None of the files have negative CTS or DTS, but the processing of the edit lists do lead to negative presentation times from some audio samples. Author misterkbar commented Jul 25, 2015 There was some questions as to why the audio got in this state. These were previously-generated A/V...

int32_tcts=(avio_rb24(s->pb)+0xff800000)^0xff800000;pts=dts+cts; 总结一下: 1. flv文件中Timestamp和TimestampExtended拼出来的是dts。也就是解码时间。 Timestamp和TimestampExtended拼出来dts单位为ms。 2. CompositionTime 表示PTS相对于DTS的偏移值, 在每个视频tag的第14~16字节, 。
