DTS是个无效值。PTS的计算是根据ffmpeg的例子写的。 pkt.pts= av_rescale_q(oAcc->coded_frame->pts, oAcc->time_base, audio_st->time_base); 1. dts到底需不需要自己计算? 2. 还有播放速度过快的可能原因? 3. 还有PTS和DTS的具体含义? int64_t pts; ///< presentation time stamp in time_base ...
To calc the ptsav_rescale_qdoes: takes 2 time_base, multiplies their fractions in cross and then compute the pts. Why it does this in this way? As I debugged, theencodedPacket.ptshas value incremental by 1, so why changing it if it does has value? At the beginning the dts value i...

Generally the PTS and DTS will only differ when the stream we are playing has B frames in it. Q:关于b帧和时间戳的问题 我从mpeg2视频中用av_read_frame()读取视频帧并解码,顺序是IPBBPBB... 它们的pts顺序是1423756...现在我要把这个视频再用mpeg2编码,最大b帧数还是2.那么我在编码时是否要将...
Therefore I would expect there to be no problem if I intentionally created a video with a PTS value starting at, say, the current wall clock time. I want to send a live stream using ffmpeg, but embed the current time into the stream. This can be used both for latency calculation while...
关于“ffmpeg 命令行版本转换其他格式为m2ts会使视频流跟音频流的pts直接延迟1秒多?” 的推荐: 仅延迟mp4文件中音频流的一个通道 使用adelay过滤器: ffmpeg -i "test.mp4" -i "test.mp4" \ -filter_complex[1:a]adelay=0|2000[out] \ -map 0:v -c:v copy "test_delay.mp4" adelay采用以毫秒为单位...
