• Download m3u8 playlist and merge into one C#

  10 août 2014, par trinvh

  Solution 1 :

  I tried this by using create a ffmpeg wrapper, read output from cmd with following command :

  -i \"{m3u8-url-for-download}\" -y -c copy -bsf:a aac_adtstoasc \"{destination-filename}\"

  I can get duration, current state for downloading. Everything seems be ok. However sometimes it crashed and I can’t detect why. It isn’t ALWAYS, but SOMETIME.

  Solution 2 :

  I download m3u8 playlist file and get contents within it. It contains an array *.ts file url that I can easily download by using HttpClient. But I don’t know how to combine these *.ts file into one mp4 file that keeps their format.

  Are there other solutions for doing this ?

• Download ONLY audio from a youtube video

  30 avril 2017, par Feras

  I know that there are a million ways to download a video from youtube and then convert it to audio or do further processing on it. But recently I was surprised to see an app called YoutubeToMp3 on mac actually showing "Skipping X mb of video" and supposedly only downloading the audio from the video, without the need to use bandwith to download the entire video and then convert it. I was wondering if this is actually correct and possible at all because I cant find any way to do that. Do you have any ideas ?

  EDIT :
  After some tests here is some additional information on the topic. The video which I tried to get the audio from is just a sample mp4 file from the internet :

  http://download.wavetlan.com/SVV/Media/HTTP/MP4/ConvertedFiles/MediaCoder/MediaCoder_test6_1m9s_XVID_VBR_306kbps_320x240_25fps_MPEG1Layer3_CBR_320kbps_Stereo_44100Hz.mp4

  I tried

  ffmpeg -i "input" out.mp3

  ffmpeg -i "input" -vn out.mp3

  ffmpeg -i “input” -vn -ac 2 -ar 44100 -ab 320k -f mp3 output.mp3

  ffmpeg -i “input” -vn -acodec copy output.mp3

  Unfortunately non of these commands seems to be using less bandwith. They all download the entire video. Now that you have the video can you confirm if there is actually a command that downloads only the audio stream from it and lowers the bandwith usage ? Thanks !
