  • Error decoding timecode using ffprobe

    16 novembre 2016, par Pablo Montilla

    I’m using ffprobe to get timecode from an mxf which has DF timecode but with a non DF frame rate. I’m getting the error Drop frame is only allowed with 30000/1001 or 60000/1001 FPS.

    I’m running ffprobe -i "IMX 10Bit.mxf" and getting the following :

  • ffmpeg generates file with only audio from ts

    8 novembre 2016, par Seoman

    I’m trying to get some parts of a ts video and then merge them into a new video. The problem is that when doing the split, the video is lost. The splits only contains audio. Here is the video source information :
