8 juillet 2017, par JeffinI am trying to acheive the following effect using ffmpeg
I have tried multiple options , but failed so far,
I have referred the following questions , not happening for me
- FFmpeg : Add alpha channel to a video using a PNG mask
- FFMPEG Crop with side by side merge
- https://superuser.com/questions/916431/ffmpeg-filter-to-boxblur-and-greyscale-a-video-using-alpha-mask?rq=1
I have three videos but i have somewhat acheived the diagonal split for two videos using the following code , but still couldnt get the output for three videos or four
ffmpeg -i input0 -i input1 -filter_complex \
"[1:v][0:v]blend=all_expr=if(gt(X\,Y*(W/H))\,A\,B)" output -
FFmpeg - Rotating at angle
23 septembre 2017, par connorI’ve been working through FFmpeg, but I have been unable to get a rotation to run from the examples they have on their site. I am trying to "wiggle" a video back and forth at a fixed point on the bottom - think a head moving left to right (and so on).
I am attempting to do this with the filter "rotate" (https://ffmpeg.org/ffmpeg-filters.html#rotate). Attempting to use their examples, I get an error.
This is what I have so far :
ffmpeg -i vid1.mp4 -i vid2.mov -loop 1 -i image.png -filter_complex "\
[2:v]alphaextract, scale=240x160[mask];\
[0:v] scale=240x160, rotate=A*sin(2*PI/T*t) [ascaled];\
[ascaled][mask]alphamerge[masked];\
[1:v]scale=480x360[background];\
[background][masked]overlay=120:20"\
-c:a copy 65B6354F61B4AF02_HD_sq.MOVI am using "rotate" directly from an example in an attempt to get something to run at all.
The error I get back is :
[Parsed_rotate_3 @ 0x7ff4476045e0] [Eval @ 0x7fff5b3e3f00] Undefined constant or missing '(' in 'T*t)'
[Parsed_rotate_3 @ 0x7ff4476045e0] Error occurred parsing angle expression 'A*sin(2*PI/T*t)'
[Parsed_rotate_3 @ 0x7ff4476045e0] Failed to configure output pad on Parsed_rotate_3
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #1:0If I remove ’A’, ’T’, ’sin’, etc, rotate does actually work, but far from the desired behavior.
Am I missing something to expose those params ?
