The translation to English is: 'The error is:

The translation to English is:
'There was an error while parsing the sps, you may need to push the stream to my server, I need to debug it.

The problem reoccurred when using recorded flv for streaming, it is an issue with parsing sps.

The data is as follows:

(lldb) p nb_rbsp
(int) $0 = 55
(lldb) x/55xb rbsp
0x1010004c0: 0x64 0x00 0x29 0xad 0x00 0xce 0x50 0x1e
0x1010004c8: 0x00 0x89 0xf9 0x70 0x11 0x00 0x00 0x0e
0x1010004d0: 0x10 0x00 0x02 0xbf 0x20 0xe0 0x00 0x00
0x1010004d8: 0x02 0xfa 0xf0 0x80 0x00 0x01 0xdc 0xd6
0x1010004e0: 0x52 0x2f 0x7e 0x30 0x00 0x00 0x01 0x7d
0x1010004e8: 0x78 0x40 0x00 0x00 0xee 0x6b 0x29 0x17
0x1010004f0: 0xbf 0x06 0xd0 0x44 0x22 0x52 0xc0

Revise this analysis according to the h264 standard.

if( seq_scaling_matrix_present_flag )
    for(i=0;i<((chroma_format_idc != 3)?8:12);i++){
        seq_scaling_list_present_flag[ i ]
        if( seq_scaling_list_present_flag[ i ] )

The parameters are as follows:

(lldb) p/x seq_scaling_matrix_present_flag
(int8_t) $15 = 0x01
(lldb) p chroma_format_idc
(int32_t) $16 = 1

The parsed width and height are:

It seems to be 1920x1080, but let's not worry about it for now.
