#7220: Pointer returned from av_demuxer_iterate() should not be const -----------------------------------+-------------------------------------- Reporter: jlindgren | Type: defect Status: new | Priority: normal Component: avformat | Version: git-master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+-------------------------------------- Summary of the bug: av_demuxer_iterate() was added in commit 0694d8702421 as a replacement for av_iformat_next(). However, it's not a very good replacement since it returns <const AVInputFormat *> instead of <AVInputFormat *>. In order to do anything useful with the returned pointer, such as pass it to avformat_open_input(), it's now necessary to add an ugly cast to get rid of the <const>. This seems like an oversight. How to reproduce: 1. Attempt to use av_demuxer_iterate() in conjunction with the rest of the FFmpeg API. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7220> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
