How to pass command line arguments to FFMpeg in iOS
23 septembre 2014, par Arif NadeemThis is a beginner question, since I am new to iOS(I started it today), so please pardon my ignorance and lack of iOS knowledge.
After building and successfully using FFMpeg for Android I wanted to do the same for iOS.
So I built FFMpeg successfully for iOS by following this link, but after all that pain I am confused as how to use FFMpeg in iOS, I mean how can I pass command line arguments tolibffmpeg.a
file ?I am assuming that there must be a way to run the .a file as an executable and then pass command line arguments and hope for FFMpeg to do the magic, I did the same in Android and it worked beautifully.
I am also aware that I can use ffmpeg.c class and use its main method, but the question remains ; how do I pass those command line arguments ?
Is there something I am supposed to be aware of here, is the thing what I am doing now correct or am I falling short on my approach ?
I wanted to mix two audio files, so the command for doing that would be
ffmpeg -i firstSound.wav -i secondSound.wav -filter_complex amix=inputs=2:duration=longest finalOutput.wav
, how do I do the same in iOS ?Can someone please shed some light on this ?

Using FFmpeg to encode 2pass mp4
30 juin 2016, par Erin.YangI am trying to use FFmpeg to encode my 4K mp4 file to a 2pass 265 mp4 file for the purposes of testing. I am new to video compression and hope I’m making a simple mistake that someone can correct.
All infos in command line as below :

May I use OpenCV in a customized FFMPEG filter ?
20 mai 2016, par CodecodeupI am new to FFMPEG and OpenCV. I hope to overlay a heatmap video on top of a video. There could be two solutions :
(1) Make a customized FFMPEG filter. When looping over each frame, calculate the heatmap for that frame and overlay it with the video frame. Here, I need some matrix operations to calculate the heatmap. May I use OpenCV for these operations inside the FFMPEG filter ?
(2) Generate the heatmap, using OpenCV, as a video and then use FFMPEG to overly the heatmap video on top of the original video.Looks like the first one fits the FFMPEG workflow, but I am still not sure which solution is better, or if there are better solutions. Especially, I am not sure if I can use OpenCV inside FFMPEG.
Thanks.
