    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.

  • ffmpeg add a watermark programmatically (overlay filter)

    30 septembre 2014, par Alberto Martín

    I am trying to implement a watermark, a png over a video while the video is playing.

    I configure three filters, as i saw in some examples :

    1. Input video (INPUT 1)

      avfilter_graph_create_filter(&filt_src,avfilter_get_by_name("buffer"),"in", buffersrc_args, NULL,graph);

    2. Png to overlay (INPUT 2)

      avfilter_graph_create_filter(&bufferovrlay_ctx,bufferovrlay, "overlay", argsStrOvrlay, NULL,graph);

    3. Output video (Output)

      avfilter_graph_create_filter(&filt_out, avfilter_get_by_name("ffbuffersink"),"out", NULL, buffersink_params, graph)

    At this point iḿ not sure if i am setting correctly the parameters of the overlay filter, because i did not found any example but the function returns ok.

    After creating the filters i call avfilter_graph_parse2(graph, "overlay", inputs, &outputs)
    also with no error returned.

    Finally i call avfilter_graph_config(graph, NULL); and i get the following error :

    -22 (AVERROR_INVALIDDATA)

    I found a lot of examples but always using the command line. What do you think i am doing wrong ? Someone has an programmatically example ?
