此视频时，它会冻结并再次继续。但是当我浏览我的应用程序实时网址并保存视频时，视频会像这样跳过（例如 22 秒到 35 秒，40 秒到 55 秒） . 来自 rtsp 模块的大量“最大延迟”消息。也许这意味着您需要一个更快的多核 CPU，它可以消耗所有这些帧而不会落后。将您的 ffmpeg 安装在更快的盒子上并运行相同的表达式，看看它是否消耗相同的输入而没有所有的数据包丢失/丢包.. android 上的 ffmpeg 由于其限制而速度较慢......电池，小型设备。好的 linux 机器上的帧速率容量将是你在 android 上的 10 倍。 我们将-reorder_queue_size 设置为4000，将-max_delay 设置为10000000，这减少了丢失数据包的数量，但并没有完全解决问题。我们为我们正在做的演示/演示而构建了这个，只需要说“足够好！”™。
【参考方案1】：
如何保存高质量的rtsp流而不丢包？
不要重新编码。按原样保存。
ffmpeg -y -i "$source" -c copy -t "$time" "$filepath"

【参考方案2】：我遇到了完全相同的问题，但我终于找到了解决方案：
只需在-i 选项之前添加-rtsp_transport tcp，而不是之后！
这个命令对我有用：
./ffmpeg_g -rtsp_transport tcp -i rtsp://192.168.5.163:554/live/av0 -c copy /root/test.ts
【讨论】：
呃，使用-rtsp_transport tcp 会让事情变得更糟。当然，它减少了拖影，但它会错过很多帧，跳过整秒的视频。
如果有人只想从实时流中捕获 1 帧，这非常有效！无丢包：ffmpeg -y -rtsp_transport tcp -i rtsp://<username>:<password>@<ip_address>/live[/<path>] -frames:v 1 test.jpg
-rtsp_transport tcp 也为我解决了这个问题。 TCP 和 UDP 之间的主要区别在于 TCP 会为收到的数据包发送收据，因此不会丢失数据包（流量控制）。 UDP 如果您只是实时观看视频流并且不会为一些冻结而烦恼，那就更好了。如果您正在下载流然后使用-rtsp_transport tcp，这将确保没有数据包丢失【参考方案3】：
您必须在输入命令之前移动传输/tcp，使其看起来像这样：
ffmpeg -rtsp_transport tcp -i $source -acodec copy -vcodec copy $output
