* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-27
| | | | | | | | | | Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

| | | | | | | | | | | | | | | | | | | | | | The input data must remain constant, make a copy instead. This is in theory a performance hit, but since I failed to find any samples using this feature, this should not matter in practice. Also, check the size of the header, avoiding invalid reads on truncated data. CC:libav-stable@libav.org
