Pushing bmp frames using appsrc

[Peto]

Hi guys,

I need to create a pipeline into which I can push images and they are
streamed as video using HLS.
I started simple and created a following pipeline:

appsrc -> avdec_bmp -> videoconvert -> queue -> autovideosink

where appsrc has following configuration:

caps=image/bmp,framerate=0/1,width=900,height=374
stream-type=0 // No seeking
format=3 // time
do-timestamp=true

But when I push images into the pipeline, my process crashes after a
few images are pushed.
I am trying it on Windows 10, installed
gstreamer-1.0-x86_64-1.14.0.1.msi,
gstreamer-1.0-devel-x86_64-1.14.0.1.msi and
I am using C# Visual Studio 2017

With GST_DEBUG=3 I get following log messages:
