ffmpeg - splitting, overlaying and selecting frame range in multiple input/outputs with complex video filter producing empty output

11 octobre 2017, par Josep Carner

I am trying to use ffmpeg to apply multiple filters -single input, multiple outputs-. In concrete, I am splitting the output in two, then applying an overlaying patch to one of those streams, split again and select a time range. The command I am using is :

   ffmpeg \

    -i ./dataset_test/videos/jz_10_huron_barstow.mkv \

    -an \

    -sn \

    -loglevel error \

    -filter_complex \

        "[0:v]split=2[L_in][F_in];

         [L_in]

            crop=226:307:21:74,scale=200x200,setdar=200:200,split=2\

         [L_in_0][L_in_1];\

         color=#808080:226x307,setpts=PTS-STARTPTS[L_PATCH];\

         [F_in][L_PATCH]

            overlay=21:74:shortest=1,scale=200x200,setdar=200:200,split=2\

         [F_in_0][F_in_1];\

         [F_in_0]select='between(t\,32\,212)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[F_0];\

         [F_in_1]select='between(t\,213\,393)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[F_1];\

         [L_in_0]select='between(t\,32\,212)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[L_0];\

         [L_in_1]select='between(t\,213\,393)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[L_1]\

         "\

    -map [F_0] -an -sn ./out/jz_10_huron_barstow/F/0_F.mp4\

    -map [F_1] -an -sn ./out/jz_10_huron_barstow/F/1_F.mp4\

    -map [L_0] -an -sn ./out/jz_10_huron_barstow/L/0_L.mp4\

    -map [L_1] -an -sn ./out/jz_10_huron_barstow/L/1_L.mp4\

For some reason, 0_F.mp4 is empty and 1_F.mp4 is cropped. My intuition is that it has something to do with applying splitting + overlaying + selecting. I think at some point some filter before select is changing the PTS of the frames in some way select is not properly discarding them, but I honestly don’t know how to solve it. Some insights :

L_0 and L_1 are fine (no overlay is used in those two)
If I suppress L outputs everything works fine (no "split" is needed at the beginning)

Could someone provide some light ? I don’t really know what else to try.
The logs with loglevel 40 are (some repeated lines ommited) :

PHPVideoToolkit Error...how to rcover from it [on hold]

12 octobre 2017, par Majharul Mondal

PHPVideoToolkit Error : Execute error. Output for file "/var/www/html/phpvideotoolkit-2014-06-05/examples/tmp/1507804070-59df43a6aa8d9/tmp_%d.jpg" was not found. Please check server write permissions and/or available codecs compiled with FFmpeg. You can check the encode decode availability by inspecting the output array from PHPVideoToolkit::getFFmpegInfo().

Any thing i have to install. I am using php5,laravel

Converting uint8_t data to AVFrame with FFmpeg

30 octobre 2017, par J.Lefebvre

I am currently working in C++ with the Autodesk 3DStudio Max 2014 SDK (toolset 100) and the Ffmpeg library in Visual Studio 2015 and trying to convert a DIB (Device Independent Bitmap) to uint8_t pointer array and then convert these data to an AVFrame.

I don’t have any errors, but my video is still black and without meta data.
(no time display, etc)

I made approximatively the same with a Visual Studio Console application to convert jpeg image sequence from disk and this is working fine.
(The only difference is that instead of converting jpeg to AVFrame with the Ffmpeg library, I try to convert raw data to an AVFrame.)

So I think the problem could be either on the DIB conversion to the uint8_t data or the uint8_t data to the AVFrame.
(The second is more plausible, because I used the SFML library to display a window with my rgb uint8_t* data for debuging and it is working fine.)

