MKV-SEEKHEAD-PRESENT

Name

SeekHead presence.

Note

This is covered as a policy check and not an implementation check.

Reproducibility

ffmpeg -f lavfi -i testsrc2=s=120x80 -f lavfi -i sine -c:a flac -ar 8000 -vframes 2 -c:v ffv1 -level 3 -c:a flac -g 1 -y MKV-SEEKHEAD-PRESENT.mkv
sfk replace MKV-SEEKHEAD-PRESENT.mkv -bin '/114D9B74/EC8100EC/' -yes

Reproducibility Note

The sfk call intends to replace the 4 byte Element ID of the SeekHead Element with a 3 byte Void Element and a 1 byte Element ID of a Void Element (the Element Data Size and Element Data of the SeekHead is then converted into the Element Data Size of Element Data of a Void Element).
