• using default poster image with video and audio tags

  23 décembre 2016, par Ravinder Payal

  I have a web-application where users can share music and videos ( will be saved on sme-server utilized by Web-Application ) and as we know some audio /video files have posters/thumbnails included/attached with them.
  NOW, I want to show those posters with audio or video in HTML5.
  I know about poster tag, but it needs a separate image file to show. However, I want to show image file attached with song (audio / video).
  Any suggestion related any java-script or HTML api will be appreciated.
  I know about obtaining poster images with ff-mpeg(or similar libraries), but that will add an extra work load on my server. Thanks.

  Note :-I may consider any server side efficient solution alo.

  Thanks in advance.

• Discord v13 audioPlayer playing state changed to idle for unknown reason

  14 septembre 2021, par zS1L3NT

  When I play a song, the audioPlayer's state goes from buffering to playing to idle for no reason, without throwing any errors too. The weird thing is that the code I made runs perfectly fine on my Windows 11 Laptop. The error only occurs when I run the exact same code on my Ubuntu VPS. Here is the dependency report when run on the Ubuntu VPS

• How to encode specific metadata version in FFMPEG ?

  11 février 2021, par Charlie Britton

  I am batch converting lots of songs into shorter "Advert" songs for SHOUTcast and to be recognised as adverts by the server. The song must have ":Advert" for both the title and the artist metadata tags. When I use the following command :

  



  ffmpeg -i "$i" -c copy -vn -map_metadata -1 -metadata title=":Advert" -metadata artist=":Advert" -t 120 "adverts/ADVERT_$i"


  



  I would expect it to output the song with only ":Advert" as title and artist metadata but when I import it into the radio playout software (using ID3 1.x tagging) the metadata has not copied across and is therefore lost. Output from ffmpeg :

  I believe this is happening because the tag names are different (e.g. title should be title, but is TIT2 when output. Please could someone specify how I could ensure that the metadata is encoded in the ID3 1.x format so that it is readable by the radio playout software. Many thanks.
