[FFmpeg-devel] [PATCH] avformat/segafilmenc: Fix division by zero with malformed Cinepak data

The film_write_packet() function reads encoded_buf_size from packet data via AV_RB24() and uses it in a modulo operation without validation. When the data contains zeros at this position, it causes division by zero. Add validation to return AVERROR_INVALIDDATA when encoded_buf_size is zero. Signe
