  • How to switch between audio streams added using ffmpeg on an iPhone ?

    24 décembre 2019, par Tony M

    I have an m.mp4 with English audio and want to add a second audio stream in Italian so that I can play either language using the iPhone. When I used this command :

    ffmpeg -i m.mp4 -i ita.mp3 -c copy -map 0 -map 1 out.mp4

    The output from ffmpeg -i out.mp4 (see below) shows that a new audio stream is added, yet when I transfer the video to the TV app and play it on either MacOS or iOS it only plays the original English and I see no options to play other languages.

    How do I get it to be able to switch between either audio ?

    Here is the output from ffmpeg -i out.mp4:

        Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 400x300 [SAR 1:1 DAR 4:3], q=2-31, 482 kb/s, 23.98 fps, 23.98 tbr, 24k tbn, 24k tbc (default)

  • Add a 2nd audio stream using ffmpeg so you can switch audio streams on iOS ?

  • DWT of frames by FFMPEG API

    13 mars 2015, par Vaigard

    How can I spend the DWT Y component is considered of H.264 video frame ? Do not quite understand the principle of filling the structure DWTContext and its schema. And is not a matter of AVFrame->data[0][x] values are already converted, for example by DCT ?

    Thanks and sorry for my English=)
