  • FFmpeg wrong duration(double) when convert mp4

    13 novembre 2017, par crazymxm

    The output file has the double duration :

    Source video duration :00:01:58.88

    output video duration :00:03:57.76

    （video’s duration is double ，audio’s duration is correct. So， the video looks like played twice, with no sound in the second half ）

    here is the log：

  • FFMpeg - Split Window RTMP - Delay on Second Stream

    22 février 2016, par Nick Smit

    I’m trying to combine two live RTMP sources into one split screen output with combined audio. The output is then sent on to a receiving RTMP server.

    Using the following command, which uses the same RTMP input for both feeds, I’ve managed to get the above working, however the input on the left is delayed by about 2 seconds from the one on the right.

  • Images to video in Prezi format

    13 juin 2016, par sammy34

    I have five *.jpeg image files : m01.jpeg to m05.jpeg.

    I’d like to make a video of a sequence of these five images and upload it to Prezi to use in a presentation.

    FFMPEG seems to be the tool for the job here. I am generating a video using the following command :

    ffmpeg -r 2 -i m%02d.jpeg -pix_fmt yuvj420p myvideo.mp4

    This generates a video that I can play fine locally. Unfortunately, when I try to upload the video to Prezi, I always get the following error...

    "Technical details: id: 2110 the reason is: Event [Event type="stateChange" bubbles=false cancelable=false eventPhase=2]"

    ...which isn’t particularly informative.

    If I upload a sample MP4 from the web to Prezi, it works fine.

    My question : Does anybody know what I need to give FFMPEG as parameters here so that it will generate a Prezi-compatible video from these images ?

    EDIT : As requested, here’s the complete console output for FFMPEG. Unfortunately there are no glaring warnings or errors that I can see.
