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.

FFmpeg examples README
----------------------

Both following use cases rely on pkg-config and make, thus make sure
that you have them installed and working on your system.


Method 1: build the installed examples in a generic read/write user directory

Copy to a read/write user directory and just use "make", it will link
to the libraries on your system, assuming the PKG_CONFIG_PATH is
correctly configured.

Method 2: build the examples in-tree

Assuming you are in the source FFmpeg checkout directory, you need to build
FFmpeg (no need to make install in any prefix). Then just run "make examples".
This will build the examples using the FFmpeg build system. You can clean those
examples using "make examplesclean"

If you want to try the dedicated Makefile examples (to emulate the first
method), go into doc/examples and run a command such as
PKG_CONFIG_PATH=pc-uninstalled make.
