loreg 24485ea59f Esdots now finds random access points in H.264 streams. These are defined as : IDR pic OR I pic with SEI unit with recovery_point.
In choose_nal_type in esdotc.c there is a boolean value rec_point_required. It you set it to FALSE any I pic is considered a random access point.
The field recovery_frame_cnt is not used (as if it was 0). If it is != 0 a warning message is printed.
The fields broken_link_flag, exact_match_flag and changing_slice_group_idc are not considered (as 0).

In the final message the max, min and mean duration of a GOP are shown. For H.264 streams this is defined as the distance between 2 random access points. If no full GOP is found this info is not displayed.

The -gop switch works as before.

In esdots a function choose_nal_type has been added.
In nalunit.c a function read_SEI_recovery_point has been added.
The structure nal_SEI_recovery_data has been added, in order to cope with the recovery_point message. It's added to nal_innards too. See nalunit_defns.h
