这个是 redlive.xiaohongshu.com 暴露出来的直播链接。使用 h265 而不是默认 .flv 的 h264，码率也更高
https://live-source-play-hw.xhscdn.com/live/569992765504845111_orig.flv


ttmpdump直接输出的flv，ffplay能播放，但是VLC不识别flv中的HEVC编码，需要之后转码
rtmpdump -r "rtmp://live.xhscdn.com/live/569971301260745429" -o output.flv --live

让ffmpeg转码，VLC可以播放
ffmpeg -hide_banner -fflags +genpts -probesize 100M -analyzeduration 100M -i output.flv -c copy out.mkv
ffmpeg -fflags +genpts+igndts+discardcorrupt -err_detect ignore_err -avoid_negative_ts make_zero -i "input.flv" -c copy -map 0 out_fixed.mkv

查看单独packet
ffprobe -hide_banner -show_packets -select_streams v -print_format json yourfile.flv > file1.json
