ffmpeg fails on conversion from .mov to .mp4 fails aT 98%
3 avril 2013, par user2241249Our code is below. When converting a uploaded
.mov
to.mp4
the conversion halts at 98%.Almost all of our other preferred formats encode flawlessly. Anyone has any clue on where we went wrong ? We are struggling on this for a while now so we want to ask the experts, thanks in advance for any help.

ffmpeg - scaling and stacking 2 videos ?
25 mai 2016, par Gambit2007I have 2 inputs and i want to scale, crop and put them on top of each other at the same time. My command should look something like this :
ffmpeg -i input1 -i input2 -filter_complex crop=10000:5000:1000:0,scale=3840:1536 vstack output.mp4
I know i need to use chaining (?) but i tried to look it up online and couldn’t really get it to work.
So what would be the correct syntax the scale and crop both inputs and then put them vertically on top of each other while using ’-filter_complex’ only once ?
Thanks !
