WebMay 1, 2015 · Yes that was conceptual, although I've seen people use "I" vs "i" to distinguish between IDR and non-IDR I-frames. And yes, setting keyinit to the desired gop size * 2 is a way to force all I frames inside the gop to be non-IDR I-frames. Then the ffmpeg -force-key-frames over-rides key-init in the x264opts. WebJun 15, 2011 · The duration of an MPEG audio frame is a function of the sampling rate and the number of samples per frame. The formula is: frameTimeMs = (1000/SamplingRate) * SamplesPerFrame In your case this would be frameTimeMs = (1000/44100) * 1152 Which yields ~26ms per frame. For a different sampling rate you would get a different duration.
