FFmpeg/libavcodec/allcodecs.c
Michael Niedermayer 42f40d36b7 avcodec/allcodecs: Provide empty codec_list in allcodecs when ossfuzz is used 
The last workaround is not sufficient to make oss fuzz work with the iterate API
as it did not provide a FFmpeg that external libs can be linked to.

This patch does not fully restore the pre iterate functionality. My attempts to
do this have so far failed.

The problem with this solution is that it renders the fuzzers virtual system
ffmpeg (libs) non functional. Which differs from a real system compared to the
virtual system tested by the fuzzer.
It should theoretically not matter as the system ffmpeg wouldnt be used.
But with more cases being fuzzed we likely will hit a case where a external
lib is involved and it does matter ...

Working around this may be possible with weak symbols but so far my attempts
failed

Alternatively multiple ffmpeg could be built, this becomes messy though
quickly as they need to be all linked together. That is we need a FFmpeg
that has the iterate API modified so it can work with the resources
available to ossfuzz. And at the same time we need a ffmpeg that has
its full functionality for any external libs which use ffmpeg and are
used by ffmpeg.
