  • FFmpeg opening key info file - could not write header for output file

    13 mars 2021, par Hoang Nam

    I want muxer mp4 to m3u8 with key.
I can do this when I put all files in same directory.

    


      

    • File 480.mp4.key

      • 


    • File video 480.mp4

      • 


    • File hls info have name : "480.mp4.keyinfo"

      • 


    


    When I run the command ffmpeg -i 480.mp4 -hls_time 10 -hls_key_info_file 480.mp4.keyinfo output.mp4.m3u8
everything runs normally.

    


    However, I meet a problem when I move file "480.mp4.key" and file "480.mp4.keyinfo" into another directory such as /usr/local/WowzaStreamingEngine/keys/auto_scan/testhh/2/123/480.mp4.keyinfo
I also change key directory in file keyinfo

    


    After that I run

    


    ffmpeg -i 480.mp4 -hls_time 10 -hls_key_info_file 480.mp4.keyinfo output.mp4.m3u8 ffmpeg -i output/testhh/2/123/480.mp4 -hls_time 10 -hls_key_info_file /usr/local/WowzaStreamingEngine/keys/auto_scan/testhh/2/123/480.mp4.keyinfo output/testhh/2/123/480.mp4.m3u8


    


    But I get an error :

    


     error opening key info file /usr/local/WowzaStreamingEngine/keys/auto_scan//testhh/2/123/output/testhh/2/123/480.mp4.keyinfo

  • Fetch an input file dynamically in a batch file to perform operations on it

    25 mars 2019, par Piyush — ,

    I have created a which uses to extract frames of a video to .jpg.

    ffmpeg -i sample.mp4  -r 5 E:\frames\createdFrames%%d.jpg

    It works completely fine and created the desired frames, however I want to give the sample video dynamically, i.e. pass it when the batch file is being executed.

    How can I pass the input file dynamically ?

    If possible, also discuss how to store the file dynamically, i.e pass the directory where I want to store the file when the batch is being executed.
