Description EndlessEden 2021-11-12 21:12:19 UTC 
SUMMARY

starting with ffmpeg version 4.3, changes to libavformat/libavcodec break building against these versions.

Currently when attempting to build against these versions, it fails with "no matching function for call to 'av_find_best_stream'"

'av_find_best_stream' is specified in <libavformat/avformat.h>; however this header is not included in ffmpegthumbnailer/moviedecoder.cpp 

if the header is added [#include <libavformat/avformat.h>], and rebuilt it results in a new error " error: invalid conversion from ‘AVCodec**’ to ‘const AVCodec**’"

This build error ive seen in other projects (decord): (See: https://github.com/dmlc/decord/pull/160)
