• Sync Multiple Video sources based on audio

  14 octobre 2016, par linuxer

  I have 6 videos from 6 separate cameras that I need to sync up. They don’t all start at the same time, and so I am thinking the best route would be based on audio. Is there a way to do this with ffmpeg, or is there a library for C# that I can use ?

  The result needs to be that the 6 videos are synced based on audio, and then trimmed so they are all the same length and audio matches up.

  I am really hoping there are some tools to simplify this, but in my searching I haven’t seen anything.

• Superimposing two videos onto a static image ?

  15 décembre 2014, par Archagon

  I have two videos that I’d like to combine into a single video, in which both videos would sit on top of a static background image. (Think something like this.) My requirements are that the software I use is free, that it runs on OSX, and that I don’t have to re-encode my videos an excessive number of times. I’d also like to be able to perform this operation from the command line or via script, since I’ll be doing it a lot. (But this isn’t strictly necessary.)

  I tried fiddling with ffmpeg for a couple of hours, but it just doesn’t seem very well suited for post-processing. I could potentially hack something together via the overlay feature, but so far I haven’t figured out how to do it, aside from pain-stakingly converting the image to a video (which takes 2x as long as the length of my videos !) and then superimposing the two videos onto it in another rendering step.

  Any tips ? Thank you !

  Update :

  Thanks to LordNeckbeard’s help, I was able to achieve my desired result with a single ffmpeg call ! Unfortunately, encoding is quite slow, taking 6 seconds to encode 1 second of video. I believe this is caused by the background image. Any tips on speeding up encoding ? Here’s the ffmpeg log :

  Update 2 :

  It works ! One important tweak was to move the underlay.png input to the end of the input list. This increased performance substantially. Here’s my final ffmpeg call. (The maps at the end aren’t required for this particular arrangement, but I sometimes have a few extra audio inputs that I want to map to my output.)

• FFMPEG Unable to Decode Quicktime QDMC Stream (No decoder for stream)

  9 janvier 2017, par mbmast

  We are using FFMPEG to convert iPhone video to MP4. This requires an AAC decoder which is not included in any binary distributions of FFMPEG (due to licensing issues). The solution is to download the FFMPEG source and compile it yourself. I’ve done this, apparently incorrectly, as I cannot decode the audio stream. I am getting this error :

  Error opening filters!

  I suspect that I failed to compile and include the correct codec library when I built FFMPEG. The problem is I don’t know which library I should have built/included. I haven’t found anything that says to decode QDMC audio in FFMPEG you need the XXXXX library.

  Here’s the complete list of decoders that my build supports :
