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.

Per the ffmpeg documentation I'm trying to switch the video's audio output to japanese. However, the output video is still in english (which it was in before). This is my current ffmpeg cmd :


ffmpeg -i "my_vid.mp4" -c copy -disposition:a:1 default "output.mp4"



what am I doing wrong ? Still pretty new to ffmpeg


Edit :


With one of the suggestions I tried adding the -map 0 option to my command


ffmpeg -i "my_vid.mp4" -map 0 -c copy -disposition:a:2 default "output.mp4"



but still not change. The meta data for the output video is as follows :
