Support FFmpeg timecode, fix AMF0 parsing failed. v5.0.179 v6.0.77 (#3804)

Browse source 
Please see https://github.com/ossrs/srs/issues/3803 for detail:

1. When using FFmpeg with the `-map 0` option, there may be a 4-byte
timecode in the AMF0 Data.
2. SRS should be able to handle this packet without causing a parsing
error, as it's generally expected to be an AMF0 string, not a 4-byte
timecode.
3. Disregard the timecode since SRS doesn't utilize it.

See [Error submitting a packet to the muxer: Broken pipe, Error muxing a
packet](https://trac.ffmpeg.org/ticket/10565)
