Overlaying video with text - ffmpeg speed
12 février 2017, par SebadcI’m developing an app that has a functionality similar to Snapchat’s, in which you can add text to an existing video and save it on your phone.
I got this to work using ffmpeg’s "-drawtext" filter. The problem is that I’m getting a noticable delay (20 seconds or so) when adding text to videos, even though they are not too big (around 10 seconds length).
Can anyone point me in the right direction on how to reduce this delay ? Taking Snapchat as reference, they overlay high quality videos with text with little to no delay.
I’ve read about extracting the video’s frames and overlaying them manually, but shouldn’t that take longer ?
Thank you for your help.

ffmpeg : How to change video duration (slow-down or speed-up) to exact value ?
2 février 2017, par MooI have miltiple videos with different durations and need to always set it to be exactly 10 seconds.
I know that I can use
-filter:v "setpts=speed*duration"
but is there any way to make a universal one-line function to convert any-duration video to 10 seconds video ?
