ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Sat May 13 10:26:16 2023 +0200| [0f501b2ad999a63669b6dd002544a447abd368d4] | committer: Anton Khirnov

fftools/ffmpeg_filter: drop a redundant error message

In case no decoder is available, dec_open() called from ist_use() will
fail with 'Decoding requested, but no decoder found', so this check is
redundant.
