Andreas Cadhalpun dd6c8575db examples/demuxing_decoding: use properties from frame instead of video_dec_ctx
This is more robust.

And only check if there is actually a frame returned.

Andreas Cadhalpun 078be09dd7 examples/demuxing_decoding: abort decoding when width, height or pix_fmt change
This is necessary, because avcodec_decode_video2 can change
width, height and/or pixel format of the AVCodecContext. Since
video_dst_data and video_dst_linesize are not updated by calling
av_image_alloc again, av_image_copy[_plane] asserts, because the
destination buffer is too small.

In this case, creating a useable rawvideo is not possible anyway, since
it has fixed width/height/pix_fmt.

Even Wiik Thomassen 43f116d162 examples/demuxing_decoding: return error when no codec found
The open_codec_context function, when it fails to find a codec, now
return AVERROR(EINVAL) to signal an error.

Before it would return the stream index, which was always >= 0, and
continue as if a codec was found. This change make it fail faster,
instead of repeated failed tries to decode frames with no codec.

Clément Bœsch fb10b43fc4 doc/examples: rename demuxing to demuxing_decoding.
That example shows how the decoding process works, not only the
demuxing.
