  • ffmpeg : concat videos with different number of streams

    I'm having trouble with concatenating two videos with different number of streams. Please see the number of streams in both the videos below :

    So, clearly the video 1 has two streams and video 2 has three streams. Could someone please let me know how can I concatenate them ?

    


    I have tried :
ffmpeg -y -f concat -safe 0 -i /path/to/files.txt -codec copy /path/to/output.mov

    


    But it gives the following error :

    In my situation, sometimes the videos have same number of streams and sometimes different number of streams (with only video stream or with both video and audio streams). Ideally, I'm looking for an ffmpeg command which works in both situations. Is it possible ?

    


  • ffmpeg - spark - azure databricks - error writing trailer of "filename.mp3" : Operation not supported

    4 juillet 2021, par CRAFTY DBA

    I have been trying to figure out this tough problem.

    


    I am trying to convert *.mp4 files to *.mp3 files.

    


    I tried using MoviePy but I found out that is uses ffmpeg and was having the same issue.

    


    I used these two articles to get the latest version of ffmpeg installed on the Azure Databricks Cluster during startup. I am using a single node cluster for this POC code.

    


    Pyspark : Use ffmpeg on the driver and workers
    
https://ubuntuhandbook.org/index.php/2020/06/install-ffmpeg-4-3-via-ppa-ubuntu-18-04-16-04

    


    The issue is that even the simplest command results in errors.

    


    %%bash ffmpeg -i /dbfs/Craftydba/recording.mp4 /dbfs/Craftydba/recording.mp3

    


    I even tried .wav as an output format and still the same issue.

    


    I retested this command on a Data Science VM in Azure with Python and FFMPEG. It works fine on that OS/Build.

    


    It has something to do with the version of the code on the spark cluster.

    


    Any help is appreciated.

    


    Sincerely

    


    John Miner

    


    PS : I am add a dump of the OS version as well as a ffmpeg error.

  • FFMPEG muxing overhead unknown creating HLS Live stream from mp4 files

    9 juillet 2021, par user72261

    I am using FFMPEG Concatenate to combine a number of mp4 files into a live HLS stream after around 40 seconds FFMPEG stops with error.

    


    I am working in PHP launching the FFMPEG command from there using exec as this project relies on users input from there own control panels.

    


    This is the error i am getting.

'" "' . $PLAYLIST_NAME . '" );


    


    All mp4 files are encoded to h264 with the same specifications and if the video has audio it is encoded to aac.

    


    I am also using the latest version of the FFMPEG binary for linux.

    


    Has anyone else faced this issue ?