I first initialize the ffmpeg library :

This function is called once at the beginning.

int Converter::Initialize(AVCodecID codec_id, int width, int height, int fps, const char *filename)

{

    avcodec_register_all();

    av_register_all();



    AVCodec *codec;

    inputFrame = NULL;

    codecContext = NULL;

    pkt = NULL;

    file = NULL;

    outputFilename = new char[strlen(filename)]();

    *outputFilename = '\0';

    strcpy(outputFilename, filename);



    int ret;



    //Initializing AVCodecContext and getting PixelFormat supported by encoder

    codec = avcodec_find_encoder(codec_id);

    if (!codec)

        return 1;



    AVPixelFormat pixFormat = codec->pix_fmts[0];

    codecContext = avcodec_alloc_context3(codec);

    if (!codecContext)

        return 1;



    codecContext->bit_rate = 400000;

    codecContext->width = width;

    codecContext->height = height;

    codecContext->time_base.num = 1;

    codecContext->time_base.den = fps;

    codecContext->gop_size = 10;

    codecContext->max_b_frames = 1;

    codecContext->pix_fmt = pixFormat;



    if (codec_id == AV_CODEC_ID_H264)

        av_opt_set(codecContext->priv_data, "preset", "slow", 0);



    //Actually opening the encoder

    if (avcodec_open2(codecContext, codec, NULL) &lt; 0)

        return 1;



    file = fopen(outputFilename, "wb");

    if (!file)

        return 1;



    inputFrame = av_frame_alloc();

    inputFrame->format = codecContext->pix_fmt;

    inputFrame->width = codecContext->width;

    inputFrame->height = codecContext->height;



    ret = av_image_alloc(inputFrame->data, inputFrame->linesize, codecContext->width, codecContext->height, codecContext->pix_fmt, 32);



    if (ret &lt; 0)

        return 1;



    return 0;

}

Then for each frame, I get the DIB and convert to a uint8_t* it with this function :

uint8_t* Util::ToUint8_t(RGBQUAD *data, int width, int height)

{

    uint8_t* buf = (uint8_t*)data;



    int imageSize = width * height;

    size_t rgbquad_size = sizeof(RGBQUAD);

    size_t total_bytes = imageSize * rgbquad_size;

    uint8_t * pCopyBuffer = new uint8_t[total_bytes];



    for (int x = 0; x &lt; width; x++)

    {

        for (int y = 0; y &lt; height; y++)

        {

            int index = (x + width * y) * rgbquad_size;

            int invertIndex = (x + width* (height - y - 1)) * rgbquad_size;



            //BGRA to RGBA

            pCopyBuffer[index] = buf[invertIndex + 2];

            pCopyBuffer[index + 1] = buf[invertIndex + 1];

            pCopyBuffer[index + 2] = buf[invertIndex];

            pCopyBuffer[index + 3] = 0xFF;

        }

    }



    return pCopyBuffer;

}



void GetDIBBuffer(Interface* ip, BITMAPINFO *bmi, uint8_t** outBuffer)

{

    int size;



    ViewExp&amp; view = ip->GetActiveViewExp();



    view.getGW()->getDIB(NULL, &amp;size);



    bmi = (BITMAPINFO *)malloc(size);

    BITMAPINFOHEADER *bmih = (BITMAPINFOHEADER *)bmi;

    view.getGW()->getDIB(bmi, &amp;size);



    uint8_t * pCopyBuffer = Util::ToUint8_t(bmi->bmiColors, bmih->biWidth, bmih->biHeight);



    *outBuffer = pCopyBuffer;

}

This function is used to get the DIB :

void GetViewportDIB(Interface* ip, BITMAPINFO *bmi, BITMAPINFOHEADER *bmih, BitmapInfo biFile, Bitmap *map)

{

    int size;



    if (!biFile.Name()[0])

        return;



    ViewExp&amp; view = ip->GetActiveViewExp();



    view.getGW()->getDIB(NULL, &amp;size);



    bmi = (BITMAPINFO *)malloc(size);

    bmih = (BITMAPINFOHEADER *)bmi;



    view.getGW()->getDIB(bmi, &amp;size);



    biFile.SetWidth((WORD)bmih->biWidth);

    biFile.SetHeight((WORD)bmih->biHeight);

    biFile.SetType(BMM_TRUE_32);



    map = TheManager->Create(&amp;biFile);

    map->OpenOutput(&amp;biFile);

    map->FromDib(bmi);

    map->Write(&amp;biFile);

    map->Close(&amp;biFile);

}

And after the conversion to AVFrame and video encoding :

The EncodeFromMem function is call each frame.

