解决方法:由于我们为这些未设置时间戳的输入帧填充有效时间戳不是一件很容易的事(需要结合输入视频是否采用B帧等),因此在输入输出帧率相同时,我们可以将这些携带无效时间戳的帧正常送至编码器编码并输出,而不是丢弃。 5. "dts < pcr" 在线CBR转码时常遇到"dts < pcr, TS is invalid"的打印,时间久了也可能引...
如下所示: cur_dts is invalid (this is harmless if it occurs once at the start per stream) cur_dts is invalid (this is harmless if it occurs once at th
pcr是节目时钟参考,pcr、dts、pts都是对同一个系统时钟的采样值,pcr是递增的,因此可以将其设置为dts值,音频数据不需要pcr。如果没有字段,ipad是可以播放的,但vlc无法播放。打包ts流时PAT和PMT表是没有adaptation field的,不够的长度直接补0xff即可。视频流和音频流都需要加adaptation field,通常加在一个帧的第一...
