• ffmpeg - convert MP4 to Panasonic Lumix playable MJPEG [closed]

  21 août 2024, par Maro Natts

  I'm new to ffmpeg and ffprobe, I started using it to convert videos to show on 3DS and DSi for an art project.

  


  Now I want to show my own videos on a Panasonic LUMIX digicam (DMC-FT2)(JPN), but have had trouble getting the device to play the video.

  


  The digi takes videos in AVCHD Lite and Motion JPEG.

  


  I've tried online converting mp4 to the respective formats + changing file name, but the device only recognises that it's there — refuses to/can't play it.

  


  I also tried using this code to convert to MJPEG :
ffmpeg -i input.mp4 -c:v mjpeg -q:v 2 -an output.mjpeg

  


  But no luck ! Changed the filename to match the others, the camera recognised the file is there, but can't play it.

  


  So I used this code to get the information of a MJPEG video taken on the digi :
/opt/ffmpeg/ffprobe file.mp4 -show_streams  -select_streams v  -print_format json

  


  and got the following, is it possible to convert my own video (mp4) to these settings ? So that it can play on the device ? If so how ?

  


  Thanks !

• Alexa developer console gives me "The audio is not of a supported MPEG version" Error

  20 mars, par Boban BoBo Banjevic

  I am trying to make an Alexa skill, and I am using audio mp3 files stored is S3, lambda function has access to my DynamoDb and ultimately S3. But I have an issue with my audio files. I keep on getting "The audio is not of a supported MPEG version" when I test alexa skill. I tried multiple ffmpeg -i file conversions.

  


  When I type ffprobe -v quiet -print_format json -show_format -show_streams "Piano.mf.A1.audio10.mp3" this is what i have for my file down below :

  It should be everything that is required, am I doing something wrong, this is the only thing stopping me from finishing the skill. Asking ChatGPT said it could be because of the mp3float, and after many conversions it still doesn't work.

  


• 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 ?
