I'm trying to use the frame->pts value but I don't understand how to calculate the absolute time in milliseconds. Adding some logs I've found that: frame->time_base=1/48000 frame->sample_rate=16000 Using `1000 * frame->pts * frame->time_base` returns wrong results. The only way to get the correct value seems `1000 * frame->pts / frame->sample_rate` -- /Vittorio Palmisano/ _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
