  • ffmpeg - mp4 video created from images not rendered in browser [on hold]

    6 mai 2014, par mast kalandar

    Using PHP (Symfony) I have extracted set of frames from a video using ffmpeg. Following is the command I’ve used :

    ffmpeg -i f1.mp4 f%d.jpg

    Total 30 frames were created, each one of 1920 x 1020 pixels

    I have added some text in those frames and created one video
    (without changing dimension of any frames)

    ffmpeg -f image2 -r 30 -i f%d.png -r 30 -b:v 5458k my.mp4

    When I try to render this mp4 file in video tag (Chromium & Mozilla Firefox), it is not getting render, however other normal mp4 videos are getting render properly.

    Strange thing is when I open this video directly (http://localhost/MyProject/web/video/user_videos/my.mp4) in Mozilla Firefox, it is getting played in screen properly, however not in Chromium.

    What is the problem here ??

    Do I need to add one second audio as well to my.mp4 file ?

    Kindly suggest if any thing is missing ??

  • How to stop ffmpeg from manipulating mp3 metadata ?

    13 septembre 2024, par he rambled

    I'm using ffmpeg to change bitrate of my mp3 files. It works well, but one thing is very frustrating.

    



    ffmpeg automatically changes some of metadata fields. Specifically it converts ID3v2.3 to ID3v2.4, and it does it incorrectly. For example, it writes TYER field that actually does not exist in ID3v2.4. But the most frustrating thing is, it converts USLT field to lyrics-LANGCODE(like lyrics-eng). Most of music players does not recognise this tag !

    



    I don't want ffmpeg to mess up with metadata fields. I just want it to change bitrate. Is there anyway to tell ffmpeg that it should not touch any metadata fields ?

    



    I'm running ffmpeg 4.0.2 in windows 64bit. Options are :

    



    ffmpeg -i input.mp3 -codec:a libmp3lame -b:a 128k output.mp3


    



    And no, -id3v2_version 3 did not help. It corrected TYER problem, but not lyrics problem.

    


  • Undefined reference to _aacplusEncOpen

    26 décembre 2011, par Tarun

    Following is the copy of my config.log file->

    http://pastebin.com/embed_js.php?i=UyTBTTZv

    Following is copy of configure file->

    http://pastebin.com/embed_js.php?i=2c15zppN

    One more thing..As of now I am trying to cross-compile ffmpeg on ubuntu,But If I just compile it for linux..The same command doesnt gives any error and executes smoothly and then I am able to get ffmpeg with aacplus support for my linux machine, But why the problem is coming when I am cross compiling it.

    Another thing as aacplus is not on by default, If in configuration I dont put any (off by default) library support like if I remove aacplus from it, Then also it goes smoothly.

    Help please ASAP
