  • FFMPEG adds extra contents to the beginning of the file, when converting OGG audio to MP3

    3 décembre 2018, par PBM

    I use the following ffmpeg -i   to convert ogg music files to mp3. I, however, realized that the resulting mp3 files on some ogg files are slightly longer, and includes the repetition of the first half a second of the original file in the beginning. (Which is quite annoying when listening to the MP3s).

    Anybody else faced similar issues ?

    FYI, I am using ffmpeg version 4.0.3, which uses libmp3lame as the encoder for MP3 output.

    As requested in the comments, here is the full log of @ffmpeg@

    $ ffmpeg -i track.ogg track.mp3

  • How to stream to the stream name come in response from Youtube livestream api

    I see a response like this, When I use OBS to stream to this RMTP URL it doesn’t have the title I set in the stream as you can see come in response. I am getting stream name but not sure if I do it correctly.

    If I call the path as rtmp://a.rtmp.youtube.com/live2/steamnamefromurl/mykey
    it’s work but not have the title I set by call API. Anyone please check the page and help what I am going wrong. What I am looking for is get the title and description set for stream, or verified that I am doing it correctly.
