不知怎的，我发布了Azure Media Services，除了这些设置有大量的帧丢失（几乎每一帧）：
ffmpeg -i "http://stream01/hls/live/playlist-mid.m3u8" -strict -2 -c:a aac -b:a 192k
-ar 44100 -r 25 -g 60 -keyint_min 60 -b:v 2000k -c:v libx264 -bufsize 2000k
-maxrate 2000k -f flv "rtmp://publishurl.working.is/mystream1"
+我无法播放Azure中的网址。
当我发布到本地nginx-rtmp服务器时，帧丢失仍然存在，尽管我可以播放它。所以，我认为帧丢弃与ffmpeg无关，而不是Azure。处理器没有过载，可用带宽非常好。
当我尝试URL的original设置（位于最底部）时，我会另外发现这个ffmpeg错误Past duration 0.719994 too large
此处还有输出内容：
c:\ffmpeg\bin>ffmpeg -i "http://stream01/hls/live/playlist-mid.m3u8" -strict -2 -c:a aac -b:a 192k -ar 44100 -r 25 -g 60 -keyint_min 60 -b:v 2000k -c:
