[FFmpeg-devel] [PATCH 3/3] ffmpeg: only count got_output/errors in decode_error_stat

[Andreas Cadhalpun]

If threading is used, the first (thread_count - 1) packets are read
before any frame/error is returned. Counting this as successful decoding
is wrong, because it also happens when no single frame could be decoded.
