  • Non-monotonous DTS when concatenate slowed down video

    23 janvier 2019, par whynotbealion

    Copy from Video StackExchange

    I try to concatenate multiple videos to achieve the following:

    All my videos are in mp4 format. One video is first slowed down, then mixed with audio Videos are concatenated in the following order: Normal video, normal video, slowed-down video (output.mp4), normal video ... The video is slowed down with the following command:

    ffmpeg -y -i raw.mp4 -filter:v 'setpts=1.3333*PTS' silent.mp4

    Audio is added with the following command:

    ffmpeg -y -i silent.mp4 -i audio.mp3 -map 0:0 -map 1:0 output.mp4

    When I concatenate using the Concat demuxer (https://trac.ffmpeg.org/wiki/Concatenate) the audio of the output is not in sync with the video. During the concatenation I get the "Non-monotonous DTS" error.

    I tried the following

    Following this suggestion (https://video.stackexchange.com/a/22941/24238) after I created my slowed down and mixed video (output.mp4) I convert all mp4 videos to mts format. After this I concatenate and with

    ffmpeg -i fullvideo.mts fullvideo.mp4

    I convert the resulting video back to mp4 format. This video plays just fine, but during the convert again I get the following error "Non-monotonous DTS in output stream 0:1; previous: 191803, current: 187633; changing to 191804. This may result in incorrect timestamps in the output file."

    My question

    Even regardless the error the video plays just fine, even in the browser. Does this solution still have a disadvantage or threat? Is there a better solution where I don't get any DTS error? I am thankful for any help as this is all new for me.

  • HLS Event Stream from Azure Blob Storage

    23 janvier 2019, par nemesis_567

    Alright, so I encode videos of around 30 seconds with ffmpeg, the following flags:

    ffmpeg.exe -i \"{filename}\"  -f hls -hls_segment_type fmp4 -hls_flags single_file -hls_time 5 -g 1 \"{outname}.m3u8\"

    This generates a single playlist with an m4s and m3u8 file:

    I take this playlist and append several others that are just the same as they come adding a DIscontinuity tag and between each of them and removing unneeded tags. While doing this I replace the filenames with a working SAS URL for the actual files.

    Which results in files of the following type:

    This stream does not play in chrome with video.js, and only plays in bitmovin client, but it constantly fails with buffer append/stalled errors. In firefox it plays, but without much reliability.

    So what am I doing wrong in this process? I've checked the specification for HLS several times, can't see what I'm doing wrong, or what the player expects.

    Please check hls.js player, with the following URL which uses the stream above to see what I'm talking about. HLS.JS Demo Player With My Playlist

  • Dumping Subtitles From AVPicture into ppm Format File

    23 janvier 2019, par Rishabh Garg

    In FFMPEG sofftware, AVPicture is used to store image data using data pointer and linesizes. It means all subtitles are stored in the form of picture inside ffmpeg . Now I want to dump subtitles from AVPicture in .ppm format file.

    I have written this code to Dump subtitles with the help of data in AVPicture. May be my red,green,blue pixel data may be wrong in the loop.

    w = ctx->sub->rects[0]->w;
h = ctx->sub->rects[0]->h;
line_size = ctx->sub->rects[0]->linesize[0];
int m,n;
FILE *fp = fopen("first.ppm", "wb");
(void) fprintf(fp, "P3\n%d %d\n255\n", w, h);
for (m = 0; m < h; ++m)
{
    for (n = 0; n < line_size; ++n)
    {
            static int r,g,b,a,z;
            uint32_t *pallet = ctx->sub->rects[0]->data[1];
            z = ctx->sub->rects[0]->data[0][n];
            b = pallet[z]&0xFF;
            g = (pallet[z]>>8) & 0xFF;
            r = (pallet[z]>>16)& 0xFF;
            a = (pallet[z]>>24)& 0xFF; 
            fprintf(fp,"%d %d %d %d",b,g,r,a);
    }
    fprintf(fp,"\n");
    fflush(fp); 
}
(void) fclose(fp);

    The program is not dumping subtitles. Only 0 is coming in r,g,b,a by which subtitles are not dumping .

