  • Re-encode video stream only with ffmpeg (and with all audio streams)

    25 septembre 2016, par razr

    I’m looking for a way to re-encode the video stream of a movie only and keep all other streams as they are using ffmpeg or more specific streamio/streamio-ffmpeg (Github - StreamIO-FFMPEG).

    I already tried various combinations of -map 0 or -map a:0 -map s:0, but in all combinations I tried, either nothing is encoded at all, or not all other streams are copied to the new file. In most cases there is only one audio stream after encoding, when there were two before, and sometimes the subtitle streams are lost, too. Also most times the info what language the streams are in gets lost.

    So when I have a movie file (mkv) with the following streams :

    0: video [H.264, 1080p]
    
1: audio [english, mp3]
    
2: audio [french, mp3]
    
3: subtitle [english (forced)]
    
4: subtitle [english]

    What should the ffmpeg parameters be, if I want to encode the video file to H.265 and 720p and keep all other streams as they are ?

    What should the parameters be, if I additionally want to encode the audio streams as AAC ?

    Thanks in advance !

  • Monitor HLS and ICY streams metadata with ffmpeg

    4 juillet 2021, par Кирилл Зайдулин

    Do anyone know is it possible to continuously output the name of playing song for the HLS or ICY streams ?

    


    For ICY streams I found the possible solution : ffmpeg -i "http://media-ice.musicradio.com/CapitalMP3" output.aac -v trace — with "-v trace" option it will output a lot of extra information + updates of metadata.
But for HLS this approach is not working, metadata is not refreshing when song changed.

    


    Any help would be nice. Thanks !

    


  • How to set default streams with ffmpeg

    29 décembre 2015, par Sam

    I have some m4v files that I am wanting to add subtitles to with ffmpeg. I know I need to map the streams to get them into the output file but how do I ensure that this subtitle stream will be a default stream ? The subtitles are .srt and people seem to be saying that they are not compatible with mp4 containers, what do I need to convert the subtitles to first ?

    Also, does it matter what order the various streams are in ? Does the video stream always have to come first, followed by the audio, then the subtitles ? Or can you mix them up however you want ? Does it make any difference ?

    Lastly, what is the difference between a default stream and a forced stream ?
