i need map x.264 clip matroska container using ffmpeg:
ffmpeg -i f-0.mp4 -c copy f-0.mkv here ffmpeg console output:

delay relative video : 1mn 5s here mediainfo original f-0.mp4 file:
audio id : 2 format : ac-3 format/info : audio coding 3 mode extension : cm (complete main) format settings, endianness : big codec id : ac-3 duration : 2mn 8s bit rate mode : constant bit rate : 160 kbps channel(s) : 2 channels channel positions : front: l r sampling rate : 48.0 khz bit depth : 16 bits compression mode : lossy delay relative video : 67ms stream size : 2.44 mib (3%) mediainfo f-0.mkv output:

i concerned information (delay relative video) used players or other applications delay should corrected. there way prevent happening?
adding ffprobe output: f-0.mp4 clip
