gstreamer: m3u8 to mkv/kinesis video fails

I want to ingest a m3u8 stream to kinesis video (MKV format). I compiled the kvssink plugin but gstreamer fails with unknown error.

Maybe I need to convert the stream somehow before sending to kvssink? Could someone comment on this point?

Command:

gst-launch-1.0 souphttpsrc  location=http://devimages.apple.com/iphone/samples/bipbop/gear4/prog_index.m3u8 ! hlsdemux ! video/x-h264, format=avc,alignment=au ! h264parse ! kvssink stream-name="my-stream" storage-size=128 access-key="<key>" secret-key="<secret>"

Error

Stream is ready
Pipeline is live and does not need PREROLL ...
Got context from element 'souphttpsrc0': gst.soup.session=context, session=(SoupSession)NULL, force=(boolean)false;
Setting pipeline to PLAYING ...
New clock: GstSystemClock

UPDATE

after small changes it works now with fakesink but still get an error for kvssink

problem solved, seems to be an issue in current kvssink version, with older commits it works

see https://github.com/awslabs/amazon-kinesis-video-streams-producer-sdk-cpp/issues/396

The failure is in the HLS demux element. You could try to get your GStreamer pipeline working with the fakesink and once that's working, you can attempt to link the KVS GST plugin.

The KVS GST plugin related questions can be posted in GitHub issues in: https://github.com/awslabs/amazon-kinesis-video-streams-producer-sdk-cpp/issues

video/x-h264, format=avc,alignment=au I don't think you can just dictate caps in that way. It will just get in the way of auto-negotiating caps.

Also you don't seem to have a H.264 decoder in that pipeline.
