I am trying to set up a small filter graph in order to use the YADIF
implementation in libavfilter...
I have set up an avfilter_graph with 3 filters…
avfilter_register_all();
avfGraph = avfilter_graph_alloc();
AVFilter * bufferFilter, * yadifFilter, * bufferSink;
bufferFilter = avfilter_get_by_name("buffer");
yadifFilter = avfilter_get_by_name("yadif");
bufferSink = avfilter_get_by_name("buffersink”);
/* dynamic configuration here */
avfilter_graph_create_filter(/*done for each filter */);
if (err >= 0) err = avfilter_link(buffer_ctx, 0, yadif_ctx, 0);
if (err >= 0) err = avfilter_link(yadif_ctx, 0, sink_ctx, 0);
if (err>=0) err = avfilter_graph_config(avfGraph, NULL);
Then I feed frames into the graph with:
err = av_buffersrc_add_frame(buffer_ctx, avf);
and pull frames out of the graph with:
AVFrame * oframe = av_frame_alloc();
err = av_buffersink_get_frame(sink_ctx, oframe);
this all seems to work pretty well, except it is holding on to a lot of memory
that is released in avfilter_graph_free()
I suspect it is something dumb, but is there something I need to be doing to
release internal references to some resource?
