Hi, I'using a filesrc, decodebin2, ffmpegcolorspace, capsfilter and appsink pipeline which I use in pull mode. This means I pull the data of the appsink in a worker thread. I also set the 'max-size-bytes' property of the decodebin2 to 1000000 and the gst_app_sink_set_max_buffers to 1. Anyhow after starting the pipeline, the memory consumption is rised up to more than 1gb, which decreases slowly while playing. If I delete the pipeline all memory is freed. Who does take this memory?
