FFmpeg 时间戳问题
本帖最后由 learn_ffmpeg 于 2020-5-26 17:53 编辑最近的项目需要将不同的M3U8中的TS片动态的制作成一个M3U8列表，因为FFmpeg 目前只兼容连续递增的DTS时间戳，所以就改了HLS读取hls_read_packet()函数中的部分代码，对av_read_frame()读取出来的packet包从新打时间戳，
视频采用采用如下方式：DTS = DTS + av_rescale_q(1, fps, s->streams->time_base);
PTS = DTS - (pkt->dts - pkt->pts);上述方式计算出来之后和原视频的时间戳是一致的；
音频采用如下方式：// 以AAC为例
PTS += 1024 * s->streams->time_base.den / c->audio_sample_rate;
DTS = PTS;但是音频的时间戳算出来反而和源时间戳不一致，计算出来的值有差距，大神帮忙看下这么计算是有什么问题吗？谢谢
下面是部分日志，befor 为av_read_frame()读取出来的pkt的时间戳，after 为转换之后的时间戳： befor pts = 21096522, dts = 21096522 , filename = /opt/Film18/NVodUpload/电影/2020/5月/2020-5-11@12-28-32//player233.ts , avtype = 1

优化了下处理逻辑，通过ext-x-discontinuity 检测到有不连续的时间戳到来，然后只对这个时间戳衔接的部分自己计算时间戳，衔接好了之后再原有的时间戳基础上增加差值，达到时间戳连续的目的，目前测试没有问题，可以流畅的衔接！
但是上面为什么音频的时间戳计算有问题，还需要高人指点，谢谢 优化了下处理逻辑，通过ext-x-discontinuity 检测到有不连续的时间戳到来，然后只对这个时间戳衔接的部分自己计算时间戳，衔接好了之后再原有的时间戳基础上增加差值，达到时间戳连续的目的，目前测试没有问题，可以流畅的衔接！
