The parameter for this depends on the output video codec.Īn ffmpeg command line for MPEG-2 TS can look like this:įfmpeg -i inputfile -vcodec mpeg2video -pix_fmt yuv422p -qscale 1 -qmin 1 -intra outputfile To allow frame-exact splitting on problematic input files the easiest way is to blow them up to consist only of I-frames. As the segmenter only supports transport stream only MPEG-2 TS and MPEG-4 TS do make sense. When using the Apple segmenter the only safe way to split files is to convert into an intermediate format which allows frame-exact splitting. missing audio+video between otherwise audio-synchronous consecutive segments.missing video frames at the start of each segment.asynchronous audio in some or all segments.Wether you split the file using ffmpeg or the Apple segmenter tool you often end up with The problem lies with frame exact splitting of arbitrary video input material.
When preparing videos for Apples HTTP streaming for iPad/iPhone you need to split your video into 10s chunks and provide a play list for Quicktime to process.
