I have a list of mp4 files which are of kb's or of at max 4 MB (they were actually gifs but downloaded as mp4).So when I concatenate them using a list of them the video don't work as all of them are of different sizes (resolution wise ) and all of not are in vertical order.So any help with that matter and also I f someone would be kind enough to tell me the FFmpeg command to convert this mp4 list to gif 's without losing quality.Thanks in advance
I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
