• Ffmpeg rounds seconds instead of using the milliseconds part

  10 mai 2021, par NourElDineA

  I tried to cut a video using the following command :

  


  ffmpeg -i input.mp4 -ss 00:00:00 -to 00:00:06.600 output.mp4


  


  When I run the command ffmpeg rounds up and the output video is 7 seconds instead of 6.6 seconds.
I would like to know if there is a way to cut the video precisely where I tell it to.

  


  Here is the log file content :

  The output file is 7 seconds long which means ffmpeg rounded up my 6.60 to 7 and I need it to cut exactly at 00:00:06.60

  


• Whisper openAI with colab : error message [duplicate]

  9 juin 2024, par user35117

  Up to now, i succeed in using Whisper with Colab (with GPU execution and model v3 ) without error message.
But today, i'm facing to an error message.
Firstly i execute successfully these 2 following commands :

  


  !pip install git+https://github.com/openai/whisper.git
!sudo apt update && sudo apt install ffmpeg


  


  Then, when i execute this third following command :

  


  !whisper "88_89_90_91_103_104_105_106_100.mp3" --model large-v3

  


  I obtain an error message. Please find below the whole error message :
Do you know where the probleme would be come from ? I double checked the name file.

• Converting MTS to MP4 using FFmpeg results in no/missing audio

  17 mars 2021, par tenninebt

  I have a few videos coming from a Sony Nex-5N. Basically they are "compiled" in an AVCHD. The format that is inside is MTS. I'm able to convert the videos losslessly but the resulting MP4 has no audio.

  


  ffmpeg -i 20201205150626.MTS -c:v copy -c:a copy -an -f mp4 20201205150626.MP4 


  


  The result is no audio. Then I tried to select explicitly the audio track using -map 0:a:1 but it says that it does not matches no streams. Please have a look at the following extract :

  


  > ffmpeg -i 20201205150626.MTS -c:v copy -c:a copy -map 0:a:1 -an -f mp4 20201205150626.MP4
