• 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.

  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 ?

  


• Streaming an IP camera through node.js

  18 juillet 2021, par Jacob

  I am trying to get an IP camera stream to run in the browser, and eventually phones. However, I am running into a problem accessing the RTSP stream through ffmpeg.
I am running the command below, substituting the correct info. I changed the camera to a static IP address and copied the IP address to STATIC_IP.

  


  /opt/homebrew/bin/ffmpeg -i rtsp://USER:PASS@STATIC_IP:554/stream1 -fflags flush_packets -max_delay 5 -flags -global_header -hls_time 5 -hls_list_size 3 -vcodec copy -y .\videos\ipcam\index.m3u8
