• ffmpeg doesn't recognize Quicktime DV codec

  8 août 2017, par 3pointedit

  I have had success with excellent advice, on a Mac OSX10.5, converting a modified MXF media structure to h264 while retaining multitrack audio. But I cannot get ffmpeg to work in Windows environment.

  See this page.

  Here’s the result of latest failure-

• ffmpeg output parse in batch script

  5 juin 2022, par vlad2005

  I am totally unfamiliar with scripts in Windows, but are forced to use such a script. I would like someone to help me with the following problem. I want to process the output from ffmpeg command to save information about access an webcam to be used later.
More precisely command is following :

  



  ffmpeg -stats -hide_banner -list_devices true -f dshow -i dummy


  



  and output is like this :

  



  [dshow @ 02cec400] DirectShow video devices (some may be both video and audio devices)
[dshow @ 02cec400]  "Microsoft LifeCam Studio"
[dshow @ 02cec400]     Alternative name "@device_pnp_\\?\usb#vid_045e&pid_0772&mi_00#6&2a15e69b&0&0000#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\global"
[dshow @ 02cec400] DirectShow audio devices
[dshow @ 02cec400]  "Desktop Microphone (3- Studio -"
[dshow @ 02cec400]     Alternative name "@device_cm_{33D9A762-90C8-11D0-BD43-00A0C911CE86}\Desktop Microphone (3- Studio -"
[dshow @ 02cec400]  "Line In (High Definition Audio "

[dshow @ 02cec400]     Alternative name "@device_cm_{33D9A762-90C8-11D0-BD43-00A0C911CE86}\Microphone (High Definition Aud"


  



  Typically, the first two occurence for ”Alternative name” from DirectShow correspond to video and audio, so for simplicity I want these two information saved in two variables.
In this example is :

  



  @device_pnp_\\?\usb#vid_045e&pid_0772&mi_00#6&2a15e69b&0&0000#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\global


  



  and

  



  @device_cm_{33D9A762-90C8-11D0-BD43-00A0C911CE86}\Desktop Microphone (3- Studio -


  



  Can someone more experienced to help me with this task ?
Thanks in advance !
