  • Invalid data found when processing input. No start code is found

    23 septembre 2020, par Alex Blokha

    I am trying to concat video from many files.
But sometimes I receive an error : "Invalid data found when processing input".

    


    So, I am trying to iterate over files with ffprobe and find invalid files.
Here is the error.

    Questions :

    


      

    1. How can this be fixed, so I don't need to iterate with ffprobe and just use concat (command line : f :\prog\ffmpeg\bin\ffmpeg.exe -f concat -safe 0 -i mylist.txt -c copy output-xx.avi) ?

      2. 


    2. If not, how can I receive an error in my .bat file and move "invalid" file to "Error" folder ?

      3.

    I referred link1, link2 to understand the problem but could not find a solution.

    


  • MLT query video_codecs not listing libx264

    7 juillet 2020, par Terryn94

    Querying video codecs does not list libx264 as an available codec

    


    [terry@localhost ~]$ melt -query video_codecs | grep 264
  - h264_nvenc
  - h264_v4l2m2m
  - h264_vaapi
  - nvenc_h264
  - h264
  - h264_cuvid


    


    But I can use it in a command such as :

    


    melt avformat:DarkStar.webm -consumer avformat:output.mp4 acodec=aac vcodec=libx264


    


    and it works successfully.
This is causing a problem with kdenlive. When selecting Render and choosing the format MP4 - the dominating format (H264/AAC) the render option is disabled with the error Unsupported video codec : libx264.

    


    kdenlive checks the profile codec against the list obtained from MLT using :

    


    Mlt::Properties vcodecs(mlt_properties(consumer->get_data("vcodec")));


    


    which seems to get the same list as query video_codecs.

    


    For info here is what ffmpeg says about the codecs :
