  • How can I convert multiple images to a video file while keeping the same file name ? [duplicate]

    13 juillet 2015, par Ertzi

    This question already has an answer here :

    My intention would be to get at the same time, picture1.jpg, picture2.jpg, picture3.jpg to video format such as picture1.mp4, picture2.mp4, picture3.mp4.

    I am currently using Mencoder and Linux bash code mencoder mf: //*.jpg -mf w = 1366: h = 768: fps = 6/60: type = jpg -ovc copy -oac copy -o images.mp4. But this command makes all the images into one video file (images.mp4).

    Can I do it with mencoder or ffmpeg ?
    My linux bash coding skills are basic.

  • Using ffmpeg, extract small part of .m4a audio file and set extract file duration correctly

    30 août 2015, par Kes

    I have Linux mint 17.1.

    When I use ffmpeg to cut out a section of a 4 hour long .m4a audio file as follows :

    ffmpeg -ss 0:10:00 -i in_file.m4a -vn -c copy -t 0:40:00 out_file.m4a

    the correct position and duration of extract is extracted and the file plays just fine, but the audio duration meta-tag in the playback player is incorrectly shown as 4 hours.

    How can I set the actual extract duration so it is correct, in this case 30mins, or even better get ffmpeg to calculate it and set it properly ?

    Thank you

  • copy .wav audio file settings to new .wav file

    18 novembre 2020, par Jonas

    currently I am working with a speech to text translation model that takes a .wav file and turns the audible speech within the audio into a text transcript. The model worked before on .wav audio recordings that were recorded directly. However now I am trying to do the same with audio that was at first present within a video.

    


    The steps are as follows :

    


      

    • retrieve a video file from a stream url through ffmpeg
    • 


    • strip the .aac audio from the video
    • 


    • convert the .aac audio to .wav
    • 


    • save the .wav to s3 for later usage
    • 


    


    The ffmpeg command I use is listed below for reference :

    


      rm /tmp/jonas/*
  ffmpeg -i {stream_url} -c copy -bsf:a aac_adtstoasc /tmp/jonas/{filename}.aac
  ffmpeg -i /tmp/jonas/{filename}.aac /tmp/jonas/{filename}.wav
  aws s3 cp /tmp/jonas/{filename}.wav {s3_audio_save_location}


    


    The problem now is that my speech to text model does not work on this audio anymore. I use sox to convert the audio but sox does not seem to grab the audio. Also without sox the model does not work. This leads me to believe there is a difference in the .wav audio formatting and therefore I would like to know how I can either format the .wav with the same settings as a .wav that does work or find a way to compare the .wav audio formatting and set the new .wav to the correct format manually through ffmpeg

    


    I tried with PyPy exiftool and found the metadata of the two files :

    


    The metadata of the working .wav file is enter image description here

    


    The metadata of the .wav file that does not work is enter image description here

    


    So as can be seen the working .wav file has some different settings that I would like to mimic in the second .wav file presumably that would make my model work again :)

    


    with kind regards,
Jonas
