How to divide my video horizontally using ffmpeg (without any other side-effects) ?
1er février 2021, par Mayank ThapliyalI am processing my video(640 X 1280 dimensions). I want to divide my video horizontally into 2 separate videos(each video will now be 640 X 640 in dimensions),then combine them horizontally (video dimension will be now 1280 X 640)in a single video. I did the research on the internet and my issue was solved and not solved at the same time


I made a batch file and add these commands in it :-


ffmpeg -i input.mp4 -filter_complex "[0]crop=iw:ih/2:0:0[top];[0]crop=iw:ih/2:0:oh[bottom]" -map "[top]" top.mp4 -map "[bottom]" bottom.mp4
ffmpeg -i top.mp4 -i bottom.mp4 -filter_complex hstack output.mp4



Yes,my task got solved but many other issues also came out of it :-


1.) My output video has NO audio in it. No idea why there is no audio in the end results


2.) My main video file (on which I am doing all this) is 258 MB in size. But the result was only 38 MB in size. No idea what is happening ? And even worse,I closely looked at the video,results were pretty same (only animation were not as smooth in output file as compared to input file)


3.) It is taking too much time(I know that computing takes some time but maybe there may be some way/sacrifice to make the process much quicker)


Thanks in advance for helping me

Revert "Don’t use expressions with side effects in macro parameters"
1er août 2016, par Martin StorsjöRevert "Don’t use expressions with side effects in macro parameters"
This reverts commit 25bacd0a0c32ae682e6f411b1ac9020aeaabca72.
Since 230b1c070, the bytewise AV_W*() macros only expand their
argument once, so revert to the more readable version of these.Signed-off-by : Martin Storsjö <martin@martin.st>
