  • ffmpeg : Unrecognized option 'alpha_quality'

    16 avril 2024, par László Monda

    I want to make transparent videos work in Safari, which doesn't support WebM for this purpose but only H265 with alpha transparency.

    


    According to this post, I used Shutter Encoder, but only some of its versions work for this purpose on Mac.

    


    Instead of using Shutter Encoder on Mac, I want to use ffmpeg on my Linux PC. Shutter Encoder uses the following command in the background :

    


    ffmpeg -threads 0 -hwaccel none -i input.mov -c:v hevc_videotoolbox -alpha_quality 1 -b:v 1000k -profile:v main -level 5.2 -map v:0 -an -pix_fmt yuva420p -sws_flags bicubic -tag:v hvc1 -metadata creation_time=2024-04-14T14:53:08.734684Z -y output.mp4

    


    which yields the following output on my PC :

Unrecognized option 'alpha_quality'.
Error splitting the argument list: Option not found


    


    When googling for "Unrecognized option 'alpha_quality'.", there are no results, which I find very odd.

    


    What's going on, and how can I make ffmpeg work for this purpose without Shutter Encoder ?

    


  • HLS. FFmpeg : error when loading first segment [closed]

    30 avril 2024, par rus_99_pk

    I'm trying to download a streaming video using ffmpeg. There is a file in the format *.m3u8. BUT, if everything was so simple, I would not have come here.

    


    There are a number of nuances :

    


      

    1. It cannot be downloaded by specifying a link to the file

      2. 


    2. If you upload the file and look at its contents, there will be : #EXT-X-KEY:METHOD=AES-128,URI="[KEY],IV=[IV]

      3. 


    


    With a URI, the task is easy to solve ; just specify the value list.m3u8.

    


    I end up getting :

    


    Error when loading first segment 'https://cdnv-m12.boomstream.com/vod/hash:21596def3216ed982660d609751b8078/id:35105.29443.1039983.85853232.150106.hls/time:0/data:eyJ2ZXJzaW9uIjoiMS4yLjk3IiwidXNlX2RpcmVjdF9saW5rcyI6InllcyIsImlzX2VuY3J5cHQiOiJ5ZXMifQ==/m61/2024/04/27/1Q0idCxb.mp4/media-1.ts'


    


    But with IV it’s more difficult, because file processing is performed on the server side. Please help.

    


    I tried to get JS with similar variable names and monitor network traffic using Wireshark, in the hope of catching a response from the server with IV.

    


    But it didn't help me.

    


    My script for download :

    


    #!/bin/bash
