You could try this patch:
diff -r b2f67e83cf04 util/scan/scan.c

if (s->video_pid == 0)
s->video_pid = elementary_pid;
I'm a bit reluctant to commit this, though, as mpeg2 decoders
might have problems when fed with H.264 ;-/. A more complete
patch would add a command line parameter to output H.264
video pids.
In case 0x10 is not the correct stream type value, the video
pid should be listed as OTHER if you run "scan -vv". 0x10 is
listed in ISO-13181-1 for "ISO/IEC 14496-2 Visual".
Please report which type is actually used for H.264 in France.