  • ffmpeg avcodec_send_packet/avcodec_receive_frame memory leak

    23 janvier 2019, par G Hamlin

    I'm attempting to decode frames, but memory usage grows with every frame (more specifically, with every call to avcodec_send_packet) until finally the code crashes with a bad_alloc. Here's the basic decode loop:

    int rfret = 0;
while((rfret = av_read_frame(inctx.get(), &packet)) >= 0){
    if (packet.stream_index == vstrm_idx) {

        //std::cout << "Sending Packet" << std::endl;
        int ret = avcodec_send_packet(ctx.get(), &packet);
        if (ret < 0 || ret == AVERROR(EAGAIN) || ret == AVERROR_EOF) {
            std::cout << "avcodec_send_packet: " << ret << std::endl;
            break;
        }

        while (ret  >= 0) {
            //std::cout << "Receiving Frame" << std::endl;
            ret = avcodec_receive_frame(ctx.get(), fr);
            if (ret == AVERROR(EAGAIN) || ret == AVERROR_EOF) {
                //std::cout << "avcodec_receive_frame: " << ret << std::endl;
                av_frame_unref(fr);
                // av_frame_free(&fr);
                break;
            }

            std::cout << "frame: " << ctx->frame_number << std::endl;

            // eventually do something with the frame here...

            av_frame_unref(fr);
            // av_frame_free(&fr);
        }
    }
    else {
        //std::cout << "Not Video" << std::endl;
    }
    av_packet_unref(&packet);
}

    Memory usage/leakage seems to scale with the resolution of the video I'm decoding. For example, for a 3840x2160 resolution video, the memory usage in windows task manager consistently jumps up by about 8mb (1 byte per pixel??) for each received frame. Do I need to do something besides call av_frame_unref to release the memory?

    Update 1: (1/21/2019) Compiling on a different machine and running with different video files I am not seeing the memory usage growing without bound. I'll try to narrow down where the difference lies (compiler?, ffmpeg version?, or video encoding?)

    Update 2: (1/21/2019) Ok, it looks like there is some interaction occurring between ffmpeg and Qt's QCamera. In my application, I'm using Qt to manage the webcam, but decided to use ffmpeg libraries to handle decoding/encoding since Qt doesn't have as comprehensive support for different codecs. If I have the camera turned on (through Qt), ffmpeg decoding memory consumption grows without bound. If the camera is off, ffmpeg behaves fine. I've tried this both with a physical camera (Logitech C920) and with a virtual camera using OBS-Virtualcam, with the same result. So far I'm baffled as to how the two systems are interacting...

  • How to initiate ffmpeg sendcmd at first frame of input

    22 janvier 2019, par WestonC

    I'm trying to scale an input overlayed on an alpha background image over time using sendcmd. Everything is working as expected except the first frame of the output file isn't receiving the command marked with time 0.00, resulting in a single frame of the overlay in the top left corner before jumping to the first command-specified position at frame 2.

    Frame 1 Frame 2

    I've tried specifying the initial position as part of the overlay filter in the main command:

    [0:v][a]overlay=x=main_w-overlay_w-28:y=main_h-overlay_h-25[b]

    which works until the scaling hits a certain threshold and then some sort of bug occurs:

    Resize Bug

    My code that works except for first frame:

    ffmpeg -i AlphaLayer.png -i Test.mp4 -c:v prores_ks -profile:v 4444 -filter_complex "[1:v]scale=1360:-1:eval=init:force_original_aspect_ratio=increase[a];[0:v][a]overlay[b],[b]sendcmd=f=scale4.txt" ScaleTest.mov

    The scale4.txt file looks like this:

    0.00 scale w 1360, h -1;
0.00 overlay x main_w-overlay_w-28; 
0.00 overlay y main_h-overlay_h-25;
30 scale w 1560, h -1;
31 scale w 1660, h -1;
32 scale w 1760, h -1;
33 scale w 1860, h -1;
34 overlay x (main_w-overlay_w)/2;
34 overlay y (main_h-overlay_h)/2;
34 scale w 1920, h -1;
35 scale w 1360, h -1;

    I expect the overlay to be in the specified position at frame 1 of the video, but it is in the default position until frame 2.

    Output log:

    $ ffmpeg -i AlphaLayer.png -i Test.mp4 -c:v prores_ks -profile:v 4444 -filter_complex "[1:v]scale=1360:-1:eval=init:force_original_aspect_ratio=increase[a];[0:v][a]overlay[b],[b]sendcmd=f=scale4.txt" Output.mov
