WebVTT Audio Descriptions for Elephants Dream
10 mars 2015, par silviaWhen I set out to improve accessibility on the Web and we started developing WebSRT – later to be renamed to WebVTT – I needed an example video to demonstrate captions / subtitles, audio descriptions, transcripts, navigation markers and sign language.
I needed a freely available video with spoken text that either already had such data available or that I could create it for. Naturally I chose “Elephants Dream” by the Orange Open Movie Project , because it was created under the Creative Commons Attribution 2.5 license.
As it turned out, the Blender Foundation had already created a collection of SRT files that would represent the English original as well as the translated languages. I was able to reuse them by merely adding a WEBVTT header.
Then there was a need for a textual audio description. I read up on the plot online and finally wrote up a time-alignd audio description. I’m hereby making that file available under the Create Commons Attribution 4.0 license. I’ve added a few lines to the medadata headers so it doesn’t confuse players. Feel free to reuse at will – I know there are others out there that have a similar need to demonstrate accessibility features.

Convert chapters from xml to ffmetadata ?
3 février 2021, par Soul SparkI wanted to add chapters to my encoded mkvs, but I get
*.xmlfiles when I download it from online. So is there any way to convert it toFFMETADATAFILEso that when I encode it using ffmpeg I can add chapters to my mkv ??


Sample Input



<?xml version="1.0"?>

<chaptertimeend>00:01:30.000000000</chaptertimeend>

<chapterflaghidden>0</chapterflaghidden>

<chapterflagenabled>1</chapterflagenabled>


-<chapterdisplay>

<chapterstring>Chapter 1</chapterstring>

<chapterlanguage>und</chapterlanguage>

</chapterdisplay>

</chapteratom>



</editionentry>

</chapters>



Sample Output

Downloading video & audio segment simultaneously with youtube-dl and ffmpeg
7 décembre 2020, par MtalyFor an online streaming video that I would like to download I have two m3u8 files.


One for the video itself with segment-0.ts to segment-250.ts :


#EXTINF:6.000000,
segment-0.ts
#EXTINF:6.000000,
segment-1.ts
#EXTINF:6.000000,
segment-2.ts
#EXTINF:6.000000,
segment-3.ts
#EXTINF:6.000000,
segment-4.ts


and another m3u8 for the audio segments :


#EXTINF:6.016000,
segment-0.aac
#EXTINF:6.016000,
segment-1.aac
#EXTINF:6.016000,
segment-2.aac
#EXTINF:6.016000,
segment-3.aac
#EXTINF:6.016000,


So, I use youtube-dl and ffmpeg to download the both m3u8 separately then merge them to get the final mp4 (audio+video).


Is there a way to merge the files or use a combined command in the Terminal to automatically download both and merge them ?
