What video codecs work on Google Chromebook
3 mars 2019, par MonkeyDLuffyI’m trying to put a show on my friends Google Chromebook but the mp4 files show up black when trying to watch them on said Chromebook, audio works fine. I found out that it is a video encoding problem but I cannot find a list of video formats that work on the Chromebook. I have ffmpeg and handbrake to try and test some things, but if someone could tell me a ffmpeg code that will convert the video files into a format that works on a Google Chromebook that would help a lot.
What I’ve tried :
ffmpeg -i "Game of Thrones S02E01 The North Remembers.mkv" codec mpeg "Game of Thrones S02E01 The North Remembers.mp4"
Which gives error :
[NULL @ 00000177196ea500] Unable to find a suitable output format for
’codec’ codec : Invalid argument -
pyAudioAnalysis to recognize the beginning of a video
22 mai 2022, par AlonBRI have a video beginning with a 5,4,3,2,1 beeping (similar to : https://youtu.be/67lnjV6SrFw). the sound is recorded alongside ambiant sounds. Using ffmpeg I can easily extract the audio.
I am basically asking two questions :


- 

- Can I use ffmpeg-python's
ffmpeg.input('file.mp4').audio
as an input to perform pyAudioAnalysis's functions on ? - Can pyAudioAnalysis recognize the beeping (i.e. I can input an audio of the beeping and the audio of the video) to find the time in which the beeping ends ?








edit : I've been thinking of something similar to ORELIA software


- Can I use ffmpeg-python's

How can I play a video from the CLI with no output of video or audio
1er janvier 2023, par GaryI have 1000s of video files and I know some of them are corrupted. I want to be able to detect corrupted files with a bash script, I tried using FFmpeg with error logging :


ffmpeg -v error -i "vid.avi" -f null - 2>"vid.log"



The output doesn't seem to be very useful though, some files which report errors play without any problems. The only way to know for sure seems to be to watch the video to see if there is any corruption or if it crashes the media player.


I would like to be able to automate the "watching" by playing the video from the command line and detecting the corruption or crashing there but I can't find a way to run it without outputting the video and audio.


I have tried FFplay but I can only disable one of the outputs not both :


ffplay -nodisp "vid.avi"
ffplay -vn "vid.avi"



These disable the video :


ffplay -an "vid.avi"



This disables the audio but I can't combine them, when I do I get an error :


Failed to open file 'vid.avi' or configure filtergraph



I have tried using the vlc/cvlv suggestions I have found but none have worked, it still opens a graphical interface just with no controls.


Is there any way to do this ?