int Converter::EncodeFromMem(const char *outputDir, int frameNumber, uint8_t* data)

{

    int ret;



    inputFrame->pts = frameNumber;

    EncodeFrame(data, codecContext, inputFrame, &amp;pkt, file);



    return 0;

}



static void RgbToYuv(uint8_t *rgb, AVCodecContext *c, AVFrame *frame)

{

    struct SwsContext *swsCtx = NULL;

    const int in_linesize[1] = { 3 * c->width };// RGB stride

    swsCtx = sws_getCachedContext(swsCtx, c->width, c->height, AV_PIX_FMT_RGB24, c->width, c->height, AV_PIX_FMT_YUV420P, 0, 0, 0, 0);

    sws_scale(swsCtx, (const uint8_t * const *)&amp;rgb, in_linesize, 0, c->height, frame->data, frame->linesize);

}



static void EncodeFrame(uint8_t *rgb, AVCodecContext *c, AVFrame *frame, AVPacket **pkt, FILE *file)

{

    int ret, got_output;



    RgbToYuv(rgb, c, frame);



    *pkt = av_packet_alloc();

    av_init_packet(*pkt);

    (*pkt)->data = NULL;

    (*pkt)->size = 0;



    ret = avcodec_encode_video2(c, *pkt, frame, &amp;got_output);

    if (ret &lt; 0)

    {

        fprintf(stderr, "Error encoding frame/n");

        exit(1);

    }

    if (got_output)

    {

        fwrite((*pkt)->data, 1, (*pkt)->size, file);

        av_packet_unref(*pkt);

    }

}

To finish I have a function that write the packets and free the memory :
This function is called once at the end of the time range.

int Converter::Finalize()

{

    int ret, got_output;

    uint8_t endcode[] = { 0, 0, 1, 0xb7 };



    /* get the delayed frames */

    do

    {

        fflush(stdout);

        ret = avcodec_encode_video2(codecContext, pkt, NULL, &amp;got_output);

        if (ret &lt; 0)

        {

            fprintf(stderr, "Error encoding frame/n");

            return 1;

        }

        if (got_output)

        {

            fwrite(pkt->data, 1, pkt->size, file);

            av_packet_unref(pkt);

        }

    } while (got_output);



    fwrite(endcode, 1, sizeof(endcode), file);

    fclose(file);



    avcodec_close(codecContext);

    av_free(codecContext);



    av_frame_unref(inputFrame);

    av_frame_free(&amp;inputFrame);

    //av_freep(&amp;inputFrame->data[0]); //Crash



    delete outputFilename;

    outputFilename = 0;



    return 0;

}

EDIT :

I modify my RgbToYuv function and create another one to convert back the yuv frame to an rgb one.

This not really solve the problem, but maybe focus the problem on the conversion from YuvToRgb.

This is the result of the conversion from YUV to RGB :

![YuvToRgb result] : https://img42.com/kHqpt+

static void YuvToRgb(AVCodecContext *c, AVFrame *frame)

{

    struct SwsContext *img_convert_ctx = sws_getContext(c->width, c->height, AV_PIX_FMT_YUV420P, c->width, c->height, AV_PIX_FMT_RGB24, SWS_BICUBIC, NULL, NULL, NULL);

    AVFrame * rgbPictInfo = av_frame_alloc();

    avpicture_fill((AVPicture*)rgbPictInfo, *(frame)->data, AV_PIX_FMT_RGB24, c->width, c->height);

    sws_scale(img_convert_ctx, frame->data, frame->linesize, 0, c->height, rgbPictInfo->data, rgbPictInfo->linesize);



    Util::DebugWindow(c->width, c->height, rgbPictInfo->data[0]);

}

static void RgbToYuv(uint8_t *rgb, AVCodecContext *c, AVFrame *frame)

{

    AVFrame * rgbPictInfo = av_frame_alloc();

    avpicture_fill((AVPicture*)frame, rgb, AV_PIX_FMT_YUV420P, c->width, c->height);    

    sws_scale(swsCtx, rgbPictInfo->data, rgbPictInfo->linesize, 0, c->height, frame->data, frame->linesize);



    YuvToRgb(c, frame);
