Hello,
Im currently working on a video player software, which should be based
on ffmpeg tools and at the moment of writing, using SDL2 for display
of the video content.
The documentation for ffmpeg is a bit difficult to get through, as
most example code seems to be outdated or using deprecated features.
The SDL tutorial is also not valid anymore, as well as the updated
version on Github or other information which can be found using a
search engine of choice.
What am I missing out here, the alignment?
You are missing several things. First you need to call
avcodec_receive_frame to get the returned frame after
avcodec_send_packet. See the docs for the function and this blog.

Also, you don't need to set anything to writable or check for it.
Finally, I would look at the code in ffplay.c as it is now compatible
with sdl2, I believe.
