HEVC: Picture split up in multiple NAL units -


during development work regarding hevc encountered camera streams pictures in multiple nal units. when analyzing bitstream noticed there 3 nal units per picture. noticed first_slice_segment_in_pic_flag = 1 first nal unit , first_slice_segment_in_pic_flag = 0 2 following nal units.

is there way of knowing how many nal units make full picture or nal unit final 1 of current picture without looking @ 4th nal unit (the first 1 of next picture)?

no not possible. know end of picture after decoding last ctu of picture or when first slice of next picture.

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
