@winlinvip If this is the case, can you set the callback function to be processed logically by the business application

[yrJim]

@winlinvip 这个问题在播放flv时会出现，对同一个流用hls播放时不会出现，报错信息却提示是HLS解码失败，这是不是有问题

I also encountered this issue, and upon investigation, it appears that there is a problem with the parsing of NALU. The frame length information at the beginning of the IBMF format might start with 000001, which has been mistakenly identified as the ANNEXB format.

I have configured this on my end, and there are no more error messages.
