  • FFMPEG unwanted rotation

    5 mars 2015, par Ben

    When I add a watermark image with a landscape orientation to a video that has a portrait orientation the video automatically rotates to landscape. How do I prevent this ? Also, the audio file isn’t being merged into the output. How can I include the audio.mp3 to be the sole audio track ?

  • setPTS outputting wrong duration (Ffmpeg)

    16 septembre 2020, par WebDiva

    I have a video of duration 14 seconds. I applied the setPTS filter to make it 3 times slow. So the total duration should be 42s (14*3). But the output gives a 49s long video. Here is the command :

    


    ffmpeg -i video.mp4 -filter_complex "[0:v]setpts=3*PTS[v];[0:a]atempo=0.6,atempo=0.5[a]" -map "[v]" -map "[a]" output.mp4


    


    What is wrong with this command ? I tried it for different videos but all has the same weird issue. Any help will be appreciated. Regards.

  • C++ FFmpeg create mp4 file

    1er février 2021, par DDovzhenko

    I'm trying to create mp4 video file with FFmpeg and C++, but in result I receive broken file (windows player shows "Can't play ... 0xc00d36c4"). If I create .h264 file, it can be played with 'ffplay' and successfully converted to mp4 via CL.

    



    My code :

    



    int main() {
    char *filename = "tmp.mp4";
    AVOutputFormat *fmt;
    AVFormatContext *fctx;
    AVCodecContext *cctx;
    AVStream *st;

    av_register_all();
    avcodec_register_all();

    //auto detect the output format from the name
    fmt = av_guess_format(NULL, filename, NULL);
    if (!fmt) {
        cout << "Error av_guess_format()" << endl; system("pause"); exit(1);
    }

    if (avformat_alloc_output_context2(&fctx, fmt, NULL, filename) < 0) {
        cout << "Error avformat_alloc_output_context2()" << endl; system("pause"); exit(1);
    }


    //stream creation + parameters
    st = avformat_new_stream(fctx, 0);
    if (!st) {
        cout << "Error avformat_new_stream()" << endl; system("pause"); exit(1);
    }

    st->codecpar->codec_id = fmt->video_codec;
    st->codecpar->codec_type = AVMEDIA_TYPE_VIDEO;
    st->codecpar->width = 352;
    st->codecpar->height = 288;
    st->time_base.num = 1;
    st->time_base.den = 25;

    AVCodec *pCodec = avcodec_find_encoder(st->codecpar->codec_id);
    if (!pCodec) {
        cout << "Error avcodec_find_encoder()" << endl; system("pause"); exit(1);
    }

    If I will try to play mp4 file with 'ffplay' it prints :

    I've spent a lot of time without success of finding issue, what could be the reason of it ?

    



    Thank for help !
