  • Not able to generate mp4 using png and mp3 audio

    6 mars 2016, par Bhaskar Dabhi

    I am totally nob to FFMPEG.
    I am trying to generate mp4 video file by merging mp3 and png image.

    When i try converting png image into mp4 it works

    ffmpeg -r 1/5.544000 -i 1.png -qscale 2 1.mp4

    But when i add mp3 audio file then it fails

    ffmpeg -r 1/5.544000 -i 1.png -i 1.mp3 -qscale 2 1.mp4

    Following is the error that i get :

    No pixel format specified, yuv444p for H.264 encoding chosen.
    
Use -pix_fmt yuv420p for compatibility with outdated media players.

[aac @ 0x1476660] The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.

    I tried using -strict -2 but still it fails.

    What wrong in the command ? How to create mp4 using mp3 and png ?

  • flvEncoder .flv output won't convert to .mp4 with ffmpeg

    31 juillet 2013, par Emma Assin

    My current project involves creating a .flv using AIR (using https://github.com/zeropointnine/leelib/tree/master/src/leelib/util/flvEncoder) - which then has to be converted into an .mp4, for which we are using ffmpeg.

    The .mp4 output is the correct dimensions and duration, but blank (no images). Audio is not an issue as the original output has no audio.

  • ffmpeg codec error on audio file

    31 juillet 2013, par foosion

    I have some m4a files that will not play properly using the google music player app on my Android phone, although they play fine on most everything else. I thought the problem was the container and thought "ffmpeg -i bad.m4a -codec copy good.m4a" might help. However, when I run on the problem files, I get error messages. Running this command on non-problem files has not generated error messages.

    Please suggest ways to fix (other than re-encoding).
