    rtdl -q -mc 5 -u 'https://roosterteeth.com/watch/gary-and-his-demons-season-1-still-the-one'

• download a series:

    rtdl -mc 5 -u 'https://roosterteeth.com/series/rwby'

• print a trace of the operations that would occur IF a series were to be downloaded:

    rtdl -dr -ll 2 -u 'https://roosterteeth.com/series/rwby' >'convert_mp4s.sh'
  
    rtdl -nm -mc 5 -i 'episode_urls.txt' >'log.txt' 2>&1
  
    ./convert_mp4s.sh

Suggestions:

1. download with options: --no-mp4 --log-level 3
   • redirect stdout to a log file
   • when download completes, check the log file for any error messages
   • if any .ts chunks encountered a download problem
     • identify the url of the Rooster Teeth page that was being processed when this error occurred
     • redownload that page (using the same --directory-prefix)
       • all previously downloaded data not be modified or deleted
       • only missing data will be retrieved
2. repeat the above process until the log file shows no download errors
3. finally, convert the HLS stream to mp4
   • to only convert the video and audio streams to mp4
     • the ffmpeg command to perform this conversion is included in the log file
     • when converting the episodes in a series, a list of all ffmpeg commands can be generated with the options: --dry-run --log-level 2
   • to convert the video and audio streams to mp4, and convert all vtt subtitle streams to srt
     • redownload (using the same --directory-prefix) without the option: --no-mp4
       • all previously downloaded data not be modified or deleted
