  • FFmpeg Failed to inject frame into filter network : Out of memory

    3 mars 2019, par CoXier

    Recently I build ffmpeg and use it on Android device. Anything works well except such videos with metadata rotate. Here is my command :

    [ffmpeg, -i, input.mp4, -ss, 0.0, -t, 4.748, -vcodec, libx264, -preset, ultrafast, -acodec, copy, -vf, scale=500:-2, -y, output.mp4]

    Error log is here.

    In my opinion, if ffmpeg detect input video with rotate metadata, it will first rotate it in memory and then apply filters on the tmp videos.

    I can use noautorotate to solve the crash. However the filter applied on the video is wrong because ffmpeg does not rotate the input video.

    Can anyone explains what I guess is right or not ? And if you know how to solve this crash, I will appreciate it.

  • What are the licence free codecs for FFMPEG ?

    8 avril 2024, par FunkyPizza

    So I've recently started implementing ffmpeg in an application that I do intend to distribute commercially. And I've had an hard time getting my head around the whole licensing process.

    



    The most commonly answered question I've seen seems to be about x264 which requires a paid licence from x264.org in order to use it commercially (right ?). I started to look into mpeg4 instead but that too seemed to be locked behind some patent licensing fee (https://www.mpegla.com/programs/mpeg-4-visual/license-agreement/).

    



    I guess my question is the following, what video encoders compatible with FFMPEG are fully free to use ?

    



    Yes I barely know what I'm talking about, but I feel like I'm missing the elephant in the room here...
