    cut.mp4 I got by this command ffmpeg -ss 00:00:11 -i myfile.mp4 -to 00:00:39 -vf 'drawbox= : x=0 : y=0 : color=invert' cut.mp4

    cut2.mp4 I got by this command ffmpeg -ss 00:00:00 -i myfile.mp4 -to 00:00:10 -c copy cut2.mp4

    I searched a lot - didn’t find any solution, maybe, someone can help me out with this one.

    +++UPDATE+++

    output.mp4 is playable, but looks weird.

  • Setting video stream metadata using Ffmpeg

    26 mai 2015, par Edson Menegatti

    I’m using the JavaCV FFmpegFrameRecorder class to encode Android’s camera preview frames into a video.

    The goal would be to replicate the result of the following command line :

    ffmpeg -i input.mp4 -metadata:s:v:0 rotate="90" output.mp4

    I modified the startUnsafe() method as follows, but it failed to generate the desired output :

    if ((video_st = avformat_new_stream(oc, video_codec)) != null) {
    
        video_c = video_st.codec();
    
        video_c.codec_id(oformat.video_codec());
    
        video_c.codec_type(AVMEDIA_TYPE_VIDEO);
    
        ...
    
        AVDictionary avDictionary = new AVDictionary(null);
    
        av_dict_set(avDictionary, "rotate", "90", 0);
    
        video_st.metadata(avDictionaty);
    
        ...
    
}
    
...
    
avformat_write_header(oc, (PointerPointer) null);

    This still encodes the video correctly, but the added metadata never appears on ffprobe. If it helps, the video encoding is h264.

    By the way, here’s the ffprobe output :

    Any suggestions on why is it failing ? Thanks.

  • How to deal with "Buffer queue overflow, dropping." (ffmpeg)

    1er mai 2015, par whitesiroi

    Sometimes it works great and sometimes I’m getting this message
    [Parsed_overlay_0 @ 0x7f9520518800] [framesync @ 0x7f9521021e28] Buffer queue overflow, dropping.

    by running this command
    ffmpeg -i a1.mp4 -i watermark150x125.png -filter_complex 'overlay=10:10' output.mp4

    I tried different variation of "overlay" like overlay=W-w-5:H-h-5, overlay=10:main_h-overlay_h-10, overlay=main_w-overlay_w-10:main_h-overlay_h-10 - getting the same result.

    Here is the output of the ffmpeg command.
