ffmpeg change timecode metadata inside video file
23 février 2024, par virtualsetsI have problems to change timecode inside metadata of a video file "mov"


ffmpeg -i input.mov -ss 0 -map 0 -acodec copy -vcodec copy -timecode 01:20:10:00 -metadata:s:2:0 timecode=01:20:10:00 -metadata:s:1:0 timecode=01:20:10:00 -metadata:s:0:2 -metadata:s:0:2 timecode=01:10:10:00 output.mov

I don't understand why it does not modify the timecode in the mov file. The old timecode remains.

Turn Mp4 File into Portrait Video
5 avril 2022, par Tech BreakerI recently programmed a bot, which uses the Twitch API to scrape Twitch videos, and then post them on YouTube. This is my youtube channel if you want to see an example : https://www.youtube.com/channel/UCuhWw8LbPWdkybIF9olAszw


The problem that I am having is I want to find a way to convert these regular twitch videos, into youtube shorts which I can automatically upload. The facecam does not need to be included, and the entire video can just be compressed into a 9:16 format.


I already tried FFMPEG but I don't know if I am doing it correctly, and really need help or advice on how to do this.


Here is an example of a video I would try to convert :
https://www.youtube.com/watch?v=hZecXrvd6_g


(excuse the explicit language, this is just the first video I saw on my bot channel)


Tldr : Convert mp4 file into a 9:16 video format


EDIT :


Command i ran : ffmpeg -i video.mp4 -vf scale=1280:720 output.mp4

audioread.NoBackendError on augmented audio files
23 mars 2019, par elongated spaceProblem :
I have applied a number of augmentation techniques such as pitch shift and stretching to a number of wav clips and have outputted them to a folder - Windows 10 plays these clips fine.
However, when i try to load these clips with librosa using the following code :
wav_clip, sample_rate = librosa.load(file_path, mono=True, sr=None)
i get "audioread.NoBackendError"
What I’ve Tried :
Installed ffmpeg using this video https://www.youtube.com/watch?v=xcdTIDHm4KM. to confirm it worked i entered the following into windows command line :
"ffmpeg -version"
Where i got an output of the version and configuration details.
I have also tried to import ffmpeg from the list of available packages in PyCharm, but i still get the error.
Am i missing something ?
All the original, unaltered wav files work and load fine.
