• python [WinError 2] the System Cannot Find the File Specified

  15 août 2024, par user26831166

  Code cant create a certain file
The thing is code isn't mine a took it from a friend and my friend get it from another person
and this 2 person can run code without any problem
but i have.

  Error i got after run the code

  


  = RESTART: D:\Bots\2vidpod.py&#xA;Traceback (most recent call last):&#xA;  File "D:\Bots\2vidpod.py", line 71, in <module>&#xA;    os.remove(os.path.join(output_folder, &#x27;temp.mp4&#x27;))&#xA;FileNotFoundError: [WinError 2] Не удается найти указанный файл: &#x27;D:\\bots\\ttvidads\\VID\\ZAGOTOVKI\\Videopod1\\temp.mp4&#x27;&#xA;</module>

  


  so things i checked is
path is right
programs is installed FFMPEG and PYTHON all additional libraries downloaded
i pretty sure error caused by regular path and i wanna know if absolute path can do the thing

  


• Convert video to mp3 with album art with ffmpeg

  30 mars 2014, par dave

  Using ffmpeg, I want to extract only the audio of a video and turn it to an mp3, in addition, I want to add some meta information including an image to the mp3.

  I can do each of these separately.

  First, extracting the audio :

  fmpeg -i video.mp4 -f mp3 -vn -b:a 192k -ac 2 -ar 44100 -aq 5 -y out.mp3

  Second, add the image and meta info :

  ffmpeg -i out.mp3 -i image.jpg -map 0:0 -map 1:0 -c copy -id3v2_version 3 -metadata:s:v title="Song Title" -metadata:s:v comment="This Song" -c:a:0 -y out2.mp3

  What I'd like to do however is have this in a single command. This is the question. How do I combine these two into a single workable command (if possible). When I try to combine them, I get issues with no input streams.

  Thank you !

• ffmpeg crop in a loop crops files incrementally

  13 septembre 2014, par Voprosnik

  I have a very large audio mp4 file that contains several songs.

  I have generated a script which reads a text file with the times and the song names and successfully assigns starttime, endtime and songtitle in 3 variables. The script successfully echoes the variables and returns the following format :

  00:00:00 00:10:15 Song1
  
  00:10:15 00:14:20 Song2

  and so on...

  Now I am intending to use this script with ffmpeg and crop each part of the big file into smaller audio files.

  The script thus, after feeding the variables in a while loop, it reaches to the command

  ffmpeg -ss $START -t $END -i ${1} -acodec copy $SONGNAME.mp4

  Then I realized that the -t option doesn’t refer to the end point of the excerpt, but the duration. Eg. when I attempted to crop a song from 10:00 to 12:00 it resulted to a 12 minutes long sound file, far longer than the song itself. This resulted in increasingly bigger files.

  Therefore I found some date-manipulating algorithms. Subtracting $START from $END results to an integer with the song’s duration in seconds. I tested it by echoing the results and it resulted to realisting figures (around 100-200).

  However when I replaced the -t option with $DUR instead of $END, this resulted also to increasingly larger files. I didn’t measure the exact length of each, but it seems that the duration increased itself by each loop. I also added an echo $DUR line, which returned the realistic amounts it should. However the ffmpeg -t $DUR did not seem to agree.

  PS. -t has two options, input (before -i) and output (after -i). When I use it after the -i as output (i.e. the duration of the output file) it SEEMS to work, at least it generates realisticly sized files. The question remains why it behaves strangely in the first place.
