Stripping out non-English streams in ffmpeg
2 septembre 2021, par Dennis Q. WilsonI have many MKV files containing audio and subtitle streams in multiple languages, and I want to strip out the non-English ones. To the best of my understanding, the command below should achieve this, except it copies only the first English-language audio and subtitle stream it encounters, ignoring any subsequent streams containing audio commentary and the like. What am I doing wrong ?


ffmpeg.exe -i INPUT.mkv -map 0:v:0 -map -0:a -map 0:a:m:language:eng -map -0:s -map 0:a:s:language:eng -c copy OUTPUT.mkv

How to downloaded embedded videos on Instagram that have multiple media network requests ? (ffmpeg / curl)
21 octobre 2022, par flhuI was wondering whether it is still possible to download the stories on Instagram that have multiple media network requests nowadays. Previously, I could simply download them using the Firefox Media Page Info View. This is still possible for some content such as reels or by using ffmpeg / curl. I have posted the network behaviour when I load a story on Instagram and a Reel on Instagram. I could not figure out which of the network requests is the relevant one (assuming it is the request with the biggest size) and when downloading it, the VLC player does not recognise the video.


Instagram Reel Network Request


Instagram Stories Network Request


When using the Firefox Media Page Info View, it is possible to download the content from the reel directly whereas the mp4 media file is greyed out.


I tried to copy the URL from the network request using :


ffmpeg -i -c copy 


Copying the corresponding curl request but also only works for the Reel where the HTTP response status codes is 206 (Reel) instead of 200 (Story).
