[FFmpeg-user] An error in decoding RTMP (h264&aac) live streaming

[xyzero]

Dear Sir / Madam:
    I use ffplay to play a RTMP live streaming (url is "rtmp://live.hkstv.hk.lxdns.com/live/hks").
    After 16819 seconds of receiving, the decoding function returns error, and the error info is as follows.
    Or it can be easily happened when use "$ ffmpeg -ss 16750 -i rtmp://live.hkstv.hk.lxdns.com/live/hks -f null - "command.
    I tried ffmpeg version 3.0, 3.1, 3.3, and it has the same problem. I hope you can tell me where is wrong or how to slove this problem.
    Best wishes,
    xyzero

[flv @ 08772fe0] Audio codec (e) is not implemented. Update your FFmpeg version
to the newest one from Git. If the problem still occurs, it means that your file
 has a feature which has not been implemented.
