  • How do I configure vlc/ffplay/cheese (or other) to automatically cycle/rotate between my 3 webcams ?

    9 janvier 2019, par fivedogit

    I have 3 webcams which register in Ubuntu 18.04 as /dev/video0, /dev/video1 and /dev/video2. All three show up fine in Cheese and ffplay (but not vlc for some reason... not important for this question).

    What I want is to open a viewing window and have the image shift automatically from device 0 to device 1 to device 2 and back to 0 every X seconds without the window closing or resizing.

    I think the ultimate solution will come from creating a fake video device (let’s say /dev/video3), watching it with a program and using ffmpeg or other command-line scripts to change the stream of /dev/video3. (v4l2loopback seemed promising)

    Unfortunately, I have spent a few hours on this and gotten nowhere. Any help would be appreciated.

  • Combining background video, audio, text and image to create a new vertical 1080*1920p video using ffmpeg

    3 mars 2023, par Arya Anish

    How can I combine background video, text and image to create a new vertical 1080*1920p video using ffmpeg. The text is contained in a sentences.txt file and each sentence is seperated by a line. Each senetence should stay on the video for n seconds. (for eg. 2 seconds) I tried using ChatGPT but, I quit, I spent 2 hours debugging and I don't want to do so for another 10 hrs.

    


  • ffmpeg -ss timeofday timecode

    19 mai 2014, par user3653763

    I’m trying to trim a 2 hour audio wav file at a specific timeofday timecode not start of file. Here is my code :

    ffmpeg -ss 18:11:54.14 -t 00:16:17.04 -i audio.wav -acodec libfaac -b:a 128k -af "volume=6dB" output.aac

    The error I’m getting is :

    Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)

    I’m assuming I get this error because my audio file is 2hours long, not 19 hours long. How can I adjust that ?
