• Issue with downloading read-only recordings on Teams [closed]

  26 août 2023, par Ankit

  I have been following this guidance to download read-only Microsoft Teams recordings until last month (early July'23) successfully. But now when I am trying the same steps and everything, I am getting some error (given below for reference).

  


  The code that I am trying in CMD -

  


  ffmpeg -i "PASTE_YOUR_COPIED_REQUEST_URL_HERE" -codec copy NAME_OF_DOWNLOADFILE.mp4


  


  The error that I am getting now -

  


  [tls @ <some number="number">] Error in the pull function.&#xA;[tls @ <some number="number">] IO error: Error number -10054 occurred&#xA;[in#0 @ <some number="number">] Error opening input: Error number -10054 occurred&#xA;Error opening input file &#xA;Error opening input files: Error number -10054 occurred&#xA;</some></some></some>

  


  I am running Windows 10 Enterprise 64-bit version.

  I have tried the following things, but they didn't help -

  


  

  1. Tried downloading inherently downloadable recordings (that are un-protected, non view-only videos)

  


  2. Removing some parts of the URL as highlighted/suggested by some Reddit users

  


  3. Tried different browsers (Edge and Chrome)

  


  4. Tried refreshing my ffmpeg folder with latest version

  


  5. Tried running the command in cmd with 'Run as Administrator' option

  


  


  Please suggest how shall I download read-only Teams recording using either ffmpeg or some other tool ?

  


• How to change HLS quality in ijkplayer for flutter or alternative solutions ?

  28 mai 2024, par gh05t

  Hi can anyone help me with this issue, we decided to use the flutter ijkplayer as it's the only player on flutter that supports the option to change playback speed, but it doesn't have the option to change the hls quality, and neither does any other player as per my findings, if anyone knows please share.

  


  As for what I've tried, I download the file and split it into 4 files with each file having only one video and audio stream and use a button to change the file.

  


  I also tried to look into changing the tracks from master with the player but while FFMpeg does support this, I'm not sure how to do that from flutter.

  


  Currently it works, but the splitting is hardcoded and might need to be changed for different master m3u8(we use vimeo and expect the same file format for master m3u8 but they can change it down the road or we could change service for video), and it would be preferable to change streams from the player itself instead of using an external ui button which for example won't be available in full screen mode, which you would expect most people to watch the video in.

  


  I'm trying to make the splitting part more generalized but would like to know how others handle this problem.

  


  


  Edit I've made the splitting somewhat dynamic, but I just came across another issue, in ffmpeg(complied in the ijk player it is 4-5 years old not the latest version) I have to use format option - protocol_whitelist,'http, https, tls, file, crypto, tcp, udp, concat' so I can play local file, but the player by default sets the format option - fflags 'fastseek' to allow playing faster than 1, but for some reason that functionality breaks the fastseek, or in other words, if I play local file I can't use speeds greater than 1, which I can on files I play from the internet.

• lavc/avpacket : fill padding area on side data split.

  1er juin 2013, par Clément Bœsch

  lavc/avpacket : fill padding area on side data split.
  The padding data is assumed to be 0 in several places, notably in
  
  subtitles. This problem was not detected with fate-sub-srt test because
  
  the first element of the side data (x1) is 0 in the test, so the
  
  trailing side data present in the packet wasn’t read by the decoder. The
  
  issue can be observed with a large enough x1.
  It is also noted in FF_INPUT_BUFFER_PADDING_SIZE doxy that MPEG
  
  bitstreams require that padding with 0, so it might fix other issues.
