1. -2的作用与-1类似,也是用于自动计算另一个尺寸,同时保持宽高比。但-2的特殊之处在于,它会确保计算出的宽度或高度是偶数,这是为了满足某些视频编码器的要求,它们需要偶数的分辨率尺寸。这对于编码像H.264这样的视频时特别重要,因为(如前所述)这些编码器使用基于块的编码算法,其要求块的尺寸(通常是16×16像素...

The problem with your fix is that it changes dimensions in the code that define how ffmpeg should interpret data that is sent from the python code without changing what data is sent. If the image has an odd width and you reduce that width by one, then each line of the image has a le...
Given a range (which is 1 to 1000) and we have print all numbers which are divisible bye 7 and not divisible by 5 in Python. Sample Input/Output Input: Given input range is 1 to 1000 Output: 7, 14, 21, 28, 42, 49, 56, ... ...
Leap year program in Python: Here, we will learn how to check a given year is a leap year or not in Python programming language?ByBipin KumarLast updated : April 09, 2023 Aleap yearis a year that is completely divisible by 4 except the century year (a year that ended with 00). A...
raise SystemExit( 'Number of points must be divisible by batch size' ) # Newline delimit the data for batch in range(0, len(data), batch_size): time.sleep(10) current_batch = '\n'.join( data[batch:batch + batch_size] )
When you look at the image width/height, the values are usually divisible by 8. We know that 8 bits = 1 byte and certain processing algorithms work more efficiently if the size in question is a multiple of 8 (or 16, 32, 64, etc). Indeed, that could be it. Well spotted. In the...
We need to adjust value of when is fully divisible by 7. I think use of while...loop is preferable in this case. We're not supposed to alter a for...loop counter, we use while...loop when we need to. lst=[ 3, 21, 5, 6, 14, 8, 14, 3 ] n = len( lst ) #expected...
this. The children sit in a circle and count up from one; but, if your number is divisible by 3 you say “Fizz” instead of your number and if your number is divisible by 5 you say “Buzz” instead of your number. If your number is divisible by both 3 and 5 you say “Fizz ...
