  • FFMPEG Combine multiple commands into one script

    16 février 2017, par ObeeWnn

    I need some help combining ffmpeg commands into a python or bash script :

    \Download
    
Youtube-dl URL
    

    
\Concatenate videos
    

    
WD = "C:\"

with open ('output.txt', 'w') as in_files:
    
    for eachfile in files: in_files.write('file \''+eachfile+'\'\n')
    

    
ffmpeg -y -f concat -i output.txt -c copy input.mp4
    

    
\Encode
    
ffmpeg -y -threads 16 -i input.mp4 -c:a libfdk_aac -vbr 4 -c:v libx264 intermediate1.ts

    This is to download videos, place an intro video in the beginning, draw text over intro, concatenate the videos, apply watermark throughout video, apply outro, create thumbnail, etc.

  • ffmpeg udp capture not working

    27 février 2017, par user3172852

    I have confirmed that there is incoming UDP packets at port 5968 of my computer with wireshark.
    However when I try to capture these packets with ffmpeg. After exiting (ctrl+c) I get no output, the output file is not even written to disk. This is what my terminal looks like.

  • WebM live streaming via DASH

    4 juin 2018, par ewack

    I am following the instructions here to try to make WebM live streaming via DASH. My input is from an Axis camera and it is streaming as h264 encoding. I am using node to spin up the ffmpeg processes. I am able to create the .hdr file and the .chk files. The .mpd file is even created but it’s empty and I get an error saying :

    Could not write header for output file #0 (incorrect codec parameters ?): Operation not permittedStream mapping: Stream #0:0 -> #0:0 (copy)

    Here’s all of my code :
