2111a191eb Check index in mjpeg AC decode against overflowing. 
This fixes a possibly exploitable buffer overflow and it will likely also be needed for future overreading fixes.

fc068f9f27 Fixed DXVA_Slice_H264_Long::BitOffsetToSliceData value. 
The 8 bits offset (nal unit type) should not be added, as the spec says:

"This bit offset is the offset within the RBSP data for the slice, relative
to the starting position of the slice_header() in the RBSP"

This fixes DXVA2 support for intel GPU.

4ad08021e8 Add a -force_key_frames option to ffmpeg. 
The option is useful to ensure that there is a seek point exactly at a
place the user will probably want to jump precisely sometime, the
major example would be the end of an opening and the beginning of a
chapter. The scene change detection system will often make it happen,
but not always for example if there is a fade-in.

See the thread:

946df0598b rtpdec: Return AVERROR(EAGAIN) for mpegts parsing errors 
This indicates that there was no error that needs to be reported to the
caller, so we can move on to parse the next packet immediately, if
available. The only error code that ff_mpegts_parse_packet can return
indicates that there was no packet to return from the provided data, for
which it returns -1.
