• The Ultimate YouTube-DL script [on hold]

  30 juillet 2018, par G. L.

  I need help creating/finishing a bash script. What I’m trying to do is to create the perfect YouTube-DL archiving script.
  As of now, the only thing I can do is download all of a Users’ videos, embed subtitles, add metadata but I want to also autosub the files (with script number 2) and convert the downloaded files with ffmpeg or AVConv or handbrake-cli and then remove the video files when I have a successful conversion.

  Script 1 (downloads videos skipping already downloaded ones)

  youtube-dl -i -o "%(title)s-%(id)s.%(ext)s" --all-subs --embed-subs --embed-thumbnail --add-metadata --sleep-interval=20 --rate-limit=1M --exec 'youtube-dl2kodi.py -t tvshow -f {}' --download-archive .archive $(cat url.txt) 

  Note : youtube-dl2kodi.py creates Kodi compatible nfo files so I can view them properly on Kodi with metadata.

  Script 2 (subtitles videos automatically using autosub)

  for file in *I WANT TO AUTOSUB files in this directory and subdirectories*
  
  do
  
    autosub -S de -D de "$file" >> results.out
  
  done

  I want to merge script 1 and 2 and then encode the files and remove original video files (mp4, mkv and webm) if successful.
  My encoding preference is HEVC with CRF 23 and I don’t want to encode the audio. I want to copy the audio. The final video would be a MKV file.

• avcodec/av1 : only set the private context pix_fmt field if get_pixel_format() succeeds

  22 mars 2022, par James Almer

  avcodec/av1 : only set the private context pix_fmt field if get_pixel_format() succeeds
  Otherwise get_pixel_format() will not be called when parsing a subsequent Sequence
  
  Header in non hwaccel enabled scenarios, allowing frame parsing when it shouldn't.
  This prevents the scenario seqhdr -> frame_hdr/redundant_frame_hdr -> seqhdr ->
  
  redundant_frame_hdr from having the latter redundant frame header parsed as if it
  
  was a frame header by the decoder because the former was discarded.
  
  Since CBS did not discard it, the latter redundant frame header is output with a
  
  zeroed AV1RawFrameHeader struct, which can have undesired results, like division
  
  by zero with fields normally guaranteed to be anything else.

  fftools/ffmpeg_dec : add decoder private data
  Move InputStream.decoded_frame to it.
  Analogous to what has been previously done for all the other major
  
  components.
