Hello Everyone, I am trying to seek my audio ogg file with the following:
int64_t targetPts = av_rescale_q(seekTimeMicro, AV_TIME_BASE_Q, streamTimeBase); av_seek_frame(avFormatContext, streamInfoIndex, targetPts, AVSEEK_FLAG_BACKWARD); This works all fine. Most of the time AVSEEK_FLAG_BACKWARD makes sure that the stream is seeked to a time before targetPts. However, there are times the opposite happens, seeking a time after targetPts. I can see this with the first frame I request from avcodec_receive_frame() having pts (avFrame->pts) greater than my targetPts. I need to ensure that the first frame I receive is always smaller than my targetPts. (it's an overhead in my system, long story). I read it that here <https://stackoverflow.com/questions/20734814/ffmpeg-av-seek-frame-with-avseek-flag-any-causes-grey-screen>: "It appears that, for some reason, av_seek_frame() using AVSEEK_FLAG_BACKWARD returns the next keyframe when the frame that I am seeking is the one directly before this keyframe. Otherwise it returns the previous keyframe (which is what I want).". I suspect that this is the case. However, this post is too old so it might be outdated. Could you help me? Thank you!
